A couple of years ago I picked up a 7750 LeJour Chrono which was in poor cosmetic shape, with most of the black ?PVD? finish worn off. I contacted someone who offered to blast the case and, as agreed, I removed the movement and sent it off. That was the last I saw of it.
Recently I got a new, similar style case from an eBay seller, to suit a 7750. The dial size is correct so all should be fairly straightforward. However, at the very least, it will involve fitting the new crown to the stem and I'm nervous about screwing it up. Can anyone recommend someone who would do this for me?
