Q1	What is the life of the solar cell and the rechargeable battery?
A1	Normally, the solar cell and rechargeable battery should be able to last as long as the watch. Q2 How much do I need to expose the watch to light for charging? A2 It depends on the model of your watch. Look at the back cover of your watch and find the three- or four-digit "module number". Next, click here for information about approximate required charging times for each module.
