These beautiful Timing Bezel Inserts were custom manufactured in our shop as a more robust replacement for Stocker and Yale SANDY 660 Navigators watches and as part of a "proof of concept" project. They are machined out of solid 316L stainless steel. We have been told that they also fit many Seikos, but if your watch isn't a SANDY 660, you should measure to ensure a proper fit. These have never been available before. These bezel inserts come in raw stainless as shown above. You can add paint or jewels as you desire.
