40MM I haven't used the watch much, I bought it less than a month ago and I don't wear it much. It has no scratches, and its box and charger are available. I bought it from Extra and also got 3 screen protectors for it. Whenever a protector is removed, you can go to Extra and they will install a new one for free. I also got a service for three replacements for two years in case of misuse. Urgent sale today. Case Size: 40mm Color: Black Series: Apple Watch SE 3 Connectivity: GPS Condition: Used
