I've owned this piece for about six months now and whatever else I've been wearing I just keep coming back to it.
It is just that little bit larger than the non-chrono C5 and it seems to be better proportioned for it. It has a really classy look that works well both formal and casual. The subdials are subtle but easy to read and the spinning tenth seconds when the chronograph is started is an exciting feature.
The watch is easy to read and the luminescence is easily sufficient for darker viewing.
The build quality is beyond reproach, from the beautifully shaped, comfortable case through to the perfectly sculpted and applied numerals on the dial. It has a screw-down crown for improved water resistance, a sapphire crystal and everything, lugs to pushers, is in perfect proportion.
Highly recommended.
