Whether changing batteries or carrying out minor repairs, it is sometimes necessary to open a watch yourself. Great care is required, as fine movements are sensitive to improper handling. However, with the right tools and a little patience, many jobs can easily be done yourself.
1. open the screw-in cover correctly
If your watch has a screw-in lid, you will need a special case opener or alternatively a rubber ball. Place the tool on the cover and carefully unscrew it anti-clockwise. A secure grip is crucial to avoid slipping and scratches.
2. carefully lift the pressure lid
Pressure lids can be recognised by a small notch. Carefully insert a watchmaker's knife or a similar flat tool here and slowly lever the cover open. Apply only light pressure to prevent damage to the case.
3. opening screw-down cases
Some watches have screw-fastened backs that are secured with small screws. In this case, you should only use precision screwdrivers to loosen the screws precisely and without slipping.
Important note:
Opening water-resistant watches in particular can damage or loosen the seals. This will cause the watch to lose its water resistance. If you are unsure or do not have the right tools, it is advisable to consult a professional watchmaker.
