Стандарт DIN 8319. Подробнее тут
В принципе, то же, что и COSC, только в сборе и стоп-секунда должна быть. |
ага, спасибо
The DIN 8319 procedure requires 15 days of testing, in the same positions as for COSC (dial up, dial down, crown left, crown on top, crown below), with an average daily rate variation between -4 and +6 seconds.
Watches must have the stop-second function, and they are tested while completely assembled in their cases.
