I've been searching up and down on the web for the different part numbers for the Apple Watch Series 2. More specifically, I'm looking for part numbers for the 42mm Apple Watch Nike+ and the 42mm Apple Watch in Black Stainless. Ex: M******/A. I'm able to find model numbers on Apples website that has the A1234 for example, but can't find the other numbers. Would someone who owns one of these devices please post? Cheers!
