How does the size of the new compare to the old. -

As I wait for my first set of watchmaker screwdrivers to arrive, which is taking longer than I had hoped, I'll post a photo of the small stockpile I made to work on. I'll be starting with the Citizen: the missing crown is my doing. I unintentionally applied pressure from the side and off it came. I've put it aside, and I'm hoping it's detached rather than snapped, and without damage to other parts, but until I have the screwdrivers I can't remove anything to examine the stem section. Two of the Seikos are are working, quite well actually, although for the price I paid, none of them should really be in "serviced" condition, so after letting them run on one wind, I've left them unwound. The Citizen was the cheapest, and so the one I could most bear to go wrong with, although all of them are rather nice watches. I think they're all from the late 50s to very early 60s, but I haven't managed to date them more closely than that. The Citizen and the Seiko Crown each have a small crack in the crystal, so I'll be hoping to replace those. -

In watchmaking, there is supposed to be a tool for everything.. 😉 I believe there are dies that "flex" square crystals to reduce the outside dimensions. Robur-style, but square instead of round. But, like @Neverenoughwatches already suggested, you could also make the crystal a bit smaller.

Setting don't look to be moveable, unless you eliminate the u-clip. Bad idea. I would check pivot ends with good magnification to make sure it needs smooth/ work. You should find whats wrong, before attempting to repair it. Seems to me shimming is best as its reversible & accurately adjustable.
