This men's sport watch is a great companion for your hiking adventures. To use it, simply fasten the buckle clasp around your wrist. The automatic self-winding movement means it keeps ticking as you move. You can easily read the time thanks to the luminous feature, even in low light. The complete calendar and auto date functions are handy for keeping track of the day. When it comes to maintenance, the watch is water resistant up to 10 Bar, but don't leave it submerged for too long. Wipe it with a soft cloth regularly to keep it looking good. And remember, because different suppliers and brands have different size charts, always check the size carefully before choosing one that fits you perfectly.
