Are these straps compatible with other Garmin watches?

Yes they are - but not all of them. The Garmin Instinct 3 45mm uses 22mm QuickFit straps, meaning they are only compatible with other Garmin watches that support the same strap width and QuickFit attachment system. This makes them suitable for models like the Garmin Instinct 3 Solar 45mm, as well as select versions of the Forerunner and smaller Fenix models that also use 22mm bands. However, they are not compatible with the larger Garmin Instinct 3 50mm or watches like the Fenix 7X, Tactix, Quatix, or Enduro series that use wider 26mm straps. Be sure to confirm your watch size before purchasing replacement straps.
