Cartier Cartier Tonneau, Reference 22051 A yellow gold wristwatch Circa 1989 Dial: silvered Calibre: cal. 78-1 manual winding, 17 jewels Case: 18k yellow gold, case back secured by 4 screws Case number: N°20 III, A102777 Closure: associated alligator strap and stainless steel pin buckle Dimensions: 26 x 39 mm Signed: case, dial and movement Box: no Papers: no Accessories: Cartier travel pouch Total approximate weight including strap 34.5 g The Cartier Tonneau reference 22051 is a striking example of the maison’s innovative approach to watch design, combining bold geometry with timeless elegance.

Reference 22051 exemplifies Cartier’s mastery of form and proportion, with its clean dial layout, elegant Roman numerals, and signature blued steel hands providing a refined counterpoint to the sculptural case. The watch’s understated sophistication is enhanced by meticulous finishing and attention to detail, hallmarks of Cartier craftsmanship.

Cartier Cartier ’Tank Rectangle’ A yellow gold wristwatch Circa 1960 Dial: silvered Calibre: cal. 9P Piaget manual winding, 18 jewels Movement number: 605’925 Case: 18k yellow gold, snap-on back Case number: 015’341 Closure: associated leather strap and 18k pink gold Cartier folding buckle Size: 23 x 27 mm Signed: case, dial and Piaget movement Box: no Papers: no Accessories: associated travel pouch Total approximate weight including strap 35.3 g The present Cartier Tank Rectangulaire from circa 1960 is a beautifully preserved example of Cartier’s mid-century design language, distinguished not only by its elegant proportions but also by the presence of the renowned Piaget 9P movement. A collaboration between two of the era’s most respected maisons, the pairing of Cartier’s iconic case design with Piaget’s ultra-thin mechanical expertise results in a watch of exceptional refinement. Introduced in 1957, Piaget’s 9P quickly became one of the world’s thinnest hand-wound calibers and was celebrated for its reliability, finishing, and remarkable slimness. Its integration into Cartier’s Tank models allowed for a sleeker, more sophisticated profile, enhancing the watch’s already timeless silhouette. The slender case, elongated rectangular form, and classic Roman numeral dial bring forward the purity and restraint that have defined the Tank for over a century. Surviving examples from this period—particularly those housing the coveted 9P—are increasingly scarce, as many were produced in very limited numbers. This 1960 Tank Rectangulaire represents a rare opportunity to acquire a historically significant collaboration between Cartier and Piaget, embodying the pinnacle of mid-century elegance and mechanical artistry.

Introduced as an accessible yet impeccably stylish reinterpretation of the iconic Santos, the 2961 preserves the strong geometric lines and exposed screws that have defined the model since its debut, while offering a fresh, contemporary expression of Cartier’s design language. Crafted with the distinctive squared case and softly rounded edges of the classic Santos Carrée, the reference 2961 embodies the chic minimalism that made the Les Must collection a cultural touchstone in the late 20th century. Its clean dial, elegant proportions, and signature Cartier aesthetic combine to create a watch that is both effortlessly wearable and instantly recognisable.

Cartier Cartier Cristallor Jumbo, Reference 78096 A yellow gold wristwatch Circa 1970 Dial: blanc Calibre: cal. 78-1 manual winding, 17 jewels Movement number: 605’925 Case: 18k yellow gold, back secured 4 screws Case number: G24314, 0471 Closure: associated leather strap and 18k yellow gold Cartier folding buckle Size: 28 x 35 mm Signed: case, dial and movement Box: no Papers: no Accessories: Cartier leather pouch The Cartier Cristallor Jumbo reference 78096 is one of the maison’s most striking and seldom-seen creations, distinguished by its dramatic geometric form and commanding wrist presence. This reference departs boldly from traditional case shapes, embracing a faceted architecture that reflects the brand’s longstanding fascination with strong lines and unconventional design. The oversized, multi-angled case of the 78096 creates a jewel-like effect, with each surface playing with light in a manner reminiscent of a cut crystal—an aesthetic that gives the Cristallor its name. This architectural design is complemented by a clean, minimalist dial that allows the unique case geometry to take center stage, embodying Cartier’s mastery of elegant restraint within avant-garde forms. Produced in notably small quantities, the Cristallor Jumbo is far rarer than many of Cartier’s more familiar shaped watches. Its scarcity, combined with its unmistakable silhouette, has made it increasingly sought after by collectors who appreciate the maison’s boldest design experiments. An example of the reference 78096 in well-preserved condition presents an outstanding opportunity to acquire one of Cartier’s most distinctive and sculptural timepieces. *The original Cartier strap will be available for collection from our London office.

