Apple Watch Series 2 is Slightly Thicker and Heavier Due to Larger Battery

While the Apple Watch Series 2 looks virtually indistinguishable from the Apple Watch Series 1 to the naked eye, tech specs confirm that second-generation models are actually slightly thicker and heavier than original models.

38mm models of the Apple Watch Series 2 are 11.4mm thick and weigh 28.2 grams, compared to 10.5mm and 25 grams for original 38mm models.

Similarly, the new 42mm models are 11.4mm thick and weigh 34.2 grams, compared to 10.5mm and 30 grams for original 42mm models.

This means that all Apple Watch Series 2 models are 0.9mm thicker and up to 4.2 grams heavier, likely due to the inclusion of an up to 35% larger battery, but the real-life difference on the wrist should be relatively unnoticeable. The width and height of the Series 2 models remain unchanged.

Apple did not confirm that Apple Watch Series 2 models have a larger battery, but it is likely considering that battery life is equal to original models despite the Series 2's inclusion of a faster S2 chip and GPS. A future teardown of the device should confirm the larger battery capacity.

I just want a watch that looks like a watch, not a mini iPhone. Samsung can do it, why can't Apple?

Yes, a phone that is .9mm thicker and has 20% more battery would be great. The watch? It's pretty chunky already.
