Amazon.com: SAMSUNG GEAR S3 FRONTIER Smartwatch 46MM …

As for the durability of the watch, the back of the watch has glass. My glass is broken, it is not currently hindering the function of the watch, but eventually, I am going to want it fixed. I don’t know if the watch was broken before I received it as it had a sticker on the back that I needed to remove if I wanted the heartbeat monitor to work.