Cartier Cartier Tank Asymétrique, Reference 4286 A pink gold asymetrical wristwatch Circa 2022 Dial: dark grey Calibre: cal. 1917 MC manual winding, 19 jewels Case: 18k pink gold, case back secured by 4 screws Case number: N°043/100 Closure: Cartier alligator strap and 18k pink gold pin buckle Size: 41 x 26 mm Signed: case, dial and movement Box: yes Papers: yes Accessories: Cartier international warranty card, instruction manual and presentation box with outer packaging The Cartier Tank Asymétrique reference 4286 is a captivating reinterpretation of one of Cartier’s most unconventional and intellectually playful designs. Originally conceived in the 1930s as part of the brand’s avant-garde “Shape” watches, the Asymétrique set itself apart through its rotated dial and skewed geometry, an intentional departure from classical symmetry meant to enhance readability while driving and to challenge traditional notions of case architecture. The reference 4286 carries forward this spirit of creative daring. Its distinctive parallelogram-shaped case, sharply angled lugs, and off-center dial orientation create a dynamic sense of movement even at rest. The bold layout, most notably the rotated numerals and repositioned crown, exemplifies Cartier’s mastery of design that is both whimsical and rigorously elegant. Produced in limited numbers and seldom encountered, the 4286 represents an important chapter in Cartier’s lineage of asymmetrical timepieces. Its blend of sculptural form, mechanical refinement, and historic design pedigree makes it especially appealing to collectors drawn to the maison’s most idiosyncratic creations. An example preserved in fine condition offers a rare chance to acquire one of Cartier’s most distinctive and artistically significant interpretations of the Tank.

Patek Philippe Patek Philippe Reference 994 A yellow gold open faced skeletonised watch Circa 2002 Dial: skeletonised Calibre: cal. 17-170 manual winding, 18 jewels Movement number: 3’076’003 Case: 18k yellow gold, snap-on sapphire display case back Size: 47 mm diameter Signed: movement Box: no Papers: no Accessories: Patek Philippe travel pouch The present reference 994 is a particularly striking example. Fully skeletonised, its movement, every bridge meticulously hand-engraved, rightfully becomes the focal point of the watch. With its inner workings on full display, the piece fosters an even deeper connection between wearer and timepiece, arguably more so than if it were fitted with a traditional dial. Remarkably, despite its near-transparent construction, the addition of blackened steel hands provides an unexpected degree of legibility. Although it shares certain design cues with reference 894, the reference 994 is, to the best of our knowledge, virtually unseen on the market. Produced in extremely small numbers, the only other example we have encountered came from the present owner’s collection. Its rarity makes this offering an exceptional opportunity to acquire a seldom-seen creation from the world-renowned manufacture Patek Philippe.

Patek Philippe Patek Philippe World Time, Reference 5131R-010 A pink gold world time wristwatch with cloisonné map of the world depicting East Asia, Oceania and the Americas Circa 2016 Dial: silvered, cloisonné enamel depicting East Asia, Oceania and the Americas Calibre: cal. 240 HU automatic winding, 33 jewels Movement number: 5’994’188 Case: 18k pink gold, screw-down sapphire crystal display case back Case number: 6’133’607 Closure: Patek Philippe alligator strap and 18k pink gold folding clasp Size: 40 mm diameter Signed: case, dial and movement Box: yes Papers: yes Accessories: Patek Philippe Certificate of Origin, instruction manual, leather bifold and presentation case with outer packaging The Patek Philippe World Time with cloisonné enamel dial stands among the manufacture’s most coveted creations, a testament to its unparalleled mastery of haute horlogerie. Introduced in 2014, the pink gold reference 5131 was produced for only three years and pays homage to the legendary reference 1415, continuing a lineage cherished by collectors worldwide. With only two to three artisans capable of crafting these dials by hand, annual production across all metals was believed to be fewer than forty pieces. Creating a cloisonné enamel dial is an exceptionally demanding art. Fine gold wires are painstakingly shaped to trace the continents, and each color is fired multiple times, a process in which many dials fail to survive. Only those that meet Patek Philippe’s exacting standards for color, clarity, and structural integrity are approved. The present example depicts Asia, Oceania, and the Americas, its vibrant composition offering a captivating display of craftsmanship. Notably, unlike its successor reference, the Patek Philippe signature is engraved on the bezel, leaving the enamel artwork entirely unobstructed.

