Maîtres du Temps Chapter Two – Big Date Triple Calendar

After Chapter One, Maîtres du Temps presents a new addition “Chapter Two” to its line of extra ordinary high end time pieces. The new timepiece was created in association with  three of the world’s greatest living watchmakers – Mr. Daniel Roth, Mr. Roger Dubuis, and Mr. Peter Speake-Marin – and one of the world’s most prestigious movement manufactures.  Equipped with a self-winding movement, the Maîtres du Temps Chapter Two 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.

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.
Chapter Two’s technically groundbreaking movement was developed in close collaboration by its highly experienced master watchmakers and was extensively developed, tested, refined, and decorated until Chapter Two satisfied their most exigent standards. In particular, the mechanism for driving the rollers demanded significant technical and inventive reflection to obtain the most efficient and reliable system possible—the fact that the big date and both rollers change instantaneously bears testament to the success of their innovative design and high-precision manufacture.

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. 

Looking through the octagon-shaped sapphire crystal of the display back into the beautifully decorated movement within, the eye is immediately drawn to the richly engraved symbolically goblet-shaped rotor of the automatic winding system. The intricate panier guilloche decorating the rotor’s center provides a noble counterpoint to the text around the rotor’s periphery that reads Masters and Their Craft—A Lifelong Pursuit of Excellence.

The richly hand-decorated movement features a veritable melody of harmonious fine finishing, from the sun-ray Côtes de Genève on the bridges with their perfectly beveled edges, to the helical spirals and perlage on the mainplate, to the mirror-polished screw heads.
