Reference 57260 :
Beyond the limits of mechanical watchmaking
Born of eight years of research and the vision of three Master Watchmakers, 57 complications converge in a single, unique masterpiece. Making it the most complicated watch ever built at the time.
A new architecture of time
Conceived as an absolute horological statement, the Reference 57260 embodies mastery at its most ambitious. Featuring a double dial, over 2,800 components and 242 jewels, each function was recalculated, redesigned and reinterpreted to form a perfectly harmonious whole.
Made using the classic principles of watchmaking along with resolutely 21st century thinking, this watch was an entirely original creation exhibiting a total of 57 complications, several of which were entirely new and unique at the time.
More than a sum of complications, it represents a new grammar of time.
The Hebraic Perpetual Calendar
Long considered mechanically unattainable, the Hebraic perpetual calendar translates the complexity of lunar and solar cycles into a fully operational mechanism of extraordinary precision.
Based on the 19-year Metonic cycle, integrating embolismic months and displaying the sacred date of Yom Kippur indicated in the Gregorian calendar alongside the secular Hebrew year, this achievement stands as one of the most significant contributions to contemporary mechanical watchmaking.
The double Retrograde Rattrapante Chronograph
For the first time in watchmaking history, two chronograph hands operate in unison without ever meeting. Each follows its own retrograde arc on opposing sides of the dial, creating a visually dramatic and mechanically revolutionary interpretation of the split-seconds chronograph.
Entirely developed in-house, this architecture required the invention of a completely new chronograph mecanism.
Westminster Chiming, Alarm and Special Night-Silence Feature
The watch offers Grande Sonnerie and Petite Sonnerie striking modes, faithfully reproducing the cadence of the "Big Ben", the clock of the Palace of Westminster. At its heart lies an integrated alarm system with its own power reserve, capable of sounding either a traditional single-gong alarm or a full Westminster carillon in Grande or Petite Sonnerie mode.
It also introduces a remarkable innovation: an automatically activated Night Silence function, suspending the chiming between 10 p.m. and 8 a.m. without requiring manual intervention.
A rare equilibrium between acoustic mastery, mechanical ingenuity and considered design.
Celestial Indications and Armillary Sphere Tourbillon
The second dial presents the night sky visible from the owner’s home city, alongside sidereal time, the equation of time, sunrise and sunset indications, and a dual Gregorian and ISO 8601 perpetual calendar with retrograde date. A 12-hour second time zone, paired with a digital world-time display, completes this astronomical ensemble.
At its centre, the armillary sphere tourbillon rotates simultaneously in three planes, revealing the Maltese Cross every 15 seconds, a poetic yet precise interpretation of the cosmos.
