With Patek Philippe Extract from the Archives confirming production of the present watch with silvered dial and raised steel Breguet numerals in 1942 and its subsequent sale on 16 June 1948.
The watch offered here for sale combines several highly sought after features, the rare stainless steel case, the much liked Breguet numerals and the excellent overall condition. Research has resulted in the discovery that it is in fact the only example of a reference 687 in steel and with Breguet numerals, confirmed by the Extract, to appear in public to date.
Launched in the late 1930s, reference 687 was made in an extremely small series only, comprising 12 examples in yellow gold and 12 examples in steel.
