Gently pull the crown out to the first position to set the date. Pull it to the second position to set the time. Push the crown back in fully to ensure water resistance.

The watch has a water resistance of 100 meters (10 ATM), suitable for splashes and brief immersion. It is not recommended for diving or prolonged swimming.

Care for the leather strap by avoiding excessive moisture and harsh chemicals. Clean with a soft, dry cloth. Natural aging is part of its character.

The 45 mm refers to the diameter of the watch case, measured across the widest point.

Yes, the strap can be replaced. It uses a standard lug width and a specific buckle reference, allowing for aftermarket or official replacement straps.

Manually wind the crown by rotating it clockwise 30-40 times while it is in the closed position. If the issue persists, ensure the watch is worn regularly as the automatic movement relies on wrist motion.

Ensure the chronograph pusher buttons are fully engaged when pressed. If the reset issue continues, it may require professional servicing to recalibrate the chronograph mechanism.

The superluminova treatment provides luminescence. Ensure the watch has been exposed to light for a period to 'charge' the luminous material. If luminescence is weak, the material may need servicing.

Genuine leather straps often require a break-in period. Wear the watch consistently to allow the strap to conform to your wrist. Avoid exposing the leather to excessive moisture.
