SERICA’S DIVING CHRONOMETER
CHRONOMETER CERTIFIED CALIBER
THE REFERENCE 5303 COSC INTRODUCES SERICA’S GRAND CHRONOMÈTRE CERTIFICATION.
EQUIPPED WITH THE M100 CALIBER CERTIFIED BY THE OFFICIAL SWISS CHRONOMETER CONTROL AUTHORITY. ONCE ASSEMBLED, OUR GRAND CHRONOMÈTRE WATCHES UNDERGO A SERIES OF TESTS TO CHECK THE PRECISION, POWER RESERVE AND SHOCK RESISTANCE OF EACH INDIVIDUAL PART.
ANOTHER STEP FORWARD IN THE QUEST FOR OUR IDEALS.
ANTI-MAGNETIC CASE CONSTRUCTION
WE BUILT A THREE-PART CAGE TO REDIRECT THE MAGNETIC FIELDS.
THIS IMPROVES THE MAGNETIC RESISTANCE OF THE REFERENCE 5303 BY MORE THAN 10 TIMES THE SWISS STANDARD, FROM 4,800 A/M TO OVER 50,000 A/M.
