It's huge, but the truth is all watches with these capabilities, like certain Garmin's, are just as big if not bigger.
My diving days are behind me, and I need my watch to fit under my sport bike racing suits, so this one is a psss for me, but I can see a lot of people loving the thing. Until that top edge gets incredibly dinged up, that is. Titanium is too soft and that edge is too square for good results in the long term. They should have put in a sacrificial bezel at the very least.
Pricing was a pleasant surprise after the wrong (as usual) 1K+ rumors.
ETA: Oh hell, who am I kidding. Mine will arrive with green Alpine Loop band on September 23. I would have ordered Orange, but I know what that would look like after two months.
The fact that this works with existing 44-45mm bands put it over the top for me. Good move on the part of Apple.
