I can't consider a vintage Rolex collection without a Sub, a GMT, an Explorer, a Milgauss, and a Daytona.
Having several of them, I mean several GMTs, Subs Explorers and so on, well, is just unavoidable.
How can we resist to the pleasure of owning several of thems? The variations are often more than just a detail.
For example, you mentionned a lot of 1675s, but what about the first GMT, the 6542? Here again, we have several variations, and some interesting ones!
Same for the Subs, and each of them.
My guess is that we all start in an horizontal way, but that, we time passing, we dig into a vertical way.
So, yes, quite a lot of us are both, horizontal AND vertical collectors.
Best, Bill, and, once again, cogratulations on your huge and remarkable GMT collection. I love a lot the ghost insert you put on your ealry 1675 Cornino CR.
