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.

Since its debut in 1993, the Seamaster Diver 300M has stood as one of Omega’s most celebrated collections, blending professional-grade diving capabilities with refined design. Over the decades, it has evolved through numerous materials and styles while remaining faithful to its ocean-inspired DNA.

The collection welcomes two striking editions, each crafted from one of Omega’s proprietary gold alloys. One is made from 18K Sedna Gold, the other from rich 18K Moonshine Gold. Both retain the unidirectional rotating bezel, screw-in crown, and helium escape valve at 10 o’clock. Measuring 42 mm in diameter, 13.7 mm in thickness, and just under 50 mm lug-to-lug, each case offers the same 300-metre water resistance.

The Sedna Gold edition stands out with its white ceramic dial, enhanced by laser-engraved waves, a date window at 6 o’clock, and luminous skeleton hands and indices in matching Sedna Gold. Surrounding the dial is a gold bezel featuring a diving scale over a finely grained background. The Moonshine Gold model opts for a more classic tone with a polished black ceramic dial bearing the same engraved wave motif, framed by a black ceramic bezel with a Ceragold diving scale that allows for the fusion of gold into ceramic watch bezels. Both dials are complemented by white Super-LumiNova hands and indices for optimal legibility.

Inside each watch beats the Co-Axial Master Chronometer calibre 8801, an automatic movement running at 25,200 vph (3.5 Hz), equipped with a co-axial escapement and offering a 55-hour power reserve. It is built to resist magnetic fields up to 15,000 gauss.

The Sedna Gold version is paired with a brown rubber strap and matching gold pin buckle, while the Moonshine Gold edition comes with a black rubber strap secured by a Moonshine Gold pin buckle. Both watches are part of the permanent collection. Pricing is set at EUR 32,900 / AED 132,450 for the Sedna Gold model and EUR 32,200 / AED 129,950 for the Moonshine Gold version.
