Just finished up my first repair attempt on an 1939 Omega 38.5LT1 GSTP watch.

Bought it as a non working watch for $80 Usd and was pretty happy I just had to replace the mainspring with one from a parts watch (Still took 3 hours though)

The barrel had some very rusty looking oil on the arbor, so I cleaned it and the mainplate/bridge pivots with Naptha.

Took me a about 2 hours just to rewind the donor mainspring. my conclusion is the 3D printed winders Aren't the best for pocket watch mainsprings. So I'm going to buy a bergeon winder Since I expect to be working with this calibre quite a bit.

Once I get some proper oils and cleaning fluids I'll go through again and clean everything. And probably replace the crystal once I decide how I'll deal with the lume.

But for now I managed to get a watch to run within 10 sec/day without causing more damage, so I'm perfectly happy with it as is.

Source a new crystal! That would really make it pop!

Be aware that the lume is radioactive. Take adequate measures to avoid inhaling or swallowing  particles of it

Yeah, I noticed the lume when I was buying the watch, I'm gonna wait until I have the supplies to fully service and replace the crystal before I go through and finish the watch.

I attempted using denture cleaner to hide some of the hairline cracks in the dial, Worked great but also removed all the lume (I knew the risk at least)

Which is great because it now gives me an excuse to try reluming a dial and hands!

That’s going to be quite attractive when complete. Do you know the calibre size? The movement resembles the classic Omega 30t2 in a larger size…

I just finished my first attempt at servicing the watch.

I'm pleased with the results. I did not expect such a good improvement with the amplitude. Found a crack in the balance bridge jewel which is now also on my list of things to fix.

My oiling skills probably need work, and new oil is now on my endlessly growing shopping list.

Four Weeks later, it finally looks finished, Luming the dial went well, the finish is a bit too goldy was hoping for more of a brown.

Looks great compared to how it started though, the hairline cracks in the dial cleaned out well.

Now to find a new watch to work on (Before I decide to have a second go at the lume).

      Tissot case back removal

      By watchweasol · Posted

      The ones I have opened also do not have a pry point , hence the reason for the tool. The watch is clamped in the tool and a blade is screwed into the seam, the blade being chamfered lifts the back then the screw shaft is turned and the back comes off have a look on Ali express for case back removal tools

      I don't think I need to know more about the Orient watch question, so please don't write anything related to the topic, but if you know where I can buy the watch's jewels = rubies and gems shock protection, I would like to know.

      It's an exhibition back so no access as you suggest.

      Phinney Walker Mickey Mouse Watch HELP

      By Mercurial · Posted

      I have no experience with this watch, but looking at the pictures from the ebay listing linked above, it looks like the outer metal bezel at the back of the watch may not be part of the case proper.  It looks like the watch and strap are sandwiched together, and an inner case may push out of the rear bezel towards the front of the watch.  A case style similar to the Roamer watches where the crystal, movement and caseback pushed out through the back of an outer bezel, only in reverse - this one may push out towards the front.  To test this, you would need to hold the watch, dial down, supporting the dial side of the watch around the edge of the bezel without touching the bezel itself. Then push down carefully on the inner metal ring you can see at the back of the watch. I’m speculating here, proceed at your own risk. Hopefully someone with hands on experience of these watches can chime in! Best Regards, Mark

      Thanks, Mark. That's the kind of reassurance many of us wanted to hear! Yes, life is unfortunately unpredictable, and it would be a shame if the many dedicated WRT: ers became stranded if, god forbid, something happened to you and WRT stopped working.
