Mechanics in its purest form
B03
Grade 5 titanium has that rare quality of giving a large watch the lightness of an almost immaterial object. 43.8mm on the wrist, yet you almost forget it's there. The rhodium treatment on the bridges reveals the movement in a soft and precise light, which subtly changes depending on the angle, the time, the day. A watch that you look at differently every morning.

43.8mm | Grade 5 titanium
ON THE WRIST
The B03 does not go unnoticed.
Its presence on the wrist is immediate, luminous, assertive. And yet, it surprises. The grade five titanium gives it an unexpected lightness. A seductive paradox that can only truly be understood by wearing it.

Swiss Made · Design DONE
THE MOVEMENT
The ETA 6497-1 calibre, commonly known as the "Unitas," is one of the most reliable and recognized mechanical movements in the watchmaking world. Its slow frequency of 2.5 Hz allows one to contemplate the balance wheel oscillating at an almost perceptible rhythm. Winding it every morning means embracing a fragment of its mechanics. Giving it the energy for the day. On the B03, the bridges have been completely redesigned and rhodium-plated. A subtle interplay of grained and polished surfaces that interacts with light with particular clarity.
QUALITY CONTROL
BEFORE ASSEMBLY
Before being assembled, the caliber bridges go through a meticulous decoration and finishing process. Each grained surface, each polished flat, invisible work that the watch on the wrist only hints at.

DESIGN
FROM DRAWING TO REALITY
Behind each B03, dozens of CAD iterations before arriving at this result. The technical drawing does not lie, each dimension is the result of a precise compromise between the constraint of the caliber and the visual balance on the wrist.
