Ok, this may be a bit of a strange one, but I've recently had my Fenix 5 replaced due to issues with it, and the new one is working perfectly. However I have what might seem a strange question regarding the loop fasteners on the strap.
Now there are 2 on the Fenix 5, and I'm sure that on my previous one both loops had teeth on to lock them into the holes on the strap, but the replacement only has a tooth on one of the loops. I could be completely mistaken, and it was the same on my previous watch. Could someone take a look at the loops on their Fenix 5 and let me know whether they both have teeth on?
