Water Resistance (50M):
This watch is designed with 50-meter water resistance, making it suitable for daily use and various water activities. It can withstand:

Maintenance
Cleaning:
Wipe the watch case and strap with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by thorough drying. Do not use chemical cleaners.
