I lost my silicone strap with black buckle on holiday. Subsequently I contacted Garmin to ask for a replacement (to buy) as the shop does not include the black marq strap with black buckle. Answer of Garmin: not sold separately, we’re sorry! As we say in Dutch: I fell of my chair
A few years ago I had the ceramic Apple Watch 3 which had a silicone strap with a ceramic closing. These straps were only sold by Apple when you had the corresponding watch.
This is normal, silicone straps wear over time and you need to be able to buy a replacement.
so now I am stuck. Thanks a lot Garmin, you rock!
