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.

Jaeger-LeCoultre has long been celebrated for its mastery of fine watchmaking, a legacy built over nearly two centuries of mechanical innovation. This expertise shaped the creation of the Master Ultra Thin collection, a modern expression of refined dress watchmaking defined by its slim profiles, classical proportions, and exceptional mechanical precision. Today, the brand introduces a grained copper-coloured dial to two of its cornerstone models: the Master Ultra Thin Date and the Master Ultra Thin Moon.

Both models are presented in polished stainless steel cases measuring 39 mm in diameter. The Master Ultra Thin Date has a thickness of 7.9 mm, while the Master Ultra Thin Moon stands slightly taller at 9.3 mm. A transparent sapphire caseback reveals the movements, and both watches offer a water-resistance rating of 50 meters.

The new grained copper dial brings a warm, contemporary character to the Master Ultra Thin line. Its subtle texture interacts beautifully with the light, shifting from a soft pastel copper hue to a deeper tone depending on the angle. The elongated trapezoid indices and Dauphine hands maintain the collection’s signature aesthetic.

On the Master Ultra Thin Date, a white date disc appears in a rectangular window at 6 o’clock. The Master Ultra Thin Moon features a moon-phase display surrounded by a circular date ring, with a silver moon set against a deep blue starry sky.

The Master Ultra Thin Date is powered by the self-winding Calibre 899, while the Master Ultra Thin Moon is equipped with Calibre 925. Both movements are produced in-house and deliver a power reserve of 70 hours. Through the sapphire caseback, the refined decoration is clearly visible, including Côtes de Genève, bevelled bridges, blued screws, and an openworked pink gold rotor.

Each model is paired with a brown alligator leather strap equipped with an interchangeable system and secured with a stainless steel folding clasp. Both are limited editions of 800 pieces each. The Master Ultra Thin Date is priced at EUR 10,400 (approximately AED 44,300), while the Master Ultra Thin Moon retails for EUR 12,600 (approximately AED 53,700).
