Not all Fossil watches carry the same battery, so you'll need to verify the make of your watch and see what battery type is compatible. Replacing batteries yourself can be tricky and could harm the watch internally. Your best bet is to send the watch into Fossil for a replacement. It will cost you $18.50, which includes return shipping and handling fee.
A 371 watch battery
Yes, the actual time keeping part is electronic. Only the second hand is wound.
To change the battery in a Fossil Arkitekt FS4048 watch, you will need a compatible replacement battery, a small screwdriver, and a case back opener tool. Carefully remove the old battery using the tools, and replace it with the new battery ensuring the correct polarity. Finally, reassemble the watch by securing the case back properly. If you are unsure, it may be best to have it done by a professional watch technician.
The fossil blue watch series has a replaceable battery should the battery die. The back is threaded to allow access to the battery. The new battery would be installed.

Fossil watches are harder than most to replace the battery on as the battery compartment is sealed and pressurized. In order to change the battery one must remove the back plate from the watch then remove the nylon cover beneath it. Press the spring that holds the battery in place to release it.

It requires a watch battery, but there will be one in the watch. You'll only have to worry about replacement when the time comes.
