OVERFLY TEVISE Automatic Skeleton Mechanical Dial Luxury Analog Watch - For Men T820

•This is an Automatic watch and runs on the kinetic energy generated by the movement of your hand. When you wear the watch for the first time, you need to wind up the watch 20 To 30 times at least in clockwise rotation. THIS IS VERY IMPORTANT •Now your watch will get the initial charge and you can set the time and date normally and start wearing your watch. •You need to wear the watch at least 8 hours during the day as it keeps getting charged when you move your arm…if you feel like you can take it out during the night while sleeping and wear it in the morning. If you have worn it for minimum 8 hours then it would still have the charge to keep running till the morning. • When you do not wear it long enough or it stays idle, the energy of the watch would not be enough to keep it running. It will start slowing down and eventually stop. When this happens you again wind it up 20 To 30 times and your watch would get charged and you can continue to wear it. As this is an Automatic movement watch, there is no battery inside it…hence it can run for a long time and does not need any battery change.
