This men's skull hole sports wristwatch is a great accessory. To use it, simply fasten the buckle clasp around your wrist. It's water - resistant up to 3Bar, so you can wear it in light rain or while washing your hands, but avoid submerging it deeply. The luminous hands make it easy to read the time in low - light conditions. For maintenance, clean the watch regularly with a soft, dry cloth. Avoid exposing it to extreme temperatures or harsh chemicals. Keep it in the paper box when not in use to protect it from scratches.
