I buy in to patina, for some models.
My Navitimer "Twinjet" has not been cosseted. The pvd is quite worn in places, and there is a plethora of scratches to the case, lugs, crystal etc. But it is part of the piece's charms to me. Also I have no qualms over wearing it for everyday tasks
An aded bonus is that it is a big 'un (though I don't totally subscribe to the theory that it was aimed at airline pilots with poor eyesight!) so I have no difficulty in reading t, which was not the case with my previous "norman size" Twinjet.
