45MM A clean watch, nothing wrong with it. I tried it for half an hour and didn't like it. 200 mAh, lasts about three days. It has location tracking, payment options (PayPal, etc.), a calculator, and a game. You can set wallpapers with your own pictures or any picture from your gallery. You can make calls and answer them. These are most of the features. Price: 60. I bought it for 70. Hand-to-hand delivery. Case Size: 45mm Condition: New Connectivity: GPS Color: Silver
