The accuracy of caliber NH35/4R35 is between +45 / -35 seconds per day. This rating is based on normal daily wear on the wrist in temperatures between 5 ºC and 35 ºC. When testing your watch for timekeeping, make sure it is fully wound.
This watch is stunning, far nicer in person than any picture could capture and it runs excellent.
