My wrist is about 175mm, 60mm wrist width. I tried both size on and tried on all the different bands as well. Before I came in, I believe the 38mm was the most proportionate watch to get. After trying on a few different watches and sizes, I asked the person who helped me try it on which was the best size to get, and he said the 38mm. I didn't suggest to him which one I preferred, so I didn't want to show any bias when asking another person. In the end, I'm sticking with the 38mm SS with black sports band and I'll be canceling my 42mm SS black sports band. The best bands I like are the rubber bands. It felt the softest and the most comfortable. The other band that was a sweet surprise was the modern buckle. I fit in it, and it's the second most comfortable band for me, second to the rubber bands. The classic buckle has a leather that's twice as thick but not as supple as the modern buckle leather. The thinner leather of the modern buckle felt much better and wraps around my wrist easily. The Milanese loop was also surprisingly comfortable. I'm still on the fence whether I want one or not. It was complicated to put on, even with the person who helped me try it on. It just doesn't hold its shape and flops everywhere when I am trying to put it on. Once it's on, everything was better and can be easily adjusted. The least comfortable band is also the most expensive, which is the SS link band. Naturally, it's rigid when it comes to flexibility. When I tried the 42mm SS link band, I had 2 links removed from both sides, and there were still room. Perhaps removing at least 1 more link from both sides to get the appropriate fit. I'm wary of the $449 price tag, that comes almost to the $500 price tag of the SS watch case itself. So I'm keeping my 38mm SS black sports band. I also preordered a white and blue sports band. I hope they come before my Disney World trip in May. For the modern buckle, it's currently unavailable, so I'll have to keep an eye on that. I guess my personal tastes are soft and supple bands. In my opinion, when it comes to bands, the $249 price tag of the modern buckle might not be worth it, but it's the second one I like best and so I'll get it. I hope the 2nd and 3rd gen watch will be compatible with the bands of the first gen to make this worth it. For the $449+ price tag of the SS link, it's not worth it. I think you're paying for the "engineering". Think of the first generation Macbook Air priced at nearly $3000, Apple had to re-engineer the whole laptop to get it that small. These were taken with the help of the person who help me tried them on. They were taken about 10-12 inches from the watch, except for the first two pictures. 38mm silver sport + white band: I don't remember if this is 38mm or 42mm: 42mm SS link (I didn't close the clasp. The watch case is way too big here): 38mm SS + black modern buckle: 38mm SS + Milanese loop: 42mm SS + leather loop: (I think it's too big. What do you think?) 38mm SS black + black link: I'd say this look sharp, but there isn't much else when it comes to band flexibility. Colors!
