Patek Philippe Ref. 725 Perpetual Calendar Pocket Watch
by Terry Betteridge on July 22nd, 2011
While big timepieces are the style today, some watches capture the hearts of generation after generation of collectors.
Our Patek Philippe astronomical, perpetual calendar is a “best of best”: where you’ve surpassed the end of the scale to measure greatness. In a format this grand, all the months of the leap year cycle are bold; the enamel night sky and golden moon vivid.
In pristine condition from 1951, one of Patek’s best is ready to be engraved for the first time ever.
Seen at right: Patek Philippe perpetual calendar keyless, open-faced pocket watch (ref. 725), featuring a m. 17”’-170, rhodium-plated with “fausses-côtes” decoration, 18 jewels, straight line lever escapement, adjusted for heat, cold, isochronism and 5 positions, blued steel Breguet balance spring with swan neck regulator; three-body, “variée carrure plate” with a concave bezel; silver dial with applied gold Arabic numerals and gold “feuille” hands; perpetual calendar complication with sub-dials for days-of-the-week, month with leap year indication, date and seconds with moon-phase display aperture; and 46mm, 18k yellow gold case with a polished gold case back.
