I'm for wearing the watches I have too, but there are occasions when I'm more selective about wearing specific watches - the 1158, for instance, only comes out when I know it will be protected by a long sleeve in a shirt with buttons, rather than one that needs cufflinks.

I remember one incident when I was wearing a black PVD 510.511 Carrera, like Jeff in a quiet, climate-controlled office. But you have to take lunch, and walking back to the office afterwards, my wrist was clouted by a bike in the cycle lane next to me. Because of my reaction, jumping and immediately intently checking out my wrist, my colleagues were concerned that I had been hurt but I was in fact checking out the watch for scratches! It got off fairly lightly in fact, but I was worried at the time. The moral of the story is, when wearing a PVD-coated watch in a city with cycle lanes on the pavements, let your colleagues be the ones to stand nearest the danger :)

So wear them, you have three great watches. But as Darren said, David's suggestion to Jasper was a good one - get a spare case PVDed and keep the original safe somewhere and you will worry less - I believe Nic even offers a PVD coating service.
