I have quite a few watch brands from all over the world. For some reason this Timex electric from 1979 is capturing my attention this week. I am not a particularly fond of battery operated watches or Timex, but this one is different for some reason. Post your watch in your collection that seems to draw you in more now than before... -

You can use bombe jewels with regular pivots if you put the convex surface facing the shoulder. You see it on (primarily older) high end pieces, particularly nearer to and including the escapement. -
They are for balance wheels only and wheels with similar pivots (B = bombé). You can use flat jewels for balance wheels (not recommended) but no bombé jewels for ordinary wheels. -

I also just realized I had that tech bulletin saved...but in French for some reason 🙂 No, I don't speak French. 2172_Bulova 11AOAC 11AOACD 11AOACB.pdf While parts are drying I'm on the hunt for a replacement crystal. I can measure the opening and get a generic one, but it'd be nice to find out what the original looked like first. Of course, case code 3093 does not appear in any of my reference materials. JulesBorel lists a C3093 case code, and shows Bulova part # 1222-5. Does anyone have information on this guy? I found a thread here talking about how the -5 is the height of the crystal, but that's as far as I've gotten. I also found one site that claims to have it in stock, but before I risk my $20 I'd like to confirm it's the right part.
