It depends on the type of repair. Some simple fixes can be done at home, but more complex repairs are best left to professionals.

1. Simple Repairs

You can usually handle strap changes, bracelet adjustments, or battery replacements (for quartz models) with basic tools.

2. Complex Repairs

Tasks like movement servicing, crystal replacement, or water-resistance sealing require professional skills and equipment. Attempting these yourself could damage the watch.

Summary:

You can do basic repairs like strap changes or battery replacements at home, but for movement or water-resistance issues, it’s best to use a professional watchmaker.
