On a lovely Constellation no less!

28034561716_7bc2b36f08_c.jpg

Today my Dad brought the lovely pie pan he inherited from Uncle A. by mean of Aunt G. After being long forgotten, separated forever from its 18K skeleton bracelet, given to my Brother L. who could not care less, it was serviced country side, run for a while, brought back, then stopped again, In a not so pleasant visit Dad took it back from the watchmaker, brought to another smallish town "important watches shop", which could not even open it but said it would have been expensive to repair, so Dad gave it to me to find the best place to be repaired. He wanted to get at least an estimate by the official service center, which I opposed strenuously, suggesting instead to have it repaired in the UK. Of course the mutual agreement was that I would not touch it. But he wanted me to at least open it, and we both remained very impressed by the beauty and shades of the 551 rhodium plated movement, swan neck regulator, and that there were no cow hair

After dinner, and with the watch opened on the bench all good proposition did not last long. I noticed that blowing air the balance would move one way only, in fact it seemed like the impulse pin somehow had ended on the wrong side (is that even possible ?). Took auto auto bridge off, lifted and reseated balance and cock, and it would run for few seconds. I then fiddled with crown in, out and midway, and it started running! Anyway, it definitely needs a professional hand ASAP.

  • Should I tell Dad it "mysteriously" started running again?

I guess if it runs for a while there is not a lot amiss. It will need stripping & all parts inspected & then cleaned. The issue you might find is if spare parts are required they are becoming increasingly difficult to source.

To understand what would normally prevent the roller jewel from ending up on the wrong side I have a link to a video.

If you're lucky the last watchmaker just put the balance wheel in the wrong position if you're unlucky somebody broke something they weren't supposed to.  I agree finding parts for older Omega watches or basically any older watch is becoming quite a challenge. Watches like Omega because they were expensive now the parts tend to be very expensive if you can find them at all.

Then link to a website you can find a authorized service  and the official price to get it serviced is cheap.

As mentioned it works continuously now.

Thanks for the video. When the watchmaker last serviced the watch it was working, hence at that time the impulse pin was sitting correctly, as it is now.

BTW I do not find the servicing prices by Omega to be cheap at all [emoji15]

All pretty debatable, for a high end swiss manufacturer it's not too bad, especially as I believe case (and bracelet if applicable) are usually fully refurbed with every service.

But a non official workshop/watchmaker without refurb might service something like this for around half the price.

Nitpick, let's remember that Omega, just like Rolex, it's not an high-end brand. It's a leading/large volume maker. High-end.. depends who do you ask, for some not even Patek is.

True, I guess i don't know what I'd call patek phillip or lets go even higher, say R.W.Smith if I'm calling Omega high end, though I do have respect for Omega and their standards.

    • If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem. 
    • How long had it been without any wind before you first put it on the timegrapher?  Perhaps there was some debris / old lubricant that loosened up while you were waiting to do the 24 hour reading? I recently serviced a Seiko 6319 that immediately after service was absolutely horrible on the timegrapher - 24 hours later (without me doing anything) it was rock solid!  I was a little surprised by this (as I have seen improvements in amplitude after letting it run in but never a watch going from useless to great!). I was suspicious that some dirt must still be in there so I took it apart and cleaned and lubcricated it again and had exactly the same experience - snow storm that after some hours turned into a nice straigh line with good amplitude 🤷‍♂️
    • Yes, I know it was able to run before just enough that everything supposed to be affixed with shellac could fall out. I won't get back to work on this watch for several days at least, but one thing you mentioned about the banking pin adjustments being intended for fork horn clearance got me wondering.... The last adjustment I made to the entry stone yesterday did not solve the problem when the balance is installed. The escape teeth can't quite clear the stone when the balance swings. But I thought it was going to work because manually snapping the fork back and forth did allow the escape wheel to advance almost all the time. I wonder if there's another issue with the impulse jewel, that I have to shellac again anyway. I am going to measure the fork slot and the jewel because I am curious if it is the right size or possibly narrower than it should be. My thinking is if the horn clearance is too great maybe it is not getting enough impulse to clear the escape tooth. But pushing the fork with a tool can move it far enough to clear the escape wheel tooth.  I'll see later in the week. I didn't expect a big challenge from this watch because it ticked for 5 minutes before stopping without shellac. As always I was way wrong.
    • I had one success (and one failure) dissolving a broken stem out of a crown with Alum. The successes was a stainless steel crown and a milder steel stem. A Tag Heuer 2000 Automatic - here with the solution at around 60ºC I could see small bubbles coming up from the stump of the stem and it took maybe 6 hours to disolve I tried to repeat this with another watch and it did nothing.....  This was A Bulova Ambassador with what again looked like a stainless steel crown.  
    • That good to know in one way.
