This is a WONDERFUL watch, and I am really bummed that I have to return it.  But it is just too BIG.
The Amazon specs on it are somewhat erroneous, especially the thickness, which is really 14mm, not 10mm as printed.
FYI the actual case diameter of the round part is 49mm.  At the crown horizontally it is 53mm.  At the wrist vertically it is 57mm, which is just too big for my wrist of less than 60mm across.
Also, the Amazon specs state that the band material is "Sterling Silver", which we wouldn't want for such a watchband anyway.  Of course, the band is stainless steel.
And it is HEAVY--7.5 ounces!  Could probably count as part of your weight belt if you SCUBA!
I hope they make it in about a 42mm size soon, and 10mm thick--I will buy!
