Have had my B1 for a couple of years now. The only gripe I have is that I've put two batteries in it in that time, thought they might last longer than that. It may have been in the shop for a while with the first battery I suppose.
With regard to the geared bezel, a full 360 degree rotation of the bezel turns the outer ring of the flight computer about 440 degrees. Maybe it's just to speed up the process, it just may save you valuable seconds when calculating that fuel burn!
I have also just had my B1 returned after a battery and service. They polished it too, looks like new again. They did try and tell me that it needed a new crystal (flash name for the glass!) as it was scratched but at AUS$265.00 I gave it a miss. I'm buggered if I can find any marks on the crystal!
Just buy one!
Cheers,
Hollywood
