I am selling my Apple Watch because I recently purchased a new one. This is an authentic product purchased in 2019 from Yodobashi Camera. Last month, the ECG function stopped working, and I had it checked at an authorized repair shop. They said it couldn't be repaired, but there were no problems other than the battery's aging. Other functions such as apps and notifications work without any issues. Gold Apple Watch Series 4 body, charging cable included, with box. - Model: Apple Watch Series 4 LTE compatible - Color: Gold - Accessories: Charging cable, body cover, box - Condition: There may be some minor scratches, but it is generally in good condition. - Battery: 74% The charging connector is not included. I will include a white band (SM size), although it is not an official product. Please let me know in the comments if you don't need it, as it shows signs of use. I do not have any pets, and I am a non-smoker. Thank you for reading this long description. Model Name: Series 4 Size: 40mm
