Gerald Charles Unveils Its Most Complex Timepiece, The Masterlink Perpetual Calendar

Gerald Charles, the independent Swiss watchmaking Maison founded by the great Mr. Gérald Charles Genta, unveils its most complicated watch since its reestablishment less than a decade ago. The Masterlink Perpetual Calendar, developed entirely in-house, marks a new chapter for the young and ambitious Maison as it continues to expand its repertoire of poetic complications.

In keeping with Gerald Charles’s “No Compromise” watchmaking philosophy, established by Mr. Genta more than a quarter of a century ago, the Masterlink Perpetual Calendar introduces an in-house, asymmetrical, automatic perpetual calendar calibre with a three-counter display.

COSC

Contrôle Officiel Suisse des Chronomètres, is an independent Swiss organization responsible for certifying the performance and accuracy of mechanical watches through a series of tests on watch movements. It is considered one of the highest standards in the watch industry for measuring the performance and accuracy of watches.

The watch movement undergoes a series of rigorous tests and measurements under various temperature conditions over a specified period, typically up to 15 days. These tests evaluate the performance and accuracy of the watch.

To achieve the COSC certification, the average daily rate of the watch must fall within a specific range of -4 to +6 seconds per day. This means that the watch should not deviate more than -4 to +6 seconds from the exact time over a 24-hour period. Additionally, the movement must meet specific criteria for accuracy, stability, and reliability.
