Hi

Need your suggestion please, this case gasket might be 60 years, and has become, if effect, part of it. It is even difficult to remove by scratching with tweezers. Any suggestions please?

Also, on the same watch (vintage oris), is there any specific trick to remove such a bezel?

 

Thank you!

Heat up any sharp point metal resembling screwdriver., it comes out in pieces ,clean physically to remove the rsidue and soak in solvent to chemically dissolve, remove and brush  clean the groove, No chemical or heat on the bezel.

Something mild, that wont stain. Isopropanol, methylated spirits, lighter fluid, or at a pinch acetone, but keep it away from any plastics, and that probably includes the finish on the bezel.

It's probably a paperclip-ring bezel so first thing you should check is if you have a 1 part or 2 parts assembly.
By 2 parts I mean Bezel + Insert ... but should be a 1 part.

If it's a 1 part you just have to push a 1 razor blade under it, taking care not to scratch the case, then push a 2nd one opposite to the 1st one.
Then you should be able to put a thin screwdriver under the bezel and make lever ... the bezel should pop off.

If it's a 2 parts just remove the insert, taking care not to bend it, then you will see the paperclip-ring that maintain the bezel on the case.
Just grip the spring with tweezers and pull it off.

Sorry for late response, submerge in deisel fuel let soak overnight.

Following bezel removal, moderate flame by a cigartte lighter or torch, right aiming at the gasket to ruin its structure so the gasket can  be scraped off. 

If memory serves me right the case material is base metal, so don,t forget and leave it soaking for weeks.

Regards

      Hello everyone from Idaho. I started up the hobby about two years ago and love it. My latest repair, that I'm very proud of, is an Oris big crown pointer date 7400B. I'm excited to learn and to help out where I can.

      Bezel for 1954 Rolex 6581 Oyster Perpetual

      An update... I bought some 316 steel washers from McMaster Carr. For days I have been turning it to get to what you see in the image.  it is not done, of course.  the inside diameter of the top as shown is close. The washer is too thick, so I am gonna need to figure a way to make it thinner. Last week I had a long talk on the phone with @SwissSeiko and got some tips. He suggested Harbor Freight insertable carbide cutters. Wow, they work well. Miles to go before I sleep. Here is my setup

      Plastic gasket for Citizen case back.

      By Kab · Posted

      Hello all.  I've been working on a Citizen H145-S073545 radio controlled. There was a plastic gasket in between the case and case back. Putting it back together I used a press, witch I think was a mistake, because it cut the gasket open. I've been looking online for a replacement but not having much luck. I've tried a couple crysta gaskets but that didn't work.  Any ideas of where to find these gaskets? Thanks all.

      Loose pinion

      By mbwatch · Posted

      Yes I think blue thread locker would help you out here. You will lose the safety mechanism if the mainspring snaps, which risks damage to train wheel teeth. But your watch might run. You can maybe try inserting a hair inside the pinion and threading it on. That might give it just enough to grab hold without thread locker. Or a tiny piece of superfine copper wire, a strand from some stranded electronics wire.
