Dial
A black double-layered sunray dial with dimensional construction
The watch features a black double-layered dial with a refined sunray finish. Composed of two separate levels layered together, the construction creates genuine depth and dimensionality. The sunray brushing enhances the vertical design, producing a dynamic interplay of light and shadow while reinforcing the watch’s graphic precision.

Case
Masterlink: a new thinner squared case
The Masterlink case comes from the ‘Maestro’ one with the ‘smile’ at 6 o'clock, with some small adjustments: while the Maestro is designed around a rectangle, the Masterlink is based on a square. Consequently, the proportions are therefore more contained. A particularly challenging and specific development pertains to the crown: despite the case’s slimness (7.99 mm), it is screw-down. The Maison overcame the challenge to offer a 100 metres-waterproof watch without adding even a tenth of a millimeter to the height of the case.

A rarity for integrated bracelets
Bracelet's hidden screws and push-buttons
The bracelet's links are held together by a hidden construction, visible only on the back of the watch with the aid of a magnifying glass. The butterfly-type clasp is also concealed, and its metal components are designed for comfort on the wrist and softness to the touch. In the same vein, the push-buttons to open it are discreetly nestled within, ensuring the design’s fluidity sweeps smoothly over the unified case and bracelet.

The last integrated asymmetric bracelet designed by Mr. Genta
The Sarawak: Masterlink's origins
In 2007, Gérald Charles Genta designed the Maison's first integrated bracelet watch as an exclusive piece for the Royal family of Sarawak, a Malaysian state. The predecessor of the Masterlink featured a full pavé set bracelet and case in round diamonds and baguette rubies, carrying the DNA of high-end gem setting which now is signature to the Maison.
