I picked a cheap speedmaster reduced bezel to try to make work. Inner and outer diameter of the bezels are quite similar, just the diameter of the press fit is a little smaller on the bezel so I am trying to get some time on a lathe to turn that dimension out to fit the compax.
I am aware that I have a lot of parts to source to make this close to presentable, but for the time being it is as close as I can get to a Nina and it’s pretty fun trying to make it work. I have a chrono sweep hand and maybe a bezel soon. Not trying to fool anyone about it either, just really like these early Ninas and wanted one to wear.
Here is a picture of the bezel sitting on top, not yet pressed on. I’ll update on the fit when I do it.
