PERPETUAL EVOLUTION
Our professional dive watch is back, with some big surprises. The new COSC M100 caliber and new non-magnetic soft iron construction.
Its aesthetics, materials and proportions that we love so much remain unchanged.
ALTERNATE FINISHES
The finish of the reference 5303 COSC constantly blends polished and brushed surfaces, whether circular, linear, or sunray.
Craftsmanship that reveals its construction and gives life to its proportions.
EASY TO READ
As any true dive watch should be, the Serica 5303 COSC is extremely easy to read underwater thanks to its large and luminescent indexes.
Thick layers of applied Super-Luminova guarantee a strong and long-lasting glow.
HIGH-END MATERIALS
To sapphire, enamel, and 316L stainless steel, we have now added engraved polished high-density ceramic to the rotating bezel.
A virtually scratch-proof material that will retain its contrast and original aspect.
