I was not happy with the watch holder I had, it was always difficult to fit and the gear and brake cables were in the way. So I made my one version. It is strapped on with a simple o-ring, like the ones you get with a Garmin or Wahoo bike computer. It works with Suunto, Vertial and Ambit and most likely any watch with 22mm wide straps.
