Apple Watch Series 4, bought at the beginning of 2019. Still works well, but battery only lasts through one day with minimal use. If you’re using the HR or EKG apps frequently it goes faster. Wear and use pictured. Needs to be cleaned, but I don’t have the tools for that right now. Space grey, smaller 40mm size. Band is not from Apple but is a similar style as their magnetic Milanese loop band. If I can find the charger, I’ll include it. Will come partially charged and factory reset.
