Thank you for viewing. I am selling this because I used to use it, but I stopped using it after I started wearing a wristwatch. It can withstand sweat and water pressure from washing your face. The tip of the chain is a pin badge, so it can be attached to clothing or bags. It is currently discontinued. * The battery has stopped. Replacement is required. Color: Gold Windshield: Mineral glass Case material: Stainless steel Case diameter: Approximately 31mm Case thickness: Approximately 9mm Other functions: Pulse meter Movement: Quartz Water resistance: 3 atmospheres Dial color...
