      Hi all
      It has been a great challenge to find a Omega Case tube for my Seamaster Chronograph Professional case 178.0504 (or 178.0514).
      Omega part number is 090ST1237.
      Any place I can buy an alternative after market to replace the original? any suggestion on where you would go for an Omega like after market case tube?
      It is quite a long tube (5.90mm) threaded in the inside.
      Many thanks

      Hello all,
      I know it's 'only' an electrical one but to say I'm overjoyed is a bit of an understatement.
      My Grandfather gave me this, his 1982 retirement watch, 20 years ago as an empty case and strap - the innards had apperently been slowly demolished over the years by a leaky battery and where nowhere to be found.
      At the start of the locky-down thing I decided it was time to do a bit of research to see if the parts could be found to rebuild it, bit of a baptism of fire as a total newby. It soon became evident that this search should have been done years ago because Omega restricted parts coupled with a dearth of NOS parts was a real headache! 
      Through all this research I also realised just how rare the case and bracelet style were so persisted for months, getting my claws on some old, rough, nasty and for want of a better word, crap bits and pieces. As we know the circuit and coil are getting really rare but even more rare it seems are the winding pinions and dials for them, and even the crap parts are ludicrously expensive. You know how you get into something, buy bits, realise your up to your neck in it but realise you're to far in it to retreat?
      Suffice to say, I've had so much support from several people in the watchmaker community so with their help and shear dogged, billigerence and blatant stubbornness it is finally running. Still some work to do -  the date needs to start changing at half 11 because it takes two hours to change, the seconds hand needs lining up better with the minute markers and I've toyed with the idea of restoring the dial, with some lacquer and minute markers missing (or maybe not, as it's a sign of its individuality!) 
      Having enjoyed it for a while I'll also take it all apart again and service it, only because of Lawson''s brilliant walk-through on the 1337 movement on this forum. 
      Never really thought of a bi-colour watch like this as my style, but with the blood, sweat, tears and more sweat and tears that has gone into it, I've decided I love it to bits. Thank you all for your never ending inspiration and such generous shared knowledge Mark Lovick and everyone - great bunch of people you lot!

      Got a ladies Omega De Ville in an auction lot today. My limit for repairs to this point has been installing batteries. The watch runs but runs several hours fast. 
      I know there are a few reasons it could be running fast. I don't have a degausser but suspect it could be magnetized. 
      What are some other things I should consider or questions I should ask if I take it in for repair?
      Also, do you know if there was originally a plastic retaining ring to secure the movement in the case? There was none when I opened the back.
       
      Thanks in advance!

      Hello!
      Not sure if this is the right place for my question since I do not intend to do the repair myself. However I am wondering if anyone knows an approximate price of a tachymeter for the Omega 3520.50 day-date (tripple date).
      If anyone has any idea what a insert and the "repair" would cost at a watch shop, please let me know.
      Thanks in advance.

      Hello. 
      I am about to work on a Omega ladies automatic watch.
      I found out that the axis of the rotor is out of place and shakes up and down.
      What could be done in this situation?
      Thanks!

    • I'm following this. Case restoration is most important its knowing when to stop as it is easy to damage what has built up over the years. 
    • If you look at the link of the pocketwatch database for the serial number and you go to the parts list you can go to Springs and I snipped out an image. So we have an Elgin part number and a strength as an added bonus you click on the part number and you get this link https://pocketwatchdatabase.com/search/result/elgin/9785822/parts/catalog/X791/250 Fortunately it looks like that particular hairspring goes in a lot of different watches. That's the good news the bad news is we still have to find one and you're going to have to play with the screws to bring it in to time. When I get a chance I'll go look at my Elgin parts catalog and see what it says about the hairspring if there's any other additional information. Then that is assuming that it just needs a hairspring and that it doesn't have a broken balance staff more than likely it's going to need a main spraying and if you're lucky that's all that's going to be wrong with. I don't like when parts are missing like any parts it suggests other things could be missing were not even right. As one of the cautions of buying off of eBay it might look nice and pretty in the picture but in real life that doesn't always agree with the pictures. On the other hand the watch that I bought that wasn't quite what should be scrapped for parts because I really needed one of the parts off the watch so it worked out at the end.    
    • Dr ranfft shows 18 size HS to have come both in flat and berguet. Will you show a side view close up of the balance? I suppose you can go by serial No as well to find out the hairspring type.  Building the complete balance on these is challanging. 
    • In case anyone is having trouble curing their UV cure products, check the UV curing light. Most nail curing lights are using UVA leds with a wavelength of 365 to 405nm. These tend to have a low output and some manufacturers apply higher currents than recommended to increase output. This unfortunately will shorten the lifespan of the LED. The bad news is it will still lights up but the useful UVA part of the spectrum is gone. Hence your varnish or glue won't cure properly. Another problem is using a dental curing light for curing UV gels. Our dental curing lights are actually using blue light with a wavelength of 450nm. There is absolutely no no UVA. It is designed to be safer for eyes. Hope this info helps.
    • Yes that is a problem but unlike when I try to point out that swapping hairsprings is a bad idea and it typically falls on deaf ears on this group this is an American pocket watch. Providing nothing else is wrong and if the hairspring truly is missing it's not like it fell out all by itself which then makes other things suspicious that they could be bad. But providing it's the only thing that's gone missing in this watch it can be replaced. American pocket watches were some of a few watches that hairsprings are available as a separate component. Although finding one and the associated timing screws to bring it in to time will be an interesting challenge but not impossible. Then it's a shame it wasn't a 16 size? 16 size is a much better watch to start playing with 18 size has some interesting challenges but still a watch somebody can still taken apart with caution and before the original poster does so I will explain some cautions before taking it apart to avoid unpleasant surprises and damage.
