A great modern interpretation of the Challenge diver. Dimensions are great. I love it, every time I look at it I think I'm Bond in Dr No. Its all going on up top to hold its own at Monte Carlo Casino with its glossy light play and discreetly toothed bezel and small crown but purposeful underneath to just get the job done. To me (and I think the Citizen designers when drawing this up) should be the new Bond watch. Flemings' not Pinewoods Bond, the peoples Bond not the corporate Bond in his OTT Omegas. Even the name Citizen Fugitsubo Challenge Diver is perfect for Flemings' Bond. A middle of the road civil servant but oddly exotic and risky. We've had Bond Seiko's now it should be Citizens turn. The bezel turns just great to me and the crown size appropriate for this model but the crown does feel a little fragile, maybe because its titanium? Also the screw in is so shallow I find I keep checking its all the way in, its like two turns and your done.
