Had to replace cap jewel for 3 wheel. Very tiny jewel, was able to reuse original retainer.
So a couple questions. On subject watch, what is the inside case back signature? I see Geoff's yellow example has "Bulova Quality" on inside, but no indication of subject case signature. So I believe the way listed, this is a possible Trident w/ engraved bezel. No ad for this, but no conflicting ad indicating it could be something else that I can find either. So I'm somewhere between two ticks for tentative and one tick for unconfirmed. I remember that one tick doesn't mean it's absolutely not a Trident, it just means we are guessing at trident based on all this. One tick isn't a bad thing, but can be an informative thing.
Edit: Case serial numer suggests 1934 date,
