Let this be one more post about the merits of the IWC Pilot Chrono and one more proud IWC owner who battled back and forth between the 3717 and the 3777. For me, though I may be in the minority of Pilot Chrono aficionados, the 3777 won the battle.
I love the dial (and pretty much everything else) of the 3717, but the size and particularly the more vertical bezel shape of the 3777 just seemed to fit my wrist and my style a bit more. I still question my decision sometimes, particularly when I see a photo of a 3717 off of my own wrist, but I'm more than happy with my choice.
Also, I can not recommend the product and ESPECIALLY the personalized customer service of Bob Davis over at --------------. I was looking for a deployant clasp for the stock IWC leather strap and several forum members recommended his products. Not only is the clasp excellent, but Bob called me about a half hour after I placed the order to be sure I was getting exactly what I needed.
Great service, great products, and I love my 3777! Forgive the dark pics, I'll take some proper ones later on.
