Picked this up today from Mark (mcat) on the forum and delighted with it. Unusual piece with no serial number and #0 in the guarantee booklet. Mint condition case, same for the strap as well. Always liked the C7 but was wary of the wear I had seen on various bezels with chipping to the colour in the case of some brown, black and BRG bezels - an affliction shared by the C70 range.
This seems to be a better solution - whilst there are markings for the Tachy on the bezel, it is basically S/S. Also looks rather classy, understated gentlemanly - much like Mr Damon Hill... :
