What are SERICA's commitments regarding chronometer certification?Updated 5 days ago

Chronometer certification ensures that the movement in your watch meets the standards of a norm determined by the International Organization for Standardization (ISO).

SERICA conducts additional tests once the watch is assembled (before sale or in after-sales service). A rate accuracy average in 6 positions on a calibrated testing device is performed for each watch to ensure that the movement of your watch is always statically within the tolerances of [-4:+6] seconds/day.
