As of the latest announcement in 2016, there appears to be 3 types of Apple watches
- Original (Series 0?)
- Series 1
- Series 2
What isn't clear is the distinction between the original Apple watch and Series 1.
Prior to the announcement, the original Apple Watch (Series 0) listed at $349. Then it was discounted to $249.
Part numbers of Series 0: - MJ3T2LL/A MJ2X2LL/A (Black) - MJ3R2LL/A MJ2W2LL/A (red) - MJ3P2LL/A MJ2P2LL/A (green) - MJ3T2LL/A MJ2T2LL/A (silver) - MLC42LL/A MLCF2LL/A (Orange) - MLC52LL/A MLCG2LL/A (Silver) - MLCH2LL/A (Rose Gold) - MLC62LL/A MLCJ2LL/A - MLC72LL/A (Gold + midnight blue)
From what I can tell, the original Apple Watch has these differences from Apple Watch "Series 1"
Series "0" Series 1 Cost $249 $269 CPU 1 core? 2 core both are Splash resistant both have Wifi b/g/n both have bluetooth 4.0 both have a heart rate sensor ??? accelerometer ??? gyroscope ??? ambient light sensor
