Patek Philippe Calatrava 3509A
More actions
The Patek Philippe Calatrava 3509A was produced from 1963 to 1968 alongside the far more common reference 3466, distinguished by a 33 mm steel case with a screw-down caseback, an unusual departure for Patek's dress-watch line, whose Calatravas otherwise favored a snap-on back that never fully sealed against moisture. (Collectability) The steel execution, cased as the "A" ("acier") variant of the reference against the gold 3509, is believed to survive in only a few hundred examples, its plain dial carrying raised baton or Breguet numerals depending on execution over the manual-wind caliber 23-300, an 18-jewel movement typical of Patek's simplest 1960s dress calibers. (The Keystone) The reference sits in the Calatrava's postwar middle period, after the archetypal reference 96 and before the line's 1970s and 1980s references widened the case and complicated the dial.
