This was my dad's watch and I inherited it after he passed. I would like to find the correct case for it. I'm pretty sure it's a mismatch as it fits VERY loose and moves around in the case.
I also could not find a match to this in our ads, and will go with Unknown at this time.
Often these movements required a ring that fits in the opening of the caseback; perhaps the ring is missing, causing the looseness. I think the lines and markings of the dial look to match the bezel opening; the case and dial may be correct.
In reply to I thought maybe the case by Reverend Rob
When I focus on the case right next to the crown, it appears that the bezel is slightly wider there on the Lexington. That is, the Lexington dial is slightly more barrel-shaped? Also, is it the band covering them, or are the lugs on the Lexington shorter?
Despite the magnification on the Lexington image being slightly higher, if you put a ruler on the case edge next to the crown, it is indeed smaller than the SW.
Edit:
Scratch that, it appears to be some kind of crystal distortion. I'm good with Lexington.
