Ronda 715 movement - day and date don't change

New movement, just swapped the day/date wheels over from another 715.  Now the watch ticks and setting the day/date using the stem at the first click works fine.  At the second click, moving the time past midnight usually doesn't update the day/date, or it will update once but not again without manually changing the day/date again first.  A click can be heard and the wheels wiggle but don't change.  The day/date also doesn't update if I just let the watch run for a day.

 

What'd I mess up?  What should I check?

 

Thanks!

The problem seems to be the day wheel.  If I remove the wheel everything works fine, if I put it back on it fails randomly.  I tried a different wheel thinking maybe it was bent or something but no luck.

 

Since it only happens with the wheel on I can't see what's happening.

    • 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.
    • Not SS but very slight wear on the underside edges have a little brass showing under magnification. New crystal arrived £3 with tax. Nice champagne dial color.
    • 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.  
    • Thanks for the replies. I did the job today and found that the oversized stem fitted just perfectly into the worn mainplate without any adjustment. Original stem diameter was 1.24mm and the oversized was 1.40mm. I did have to make an adjustment to the setting lever though. The small pip that engages with the groove in the stem hub was slightly to wide. I made that a bit smaller with a fine file. Don't ask me why that was too big, it just was. All working very well now. No wobble and not pulling out. New crown fitted as good measure.
