There’s fun and quite a challenge in modding.
You may not know it, but you’ve already modded a watch by merely changing its strap. At its core, watch modding is all about swapping existing parts for newer ones. It’s fun and exciting, as it allows you to personalize your watch, but it can be challenging once you go beyond replacing the straps and start modding the hands, movements, and other parts. That’s where we step in. Certiga Works is here to take the
hassle out of modding.
