Patek Philippe Minute-Repeating Chronograph Pocket Watch

Partially verified

This Patek, Philippe & Cie. minute-repeating chronograph pocket watch was manufactured in 1910 and sold on November 23rd, 1931. The 52 mm diameter timepiece features an 18K yellow gold four-body 'bassine' case, with a hinged gold cuvette and an engraved monogram on the back cover. The watch is powered by a rhodium-plated 19''' movement with fausses cotes decoration and 35 jewels, utilizing a straight-line calibrated lever escapement, a bimetallic compensation balance, and a swan-neck regulator. The white enamel dial is accented with Breguet numerals and blued steel Breguet hands, accompanied by outer minute and fifth-of-a-second chronograph divisions. A safety bolt for the chronograph is integrated into the case band at 11 o'clock. The watch comes with an Extract from the Archives confirming the original dial configuration. It includes complex repeating functions on gongs, activated by a slide mechanism on the case band.

Object description

Case and Dial

The timepiece is housed in a large, four-body 'bassine' case constructed from 18K yellow gold. The exterior back is polished and features an offset engraved monogram identified as 'EG'. A hinged gold cuvette protects the movement from dust and environmental debris.

The white enamel dial displays a classic aesthetic, featuring Breguet-style numerals. The perimeter of the dial provides functional utility for the chronograph through outer minute and fifth-of-a-second divisions, supplemented by five-minute Arabic numeral markers. The time is indicated via blued steel Breguet-style hands. The dial configuration is officially confirmed as original by the company's Extract from the Archives.
