Realized to celebrate the twentieth anniversary of Diagono, the Diagono Calibro 303 perfectly represents the new trend adopted by this collection.
Its case, comprises a remarkable 75 different elements and is the fruit of a lengthy design period. It is characterized by a new bezel with a flat, white gold profile. A veritable monument to watchmaking know-how, the Calibro 303 features extreme attention to detail, such as the anti-skid surface with vertical lines on the two chronographic buttons, the double matte and glossy finish of the case, and the embracing design of the winding crown guard.
The new dial is realized on three levels with different types of finishing: a metal base with Satinée Soleil decoration; an upper anthracite level with vertical treatment; supplemental counters finished with circular trim; faceted, luminescent, and hand-applied indices
A BVL 303 caliber movement is visible through the sapphire crystal window on the back. The number 303 indicates the number of components comprising the movement: exactly 303.
This handmade, self-winding chronograph has an especially thin profile that renders the watch extremely comfortable to wear. Its development requires 3,520 hours of work and the use of 10 different materials. The base plate alone, which is the skeleton of the movement, requires 250 different manual finishing and polishing operations. The sophisticated system for distributing the chronographic functions is technologically significant, being realized with a column wheel, while a vertically mounted pinion prevents jumping during start-up, stopping, and resetting of the chronograph.
Every watch is tested for water resistance to a depth of 100 meters, offering the end user the most severe guarantee of quality.
