The Twenty~4 collection, long associated with understated elegance and daily versatility, reaches a new milestone with the introduction of its first complication — a perpetual calendar. Ref. 7340/1R-001 and its counterpart with a sunburst olive green dial, Ref. 7340/1R-010, bring this celebrated calendar function into the Twenty~4 line for the first time, without compromising the collection’s refined proportions or signature visual clarity.

This release marks two firsts: not only is this the first perpetual calendar within the Twenty~4 family, it’s also the first round Twenty~4 model without gem-setting. In its place, the watches offer a more nuanced approach to detail, from dial textures to hand finishes, in a package that feels both contemporary and confident.

The 36mm rose gold case is fully polished, with a low profile (9.95mm) made possible by the ultra-thin movement inside. The case retains the gentle taper and balanced proportions that have made the Twenty~4 a versatile choice, whether worn casually or more formally. The crown is adorned with the Calatrava cross — a subtle but deliberate signal of the mechanical sophistication within.

Two dial executions are offered. Ref. 7340/1R-001 features a silvery dial with a vertical and horizontal satin-brushed finish, reminiscent of shantung silk. Ref. 7340/1R-010 presents a sunburst olive green dial, a tone that feels fresh yet grounded. In both versions, applied Arabic numerals and rounded baton-style hands in rose gold are filled with luminescent coating for visibility in varying light. The displays — for day, date, month, leap year, 24-hour time, and moon phase — are arranged in four subdials, creating a balanced and recognisable perpetual calendar layout.

At the core of both models is the self-winding calibre 240 Q — a movement with a 22K gold micro-rotor that allows for a slim case profile. The perpetual calendar mechanism accounts for the varying lengths of months, including leap years, with accuracy requiring no correction until the year 2100. The moonphase display, as always, is calibrated for long-term precision, deviating by a single day only once every 122 years.

Each watch is fitted with a fully polished rose gold bracelet, featuring a central link design with gently curved edges for comfort. The clasp — a patented fold-over system with four independent catches — ensures both security and ease of use. While visually seamless, it’s engineered for modern wearability and discreet functionality.

The Ref. 7340/1R-001 and 7340/1R-010 bring real technical weight to the Twenty~4 line without disrupting its design language. The perpetual calendar sits naturally within the case and bracelet architecture, and the execution feels considered from both a mechanical and aesthetic standpoint. It’s a clear evolution—measured, confident, and built with long-term relevance in mind.
