Apple Watch SE 3 [GPS 40mm] Smartwatch with Midnight Aluminum Case with Midnight Sport Band - S/M. Fitness and Sleep Trackers, Heart Rate Monitor, Always-On Display, Water Resistant.
I purchased this 3 months ago to check my sleeping. All's good, no longer need this. It's a great little device, I just don't like wearing watches.
I did buy a new band that is larger and more breathable, so you'll get both bands.
