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.

Grand Feu Enamel

Grand Feu Enamel

Is a specialized finishing technique for watch dials, involving the heating of silica powder and other compounds on a metal base at extremely high temperatures in consecutive layers. The compounds melt and fuse together to create a glassy surface. This type of finishing is done in multiple layers, with each layer individually heated in the furnace, which poses a risk to previously applied and heated layers.

The "Grand Feu Enamel" technique is known for its high level of difficulty and a high failure rate. Maintaining a delicate balance between temperature and timing throughout the process is crucial to achieve the desired result. Each layer contributes to determining the thickness of the glass coating and allows for the integration of multiple colors.
