Apple has been advertising their Watch cases as being only 10.5mm thick.

Some people have used this value to diss other smartwatches such as the Moto 360, spec'd at 11.5mm (which includes its sensor pod and display).
A while back, I posted this question about the watch's actual dimensions:
Due to Apple posting their specs for wrist band makers, we finally have the schematics, which tell the true story. The Apple Watch is actually 12.46mm thick in total. Making it almost 1mm thicker than the Moto 360, not 1mm thinner as many had supposed.

Apparently Apple is only counting the metal case. But leaving out the sensor pod and display bulges (marked in red above) is a bit disingenuous, especially since the other two dimensions follow normal watch rules.
The thickness of a watch is normally defined as "the width between the case back and the top of the crystal." In other words, the entire watch, not just the middle section as Apple used.

Apple says it's 10.5mm thick, but isn't the sensor pod another 2mm ?
I've taken a couple of side views, and resized them to be 42mm high, and it's always like 12.5mm thick if you include the sensors.
Can anyone else with more imaging skill check? Thanks!
