At 43mm wide and not too thick at 13mm wide, the watch isn't small, but is certainly smaller than the biggy divers that we are all familiar with as of late. For me, the watch is a perfect mix of being large enough, but not being at all unwieldy. The steel case here is PVD black coated. You can tell that most of the case was brushed underneath the coating. There are more-or-less no sharp edges on the case at all. Running your finger over it is actually pleasing. Because the smooth texture of the coating combined with the many surfaces of the watch allow you to know exactly what you are touching without even looking. Which brings me to the rotating diver's bezel. At first I though it looked too rounded. Not sharp and precision cut like many of the much more expensive dive watches out there. The second you touch and use the bezel, you understand the concept. The bezel is not only easy to grip and read (even though it all black), but it does not cut into your fingers. Jaeger-LeCoultre Master Compressor Dive watches for example have beautiful looking bezels, but some of them are so sharply milled that you could actually cut yourself on them if you were too aggressive or scratched up against them harshly. The C600 though has a very pleasing to touch and use rotating bezel. It might look a bit funny, but it works real well.
Also worth mentioning is the new clasp and deployment system that is beautiful. Ball spent a lot of time on this element of the watch as well, and you certainly won't be disappointed by it. The rotating bezel on the watch has navigational markings. Used by some people I suppose. I would have preferred a standard dive style bezel though. The compass indicators on the bezel are however applied with lots of blue luminant. Actually, Ball seems to want this watch to be a navigational instrument. There is a lot of emphasis on the compass theme. The dial has a traditional compass looking design on it, and both the flange ring and the bezel have compass degree indicators. Compass lovers rejoice.