Lord Nelson By the Officers of HMS Victory Aug 20 1805” against a light red flinqué enamel ground, the hinged back opening to reveal a fixed inner dome decoratively pierced and engraved throughout with stylised flowers, geometric motifs and with four apertures for winding, in original leather covered box with handwritten instructions diameter 120mm dial diameter 85mm Sotheby, London, 5th October 2005, Lot 184 On 20 August 1805 Nelson struck his flag at Portsmouth and went home to Merton Place, the house in Surrey he shared with his mistress Emma, Lady Hamilton. He had been at sea in HMS Victory since May 1803 and arrived home tired, anxious and frustrated that the enemy had eluded him after a frantic transatlantic pursuit. His reception in England was rapturous. He was mobbed in the streets and the great and the simply curious, including royal princes, beat a path to Merton Place which Emma, finally secure in her role as the hero’s consort, had filled with Nelson’s family. The evenings passed in happy dinner parties: the domestic turmoil that had overshadowed his last leave now no more than a distant memory. Yet the threat of the massing enemy fleet remained unresolved and by day Nelson was locked in conference at the admiralty and with ministers. On 2 September word reached London that the French and Spanish fleets had combined at Cádiz. Nelson’s inevitable recall swiftly followed. At dawn on 14 September, after an emotional farewell from Merton, he arrived back at Portsmouth. A few hours later he was pulled out to Victory to begin his final, fateful mission. The presentation of such an extraordinary watch to Nelson by the officers of Victory would have been intended to mark the end of their exceptionally long and arduous tour of duty together and, with hindsight, its date acquires a deeper resonance. Inscribed 20 August 1805, the day Nelson struck his flag and briefly returned to domestic peace, it also fell at the precise moment he was about to resume command for what his officers understood would be a major and potentially decisive campaign against the combined fleets. The gift therefore carried a double significance: both a token of gratitude for past leadership and a gesture of loyalty and confidence on the eve of their most perilous enterprise. The watch may well have been commissioned in advance of his return to shore and largely completed by that time, with the inscription added to anchor it to this significant date. Although the exact moment of presentation is not recorded, the presence of the 20 August 1805 inscription firmly associates it with Nelson’s brief interlude at Merton between sea commands and before his final battle. If completed before Trafalgar. the absence of any reference to the watch in the inventories of his possessions on Victory suggests that it remained ashore. This would be entirely in keeping with its character: a piece of exceptional decorative richness and mechanical sophistication, designed to delight through its enamelled case and charming musical performance rather than serve as a practical or highly precise instrument of timekeeping in the demanding conditions of active service. James McCabe James McCabe, founder of the renowned London watchmaking family, was born around 1748 in Ireland, probably in Lurgan near Belfast. He was active in Belfast by about 1770, where early watches signed “James McCabe, Belfast” are recorded, before moving to London early in 1775. Establishing himself first in Bells Building, Fleet Street, he moved to 34 King Street, Cheapside. By 1788 he was at 8 King Street before later settling at 97 Cornhill, Royal Exchange. McCabe quickly gained a reputation for fine watchmaking, in 1781 he was admitted as an Honorary Freeman of the Clockmakers’ Company, later serving as Senior Warden. He married Elizabeth Burn in 1779. By the 1790s the family had settled in Stoke Newington, while the business continued to flourish from Cornhill. McCabe died in 1811, leaving behind one of the most successful London watchmaking enterprises of his generation. After his death the firm was carried on by his youngest son Robert McCabe, who inherited the business on his mother’s death in 1833 and operated from 32 Cornhill, Royal Exchange. Robert died in 1860, after which his eldest son, Robert Jeremy McCabe, maintained the traditional “James McCabe, Royal Exchange” signature until winding up the business in 1879/80. For just over a century, the McCabe family established itself as one of London’s most respected horological dynasties, producing a wide range of fine watches, clocks and marine chronometers. For a history of the life and work of the McCabe family see: P. E. Hackamack, James McCabe, Antiquarian Horology, No. 3, Vol. 10, Summer 1977, pp. 308-316.

