CONSTANTLY MOVING FORWARD
The new SERICA 5303 COSC, offers a new chronometer certified calibre and a soft-iron antimagnetic inner construction.
It also introduces our « Grand Chronomètre » certification.
Its beloved aesthetics, harmonious proportions and carefully chosen materials, of course, remain unchanged.
OFFICIALLY CERTIFIED
Working closely with the Soprod manufacture and the official Swiss Chronometer Testing Institute (COSC), every SERICA 5303 Diving Chronometer now proudly carries the prestigious chronometer certification.
A true testament to Swiss mechanical precision, honed over 50 years, this new certification elevates our commitment to excellence, ensuring that every SERICA watch out of production meets the highest standards of accuracy and performance.
FIGHTING MAGNETISM
There are two ways of preventing magnetic fields from affecting the accuracy of a mechanical watch.
The most recent evolution of the early 2000s consists of manufacturing a balance spring made out of silicon.
The old-fashioned way, made possible by transitioning to the thinner calibre M100, consists of building a soft-iron cage around the movement to redirect magnetic fields.
This cage, composed of three parts as depicted above, improves the current Swiss standard in magnetic resistance by 10 times, upgrading the usual 4,800 A/M to above 50,000 A/M.
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.
