Perpetual Calendar

The Perpetual Calendar Revolution: Crown-Only Adjustment via Patented Calibre 7138

The mechanical epicenter of this highly complex wristwatch houses the manufacture’s next-generation in-house self-winding mechanism, Calibre 7138. Built with absolute mastery from 420 individual componentsand incorporating 41 jewels, this movement beats at a frequency of 4 Hz (28,800 vph) and delivers a 55-hour power reserve, all contained within a highly streamlined layout thickness of just 4.1 mm. Representing a massive technical leap in calendar user experience, Calibre 7138 relies on three patented internal mechanisms that allow all perpetual calendar indications to be adjusted solely via the winding crown. This complete innovation removes the traditional necessity for corrective push-buttons on the caseband or the use of any additional tools. The movement drives central Hours and Minutes alongside a grand multi-display calendar comprising Day, Date, Month, Leap Year indicators, a dedicated outer ring for Week Indication, and an high-precision Astronomical Moon cycle.

Unified Tone-on-Tone Legibility via the Green Embossed Dial Face

The dial composition relies on a vibrant green embossed face that acts as a stunning canvas, capturing incoming light with incredible multi-dimensional nuance. Anchoring an elegant tone-on-tone presentation, the calendar display utilizes color-matched green subdials that sit in perfect harmony, tightly framed by a matching green inner bezel. For optimal legibility under any ambient lighting conditions, the applied hour-markers and central alpha hands are forged from premium 18-carat pink gold and meticulously filled with a luminescent coating. This visual execution introduces a warm, luxurious contrast that mirrors the physical metal shell while ensuring outstanding data readability.

Refined 38 mm Multi-Planar Geometry & Premium Alligator Finish

The multi-layered case profile measures an exceptionally balanced 38 mm in diameter and a highly streamlined thickness of just 10 mm, providing enhanced ergonomics and sitting comfortably on the wrist. Forged entirely from premium solid 18-carat pink gold, the case showcases alternating hand-polished bevels and satin-brushed planes that accent the complex geometry of the signature Code 11.59 layout—completely uninterrupted by calendar correction slots. Both the front face and the exhibition caseback are protected by an anti-reflective double glareproofed sapphire crystal, exposing the hand-finished movement parts from behind. Delivering a classic haute horlogerie lifestyle look, the watch comes mounted on an integrated green alligator leather strap and is secured by an 18-carat pink gold AP folding clasp, maintaining a technical water resistance of 30 m.
