Hi, anyone have a source to match a Bulova crystal with a specific case number?  Looking for the Bulova-specific crystal part number (or GS if they made it).

Specifically a Bulova case Q526 (PO date code, 1980)

Thanks

Welcome to the forum.

Looks like a standard flat crystal so you just need to measure it.

Edit

Had a quick search and it's not clear which yours will be so can you post photos.

Also have you any experience of working on watches?

Thanks Andy.

Yes, been restoring vintage watches for 15+ years.  I know how to measure/order a new crystal, and will do that as last resort.  But I know that there are still original Bulova crystals out there.  I just need to know the Bulova part number for it, based on my case number.  It's the reference material and documents that are scarce, finding the number is the hardest part in my experience.

Best,

I believe Bulova's last case part catalog was the 1979 supplement. There may be a more recent one (seems like there should be) but I haven't seen it. Unfortunately, the highest 'Q' series case in that catalog is Q519. Some of the 'Q' series watches did take a crystal with the same numbers as the case, but not all of them.

      Regulating is too touchy

      By BobG · Posted

      I’m fairly new to this and have worked on maybe 30 or so vintage and new movements. I recently went through a NH35 movement that I picked up with low amplitude. 140-150 degrees and impossible to regulate. I did find that the train bridge was not flat and when the screw nearest the barrel was tightened the wheels no longer spun freely so I replaced that with a spare and all good.  I cleaned it and lubricated it, including the balance cap jewels and it came right up at 220. I could get the beat error down below 0.5 but I’m chasing the rate all over. It will be down -15 and I’ll just touch the regulator arm and it will be up +15. This is a practice movement for me as I want to learn and improve making positional error corrections on the Etachron system.  The amplitude has fallen off a bit as well, 200. I’ll let it run overnight but is there anything I’m missing that can cause the rate to change so significantly with a very very small movement of the regulator? Could the hairspring be damaged and very particular to both the  regulator and stud position?  Could the regulator pin positions off? Either too open or closed?

      Longines with 25.17 caliber

      By BlueHarp · Posted

      The thing is you have to provide Longines with a serial number AND a reference number when you fill the form. I have the first one on the movement, but I can't see the other one, which sould look like L.xxxxxxxxxx. I mentionned the number inside the case and I sent the mail. Wait and see... Here are some picture I took yesterday when I received the watch.

      I was in Leeds not too long ago. I went to my first (and only) Premier League game, Leeds and Aston Villa. 0-0 tie.  (Obviously this was prior to relegation.) Loved the city, actually.
