The MK I is regarded by many as the most attractive version of the C5, and I concur. However, I use this watch too seldom and have a strict "one in, one out"-policy.
The mainspring snapped in 2014 and was replaced. I have no other documentation than the included reparation ticket and email-receipt, as the rest was lost during a relocation.
There are just a few very fine hairlines as is expected of a used watch, and no deep scratches. The sapphire crystal is pristine.