Cartier, London Cartier, London Tank Cintrée A yellow gold wristwatch Circa 1929 Dial: white Calibre: cal. LeCoultre 845 manual winding, 17 jewels Movement number: 2’079’938 Case: 18k yellow gold, case back secured by 4 screws Case number: 21’284, •381•, 27’665 Closure: 18k yellow gold Cartier folding clasp stamped 8’944 Size:  23 mm x 42 mm Signed: case, dial signed Cartier, movement signed LeCoultre Box: no Papers: no Accessories: Cartier service correspondence dated 1971/1972 In the annals of horological history, few timepieces have captured the imagination and epitomised elegance quite like the Cartier Tank Cintrée. Born from the crucible of innovation and design, this iconic watch stands as a testament to Cartier’s relentless pursuit of excellence and its ability to redefine the boundaries of watchmaking. In the wake of the First World War, a seismic shift was underway in the world of design. Inspired by the armored vehicles that roamed the battlefields, Louis Cartier conceived the Tank in 1917, a revolutionary timepiece that embodied the spirit of modernity and sophistication. Yet, it was four years later, in 1921, that the Tank Cintrée made its debut, signaling a new chapter in Cartier’s legacy. The Tank Cintrée was a triumph of form and function, marrying the ergonomic curved case profile of the Tonneau with the sleek lines of the Tank’s brancards. This fusion of design elements resulted in a watch that was both timeless and avant-garde, a symbol of Cartier’s ability to seamlessly blend tradition with innovation. The present watch, which is being offered by the family of the original owner, was made in Paris c.1929 and features a London import mark for the same year, in addition to this a London spot mark featuring dots either side can be seen on the caseback, denoting its Cartier London inventory number. The watch was then serviced by Cartier London in 1971 and is accompanied by its original service paperwork detailing the work carried out. The movement was replaced along with the dial, hence the signature London style dial, eschewing the traditional railroad minute track, it embraces a dial layout that is at once free-spirited and sophisticated. The exaggerated Roman numerals, strategically placed, evoke a sense of whimsy and elegance, inviting the wearer into a world of timeless sophistication.

Rolex Rolex Daytona, Reference 116518 A yellow gold chronograph wristwatch Circa 2010 Dial: gilt Calibre: cal. 4130 automatic winding, 44 jewels Movement number: 0’393’901 Case: 18k yellow gold, screw-down case back Case number: M’829’816 Closure: Rolex alligator strap and 18k yellow gold folding clasp Size: 40 mm diameter Signed: case, dial and movement Box: yes Papers: yes Accessories: Rolex international guarantee card and presentation box with outer packaging The Rolex Daytona reference 116518 stands as one of the most distinctive expressions of the modern Daytona line, combining the model’s storied racing heritage with the elegance and luxury of solid 18k yellow gold. Introduced alongside the steel 116520, the 116518 showcases the full potential of Rolex’s in-house chronograph movement within a more opulent and stylistically bold package. Launched in 2000, the 116518 marked a significant milestone for Rolex: it was among the first Daytonas powered by the brand’s new in-house caliber 4130, a movement engineered entirely by Rolex to improve reliability, efficiency, and serviceability. This transition represented a definitive end to the era of outsourced chronograph calibres and reaffirmed Rolex’s commitment to technical independence. While the model retains the Daytona’s hallmark features—its engraved tachymeter bezel, screw-down pushers, and instantly recognizable dial layout—the reference 116518 distinguishes itself through its luxurious case construction and versatile presentation. Offered traditionally on a leather strap and later on Rolex’s Oysterflex bracelet, the 116518 blends sport and sophistication in a way few chronographs can match. Produced for over a decade, the reference 116518 remains a highly sought-after variant within the Daytona family, appreciated for its fusion of mechanical pedigree, iconic design, and precious-metal execution.

