This is a 40mm Series 1. It's a used item, but the exterior is in beautiful condition. ⚠️ Because the screen has been replaced, Apple Pay is not available. (Therefore, important functions like transportation touch payments are also unavailable.) The screen had display issues and the side button was faulty, so the screen was replaced and the housing was swapped with another unit. Also, the battery was replaced with a new one at that time. The screen has minor scratches, but there are no scratches that catch your fingernail. I think it's at a level that wouldn't be noticeable if you put a screen protector on it. *I've tried to show it clearly in photos 11-17.* The housing has been replaced with a clean one. Therefore, the serial number is different from the actual one. The actual serial number is: GQ2JD0E8Q07T The battery health is 100%. *This is the current state, so it may be 99-98% when it arrives. Please be aware of this.* All functions are normal except for the unavailability of Apple Pay. Included items: ・Main unit ・Charger *The charger is a third-party product and its operation has not been confirmed. Please consider it as an extra.* Activation lock has been removed, and it will be shipped via Nekopos (a Japanese delivery service). My personal opinion is that although the Apple Watch SE has already reached the end of its OS support, it still has the minimum necessary functions for daily life. I usually use the latest model, but I didn't feel particularly inconvenienced when using the SE. Please consider it.
