Had a try-on appointment this morning. My gal let me try on as many different ones as I wanted.
The only one that was hard to judge was the link bracket since it had all the links in and was huge on my wrist.
The leather loop was the large size, so I could clearly tell I would need the medium for my 185mm wrist. The nice thing is that each segment is magnetized, so the band felt secure.
The 42mm classic buckle fit well, which is good since that's the one I bought. The band is wider in real life than I was anticipating, but not outrageously so.
The Milanese loop band is a very soft, flexible material and looks great. The loop isn't too thick where it folds over along the bottom watch lug. It does, however, feel like the magnet could slip or become dislodged by putting my hand in my pants pocket if I catch the edge just so. So I'm kind of glad I opted for the classic buckle instead, as the loop was my second choice.
The link bracket is beautiful, but I wasn't ready to spend that much. Maybe later as an upgrade I'll buy the band. It was quite heavy (in a good way). Heavier than my Concord Mariner SG's stainless steel bracelet.
The fluoroelastomer band is much softer and more flexible than expected. For a 'rubber' band, it was about as nice as it can get.
The watch screen has what looks like a super slim air gap. Not sure if it's real or just apparent. The watch seemed fluid enough, just like in the demo videos. The haptic tap was not super strong, but it looks like there's a setting for tap strength if need be.
