What is Watch Modding?
Watch modding (short for modification) involves customizing a watch by replacing parts such as:
✅ Dials – Swap out the standard dial for a custom design
✅ Bezels – Change the look with a ceramic, metal, or aluminum bezel insert
✅ Hands – Upgrade to different styles like Mercedes, cathedral, or sword hands
✅ Crystals – Improve scratch resistance by upgrading to sapphire crystal
✅ Straps & Bracelets – Change the style with leather, NATO, or stainless steel bands
✅ Movements – Upgrade the watch's movement for better performance
Watch modding is popular among Seiko owners, but many other brands can also be modified.
