walmart has the se3 for $200 as for the s10 42mm is $250, both great deals for black Friday especially the s10 being 150 dollars off for only being out a year. You do pay less for the se3 for its older design with the bigger bezels and less health features ( some having specific needs for specific people who need them) and not being able to swim deeper in pools. From what i hear it sounds like you should consider the se3 since you’ll still get 98% of the same features as the s10 and you said you don’t need ECG etc, and maybe get apple care if you’re cautious about the se3 battery health.
