@icedquinn had a Garmin Swim 2 until the... screw.. structure??
The part of the frame of the watch that holds the brass beads that the screws for the wristband attaches to
That gave out
Had a battery life of about 5-7 days in watch mode, really good HR sensor
Kinda pisses me off that it broke, it was a really nice secondhand watch that lasted a while already
