 asterworks of Time Part III\, 3-16 June 2020\, lot 73.\n\nThe display of t
 ime through apertures cut into the front of a watch case has a long and ri
 ch history\, though it became especially fashionable during the Art Deco p
 eriod. This popularity was due in part to the novel way the format could b
 e integrated into and complement the design of the fine\, slim dress watch
 es of the era. Although such “window” forms of indication were equally
  well suited to calendar displays\, jump hour watches combined with calend
 ars are rare\, and those incorporating a perpetual calendar are rarer stil
 l. This is almost certainly attributable to the high cost of production. T
 o illustrate this point\, the present watch was priced at 24\,000 Francs 
 — three times the cost of a white gold wandering jump hour watch by Breg
 uet sold in the same year\, 1927.\n\nCortlandt Bishop (1870–1935) was a 
 prominent New Yorker known for his varied interests\, including aviation\,
  automobiles\, and art. His business activities were equally diverse\, ran
 ging from a real estate portfolio with prime holdings on Sixth Avenue in M
 anhattan to his ownership of America’s largest auction house\, the Ameri
 can Art Association–Anderson Galleries\, the predecessor of Sotheby’s.
  Under Bishop’s stewardship\, Major Hiram H. Parke and Otto Bernet were 
 appointed to run the firm.\n\nAfter Bishop’s death in 1935\, Parke and B
 ernet left to establish Parke-Bernet Galleries. In 1938 Parke-Bernet purch
 ased the American Art Association–Anderson Galleries from Bishop’s est
 ate\, and in 1968 Sotheby’s acquired Parke-Bernet\, becoming Sotheby Par
 ke-Bernet.\n\nA very similar example\, numbered 1622 and sold in 1930\, wa
 s offered at Chayette\, 13 June 1984\, lot 91\, reappearing again at Chris
 tie’s Geneva\, 10 November 2014\, lot 390.
