Setup, Compatibility & Care
To set the time and date, pull the crown out to the first position to adjust the date, and to the second position to adjust the hour and minute hands. Since the Hydromatic features an open case back and side apertures, avoid exposing the watch to harsh chemicals or abrasive surfaces that could scratch the exposed glass. While it is water-resistant up to 50 meters, always ensure the crown is fully pushed in before contact with moisture. To clean, use a soft, dry microfiber cloth to wipe down the casing and crystal; avoid using ultrasonic cleaners or heavy water pressure.
