The depth is the same on both sizes. And I don't really care about the feminine thing. I just want it to be comfortable. And frankly, that Moto 360 was pretty comfortable.
And lastly, this is why I'm having this internal struggle. Because I honestly don't know what to get, because I haven't worn a watch in 15+ years probably. And trying it on in store for 5 minutes isn't even really going to be a good barometer, cause like I said, I put that Moto 360 on for 5 minutes, and I was completely cool with the 46mm size of that one.
Edit: To be quite honest, I'm probably going to wind up with the smaller one, even though I would like to get the bigger one. Reason being, and maybe I'm being naive, I bet Apple is going to talk me into getting the proper size, which is probably going to be 38mm. There are a number of reasons I feel this way. Crude measurement of my wrist indicates it's around 157mm. If we are looking at the 42mm milanese loop, I only have 7mm down before I am at the start of the loop, whereas, the 38mm, it starts at 130mm. So the clasp will be at the bottom of the watch instead of the top of the watch.
Also, like I said, to me, the most important thing is comfort. And I have a feeling the smaller one is going to be more comfortable.
I really wish I knew the size Tim Cook uses, because I kind of think he has the 38mm.
