1950 Heuer triple date bumper watch project

#1 Post by Squash61 » Wed Jun 01, 2016 5:26 pm

I bought this one several months ago. It did not run and I could not get the back off and whoever tried before me, chewed it up quite a bit. I sent it to two watchmakers and neither could get the back off even after using penetrating oil.

I got it back and was willing to try the "glue the nut to the back" trick. I decided to go with washers instead to give me more surface area to glue.
I used super glue and let it set overnight just to be sure.
I set the watch in my wooden case vise and then then to the bench vise. I gripped the washers with a pair of slip joint pliers and twisted pretty hard. At first the wooden vise gave way, so I had to chisel out a deeper grove so it would sit tight in the vise.
I twisted real hard again and low and behold, the case back started unscrewing.

The bumper movement has a little rust on it, but the balance seemed good. I'm sending it back to one of the watchmakers who will try and service it. Fingers crossed that he doesn't
need parts because that will be tough. (Unless someone here knows of a source?)

It's a rare watch that I would like to see running. It's stainless with a solid yellow gold overlay on the bezel and tops of the lugs, but not all watches can be saved.

Anyway, more to come. Oh yea, I got the washers off by soaking the case back and washers in acetone overnight.

So....

How do you get the washers off? I ask because I have a far less valuable Stormking V the back won't come off of?

Hey Pat, you soak the case back and washers in acetone. (Nail polish remover if you don't have acetone) I let it soak over night. Worked like a charm. The key is to make sure as much of the watch is supported on the strongest part of the watch when you crank down on the wrench. You don't to snap a lug, so for delicate lugs, this may not be the best method.

Wow! Is that the factory "glow in the DAY" option. 8-)

Patrick, if you speak softly to it whenever you are around and tell it you will be gentile, it will eventually realize all humans are not cruel and demented and open up so you can begin to heal its grievous mental and physical wounds. Joel

Pat, tried super gluing the biggest nut that will fit onto the case back? cut some ridges in the nut for extra bonding.

When it's off, soak in acetone to remove the nut.

ive had to do it on one so far with good results.

Almost any nut will work. I use these as they obviously have more surface area and the glue sticks to the nut side every time.

Back from my watchmaker and it came out great. Everything functions. Very happy.
