Fossil replaces batteries for a fee, but it is cheaper to buy a replacement battery for your Fossil F2 watch and change it yourself. Watch battery replacement does not require specialty knowledge, although some general technical skill is required.

Things You'll Need

Insert the flat-head screwdriver into the hole in the back of the watch.

Turn the cover to the left until it comes loose.

Lift the seal that covers the battery using the tip of the screw driver.

Apply light pressure to the spring attached to the battery latch. This releases the latch to give you access to the battery.

Remove the used battery.

Insert the new battery.

Close the latch to secure the battery.

Replace the seal that covers the battery.

Lay the watch cover over the seal. Use a screwdriver to turn the cover to the right until it locks into place.

Test the watch to be sure the battery replacement corrected the problem.


  • Watch batteries are sold at most jewelry counters in department stores and at hardware stores.
