Bulova rebuild


Recommended Posts

My first teardown is this gold Bulova with a 1453.10 movement. I found the service manual online.

 

I did ok except one screw flew out from the tweezers and is gone for good, that is somewhere on the floor. The service manual has an ISO part number of my screw of 10.057.01

 

Any tips on where to find this replacement screw?

Hunting down parts is where half the fun is...

A search on Jules Borel suggests this movement is based on AS530.822

Cousins has a tech sheet for the AS 530 https://www.cousinsuk.com/PDF/categories/3946_AS 530.101smalleer.pdf. It doesn’t cover the 530.822, but in the list of screws for the date mech we see your subject part with an AS number... 52740.

Searching for that part on Cousins gives this https://www.cousinsuk.com/search?SearchTerm=52740

    • That would be something! Which brings me back to;  
    • you think you're going to sleep tonight you're not, you're going to ponder the question of what makes you think those of the right parts?  
    • Does anyone knows what size case a need for a dial diameter 20.60mm?
    • Sounds like the story with my Rolex. Poor (expensive) job done by an official Rolex dealer with an "in-house" watchmaker, hence I learned watchrepair and did the servicing myself. Same story as I learned with the Omega 861, again poor job by an "in-house" watchmaker by an official Omega dealer. Once your watch goes through that back-door, you have no idea what is going to happening to it 🫣   Quite nice that they sent back the parts which had been replaced !
    • yes that's definitely not right at all. I have a picture one of my friends has a Omega coaxial there was having issues to lose asking me where he should send it. As that's a specialty watch I suggested the service center. When he got it back he sent me a picture so the replace the dial as you can see the hands the mainspring barrel and I think the price was really quite decent considering all the stuff they can replace. So I do know they do change the barrels but the other person I worked at the service center when I would ask questions and unfortunately I can't remember all the answers. I think a lot of the changing a parts is at the discretion of the watchmaker. Plus I don't know enough about the chronographs and whether that would be considered a vintage watch? I take some of the vintage watches may have been sent directly to Switzerland or another service center. Obviously with a watch like the one down below they probably have a infinite supply of parts is its relatively modern vintage stuff becomes more interesting even the watch companies don't have necessarily infinite supply of parts. But no matter what the watch shouldn't disintegrated six months that's definitely an issue.
