OVERVIEW
PRECISION IN EVERY LINK
DESIGN
A SIGNATURE TWO-COUNTER DIAL
The Master Control Chronometre Date Power Reserve is distinguished by the one-of-a-kind alliance of power reserve and date display in a refined 39mm diameter and 9.2mm thickness. Its integrated metal bracelet ensures a perfect fit, blending vintage codes into a contemporary design with sleek proportions and rich, subtle details.
A PLAY OF CONTRASTS AND CONTINUITY
Inspired by the heritage of the Futurematic, the blue-grey gradient dial finds its match in the cool lustre of the steel case. The design achieves a singular, unified look through the integrated bracelet, where alternating polished and satin-brushed links extend the architectural detail of the case across the entire wrist.
A BRACELET ECHOING THE DAUPHINE SIGNATURE
Extending seamlessly from the case to follow the curve of the wrist, the integrated bracelet creates a singular, harmonious form. Its V-shaped bevels mirror the geometry of the Dauphine hands and trapezoid indexes, creating a refined aesthetic rhythm where every link echoes the elegant character of the dial.
CALIBRE
IN-HOUSE CALIBRE 738: WHERE PRECISION MEETS EXQUISITE DECORATIONS
Reflecting the Manufacture's mastery of energy efficiency, compact volume, and chronometric performance, the automatic Calibre 738 is a testament to in-house craftsmanship. Designed, produced, decorated, and assembled entirely within our Manufacture, it offers a 70-hour power reserve and a 4 Hz frequency, all within an exceptionally thin calibre and reduced diameter.

8 UNIQUE DECORATIONS ON 241 COMPONENTS
A sapphire case-back and open-worked 22K pink gold mass reveal a finely finished movement with Côtes de Genève, sunk rubies, polished grey screws, and bevelling among other HPG seal decorative finishes.
HIGH PRECISION GUARANTEE SEAL
THE SEAL OF ENDURING RELIABILITY
The High-Precision Guarantee (HPG) rigorously tests calibres and cased watches against daily wear cycles over 3 days that cover two typical weekdays and one weekend day, simulating wrist positions, pressure, temperature variations, and shocks.
BEYOND RELIABILITY: DECORATIVE EXCELLENCE
The HPG label ensures that each calibre component receives meticulous decoration from a range of eight decorative techniques: circular graining, Côtes de Genève, circular smoothing, burnishing, polished screw-heads, linear smoothing, sinked rubies, and bevelling.
HERITAGE
EIGHT DECADES OF INNOVATION UNDER THE MASTER NAME
Born from the quest to create “the ideal contemporary watch” blending high performance, distinctive design, and ergonomic comfort, the Master Control Chronometre synthesizes eight decades of Master creations.