Rolex has also long been known to use hardstones, meteorites, and even fossils for its dials. The Day-Date ref. 18238 shown here features a dial made from ammonite hardstone, an unusual material derived from fossilized mollusk organisms. This results in a truly unique dial, as each piece of ammonite hardstone is different. On this dial the 6 and 9 index is diamond-set. Inside, the watch is powered by the calibre 3155, a COSC-certified chronometer offering a reliable 48-hour power reserve, underscoring Rolex’s commitment to precision and performance.

Although the Daytona has a long and storied past, it was not until the debut of the 116520 that the model finally received a fully in-house movement. First introduced in 1963, the Daytona took its inspiration from the world of motorsport and quickly emerged as Rolex’s flagship chronograph. While not the company’s first chronograph wristwatch, it was the first to feature a tachymeter scale engraved on the bezel rather than printed along the dial’s edge, an innovation that remains central to the design today. Automatic chronograph movements arrived in 1969, yet Rolex did not adopt a self-winding caliber for the Daytona until 1988. That generation relied on a significantly reworked Zenith El Primero movement. Only in 2000 did Rolex finally unveil an entirely in-house chronograph calibre, making the reference 116520 the first Daytona powered solely by a Rolex-developed movement and signaling the end of the brand’s dependence on outsourced chronograph mechanisms. Manufactured until 2016, the 116520 preserves the timeless Daytona silhouette while introducing meaningful technical and aesthetic upgrades, most notably its durable in-house movement.

Patek Philippe Patek Philippe Reference 420 A rare stainless steel wristwatch retailed by Asprey Made in 1929 Dial: silvered, Asprey signed Calibre: 9’’’ manual winding, 18 jewels Movement number: 821’609 Case: stainless steel, snap on case back Case number: 611’453 Closure: associated strap and metal buckle Size: 22 x 37 (with lugs) mm Signed: case, movement and dial; dial further signed Asprey Box: no Papers: no Accessories: Asprey presentation box, Patek Philippe contemporary travel pouch and Extract from the Archives confirming date of sale on April 16, 1936 This exceptional Patek Philippe reference 420, manufactured in 1929, is an especially rare example of the model, crafted in stainless steel and distinguished by the Asprey signature on the dial. The collaboration between Patek Philippe and Asprey was highly selective at the time and rare examples that combine both signatures are specially coveted. Reference 420 occupies a significant place in Patek Philippe’s early wristwatch history. Produced at the turn of the 1930s, it reflects the manufacturer’s transition from traditional pocket-watchmaking to the new era of refined rectangular wristwatches shaped by Art Deco aesthetics. Most surviving examples of the reference have appeared in precious metals, particularly yellow gold, and are already considered rare. The appearance of a stainless-steel version elevates the rarity considerably, as steel was used only sparingly by Patek Philippe in this period and typically only for special orders. Early steel executions across the brand’s production are among the scarcest and most desirable configurations, making this watch an exceptional discovery. The Asprey signature adds a further layer of distinction, symbolising not only the quality of the piece but the exclusivity of the relationship between the two houses. Its original owner was a prominent British figure whose career placed him near the centre of major national and international developments of the early and mid-twentieth century, suggesting the calibre of clientele served through Asprey at the time. Although his identity cannot be publicly detailed, his status underscores the significance of the watch’s original commission. Equally remarkable is the continuity of its provenance. Retained by the family of the original owner from its purchase in 1929 until the present day, the watch has never circulated through the broader market. Such unbroken lineage offers a level of authenticity and preservation seldom encountered in early Patek Philippe wristwatches and enhances the historical value of an already rare reference. Combining early Patek Philippe design, an Asprey-signed dial, an extremely uncommon stainless-steel case, and nearly a century of single-family ownership, this reference 420 stands as an extraordinary example of early twentieth-century horology and a truly rare opportunity for collectors. Please note that Condition 12 of the Conditions of Business for Buyers is not applicable to this lot.
