Maitres du Temps – Chapter Two – Big Date Triple Calendar

In teaming three of the world’s greatest living watchmakers with one of the world’s most prestigious state-of-the-art movement manufactures, a very special timepiece is assured.

With Chapter Two, master watchmakers Mr. Daniel Roth, Mr. Roger Dubuis, and Mr. Peter Speake-Marin, went beyond “very special”: they pushed the boundaries of haute horlogerie. The resulting timepiece features an instantaneous big date triple calendar that, thanks to innovative roller indications and the unparalleled experience of the master watchmakers involved, is the world’s most legible calendar mechanical wristwatch, as well as the world’s first unabbreviated triple calendar mechanical wristwatch!

Maitres du Temps - Chapter Two

Chapter Two features central hours and minutes indicated by elegant diamond-cut, solid gold hands, sub-seconds at 6 o’clock, big date at 12 o’clock, and the day and month spelled out in full on their respective rollers. The combination of a big date and full text for the days and months confers upon Chapter Two a legibility unprecedented in a triple calendar wristwatch.

The long flowing lines of the distinctive tonneau case belie its complex architecture and sophisticated design. Myriad thoughtful details and sagacious finishes catch the light. Every aspect of the timepiece has been meticulously refined: the inside curves of the lugs match the flow of the case, ensuring absolute harmony, while the day, date, and month correctors are engraved with their functions for ease of operation. A total of six shaped, anti-reflective sapphire crystals—three on the front and three on the caseback—ensure unmatched visual access to both the indications and movement.

Turning Chapter Two over reveals a caseback unlike anything that has gone before. Two ergonomic, paddle-shaped pushers to adjust the day and month are engraved with their respective functions, and the displayed month or day on the dial side is cleverly indicated on the back through geometrically complex sapphire crystals. This is a detail that eliminates the need to turn the watch over while adjusting the roller functions and is typical of the deep level of thought Chapter Two’s experienced masters have devoted to its development and design. The date corrector, seamlessly blending with the lines to the crown, also has its function engraved on the back. As you might expect of the superstar line up that developed Chapter Two, every single detail has been carefully considered.
