The D-1 Diver has a curved case shape that tucks beneath the edge of the bezel for optimal grip and a wrist presence that nicely balances the 42mm case width and the 44mm bezel width. Thickness is 16mm
link and the lug to lug is 49.8mm, so don't expect the D-1 to wear like a vintage skin diver. That
link being said, almost like a Seiko SPR777, I found the
link D-1 to be perfectly comfortable on my 7-inch wrist.
