Model Name: SE (2nd generation) Size: 40mm Purchased in September 2023. I initially used it at work, but I haven't used it for the past few months, so I'm selling it. It has few scratches and is in very good condition. I unpaired it before checking the battery, so I can't confirm the battery level. Comes with a light blue genuine band. It shows signs of use, but it's an accessory, so I won't lower the price for that reason. Charger and packaging included.
