TWO Smart Watches and Charger

I have two Smart Watches (both Uwatch2S) that I keep taking off and ‘losing’ so have no use for them. Both for $50 OBO. Comes with one charger that works on both watches (a second charger would be $8 on Amazon). Both have sports tracking, heart rate and O2 monitoring, as well as message previews, weather info, a stopwatch, sleep tracking, music control and find my phone. Compatible with the “Da Fit” app for iPhone and android. Hoping to sell as a pair but open to offers.
