The main unit was replaced with a new one after repair in December 2023, so it has been used for about two years. The gray strap is genuine, and the white one is not. The screen has no noticeable scratches. Please take a good look at the photos as this is a used item. It held a charge long enough for a full marathon and a 100km ultramarathon. Only the main unit and straps are included; the charger is not.
