Documentation on Omega 211 movement


Recommended Posts

I'm timing a 1950s Omega 211 ladies' movement and trying to find accurate info on the frequency.

The listing at Ranfft shows 18,000, but looking at the ticks on Watch-o-scope it's beating at 21,600. Someone on the Facebook group said it should be 21,306.

Is there a reliable/trusted source for this kind of movement info? I found lift angles at watchguy.co.uk, and found a parts diagram on Cousins UK for the Omega 210, but no frequency info. I don't mind paying for books or services, I just don't know where to look.

I was hoping to start there before taking the movement back apart to count teeth, or chase down a problem that doesn't exist.

Is that something available to the layperson?

documentation for the various watch companies over the years is an interesting subject.

if you're lucky for your watch it might be able to find a parts list. Depending upon who made the watch when it was made etc. it might even be some sort of technical documentation. Then the companies also had supplemental information which is much harder to find. Such as Omega currently calls them working instructions to understand what they look like I have a link below. Omega even now has general information that covers groupings of calibers with information related to that particular group. Simplistically that means if you get a technical sheet on servicing a watch it's probably missing information because you're supposed to have the supplemental document that sometimes isn't even referenced in the technical document. I do notice now the companies are getting better at referencing that you should have this other documentation.

now for your original question the answer is no you're not going to get working instruction 28. To understand this I have a link the cousins were searched for the word working. You'll notice that they have a few number 40 is a nice one to download along with any of the others that you like. So open up the PDF and noticed that every single page corner is watermarked with who downloaded it. So one time cousins had access to Omega documentation has its watermarked that way. Problem is if the watch company is so paranoid over who sees her gets her documentation what happens if the documentation's week in the wild? So basically anyone who has access to documentation is going to be extremely restrictive on who sees it. Of you lucky some kind soul might snip something out for you. Conveniently skipping over how I managed to get the documentation and why I'm not going to endanger the source that it came from.

oh and then just in case you didn't have them I have the parts list for your watch. The reason 210 is there is it's the base caliber

    • Hi nickelsilver, thanks for the great explanation and the links! I'll take a good look in the article.  Especially this is great news to hear! Looking through forums and youtube videos I was informed to 'fist find a case and then fit a movement for it'. But seems that's not the case for pocket watches at least?  I guess I should be looking to find some 'male square bench keys' for now. I was thinking of winding the mainspring using a screwdriver directly, but I found a thread that you've replied on, saying that it could damage the spring. 
    • Murks, The rate and amplitude look OK, and the amplitude should improve once the oils you have used get a chance to move bed-in, also I notice that you are using default 52 degrees for the lift angle, if you get the real lift angle (assuming it's not actually 52) this will change your amplitude - maybe higher, maybe lower. I notice that the beat error is a little high, but not crazy high. At the risk of upsetting the purists, if the balance has an adjustment arm I would go ahead and try and get this <0.3 ms, but if it does not have an adjustable arm then I would probably leave well alone. Just my opinion.
    • Hi everyone on my timegrapher it showing this do a make anymore adjustment someone let me know ?    
    • Maybe I'm over simplifying this and I'm a little late to the discussion, but just by my looking at oil when I use it on a treated cap jewel  the oil stays in one nice bubble, but when I don't it spreads out to the edges of the jewel. I'm not sure (but could well be wrong) but the analogy of a waxed car and rain is accurate in this case, the wax is very hydrophobic and repels the water, however, the process epilame works by is a different physical process based upon cohesion/adhesion (oleophilic) not repulsion (oleophobic)  at least as far as I have read/observed. If one were to use a oleophobic substance equivalent to wax (hydrophobic) then one would need to create a donut shape to fence in the oil, however if one used such a strategy with a epilame which is oleophilic then the oil would sit on the ring of the donut and not in the 'donut hole', exactly where you don't want it. Even if the oil is smeared then the oleophilic epilame should pull it back to the center (see diagram below). Reference For interest the chemical in epilame is 2-(PERFLUOROHEXYL) ETHYL METHACRYLATE, CAS NO: 2144-53-8
    • Looks lint the teeth on the hour wheel aren't meshing with the teeth on the calendar intermediate wheel, maybe the hour wheel is sitting on top of this instead of meshing?
