Apple Watch Series 7 45mm

One year old, in excellent condition. Has the new expansive edge-to-edge screen. Supports blood oxygen measurement, ECG, sleep tracking and fast charging. In fact, the only features the newest model has which this lacks are car-crash detection and menstrual cycle tracking. Aside from these, it's still the most advanced 45mm watch Apple makes.
Battery still achieves 91% of maximum capacity -- easily lasts an entire day with multiple workouts and an entire night of sleep tracking (plus, it can fast-charge in 20 minutes, while you shower).

Includes premium "Sequoia Green" leather link band ($99 value), and original fast-charge capable charging brick and cable.
Buying this model and band refurbished from Apple would cost $430-500, versus my asking price of $299.
