W1 Evolve golf watch with GPS function, includes charging cable and instruction manual. - Model Name: W1 Evolve - Brand Name: Shot Navi - Included Items: Charging cable, instruction manual - Features: Golf watch with GPS function - Design: Round, black band The original strap broke due to the deterioration of the silicone. I will also include the broken strap. Since the original strap is no longer sold, I replaced it with a self-made one. I am selling this because I purchased a laser rangefinder and no longer use it. The battery can last for two rounds of golf. Even if left fully charged, it will not lose charge for a week. I believe there are no operational issues, but since it is a used item, please understand that it is non-refundable and non-returnable. Thank you for looking.
