100% authentic. Size 38mm. NO flaws. No cracks. No signs of wear. 100% works and still holds a full charge. Has been completely wiped of my personal information and factory reset as of 01/02/2024. Comes with charger, and pink watch band ( size small and they are NOT original apple bands ). I do not have the original black bands and I will not be sending the original Apple box as pictured as well. So sorry! Please note in order to active the cellar line ( non wifi) you must call your phone provider ( AT&T , Verizon, etc) to add a line ro your current plan in order to sync all incoming/out going calls and sms text messages from your iphone to the watch. Your Iphone can be synced with the watch through wifi, However, you will only receive iMessages to the phone and all related wifi activities.
