How to change the battery on the Ronstan ‘Clearstart’ 50mm watch

Please note this is done at the users own risk, if you are not comfortable changing the battery, please take the watch to a qualified watch maker.

Tools required:
•    1.5mm cross headed screwdriver
•    Small tweezers

3.    Note that a very thin rubber gasket will be attached to the back plate in a small grove when the back plate is removed.  Keep this rubber gasket in place.
4.    A white sticker will cover the battery top cover. Do not remove this, but remove the small crossed headed screw as shown by the arrow / text on the sticker and remove from the hole the screw with the use of the tweezers. Note: this screw is smaller than the cover screws.
