Patek Philippe Keyless Five-Minute Repeating Single-Button Chronograph Pocket Watch

Partially verified

This Patek Philippe & Co. pocket watch, numbered 65435 and dated 1882, is a keyless five-minute repeating chronograph. It is constructed with an 18K pink gold four-body "bassine et filets" case, which features a polished finish, a hinged back cover engraved with a coat of arms and initials, and a hinged gold cuvette. The mechanism is a 19-ligne movement finished with rhodium plating and "fausses cotes" decoration. It is fully jeweled and equipped with a counterpoised straight-line lever escapement, a bimetallic compensation balance, and a blued steel Breguet balance spring. The repeating function operates via two hammers on two gongs, activated by a slide in the case band. The white enamel dial features radial Roman numerals and an outer track for fifth-second divisions. The watch is accompanied by an Extract from the Archives and remains in its original fitted Patek Philippe case.

Object description

Case and Dial

The watch is housed in a four-body 'bassine et filets' case crafted from 18K pink gold. The case has a polished finish and features a hinged back cover adorned with an engraved coat of arms and initials. A chronograph safety slide is integrated into the band, while a hinged gold cuvette protects the internal movement.

The white enamel dial displays radial Roman numerals for the hours. The perimeter features an outer 1/5th seconds division track, complemented by Arabic numerals at five-minute and five-second intervals. A concentric minute track is present, alongside a subsidiary seconds dial. The time is indicated by blued steel 'spade' hands.
