Does anyone know of a good source for OEM Omega crystals?  I’m trying to source an Omega PZ5200 but every supplier that lists it notes that it is restricted and not available to mere amateurs like me.  Just wondered if I was missing anything other than surfing on ebay.  Thanks all

Hi The reason why they are restricted is because they come under the SWATCH banner who will not release parts only to their agents. Independent watchmakers/repairers miss out. As pointed out by LWS they do crop up as NOS on ebay so thats the place to look.    Generic ones can be got from the material houses like Cousins, Jules Borel, Esslingers , AG Thomas.          cheers

The other thing you want to consider: Does it >>HAVE<< to be Omega?

If what you need is a sapphire crystal of a specific diameter with a specific dome and (possibly) a specific ring, just look for that. Unless there is something specific that will identify the crystal as being an Omega crystal (an etched logo for instance) a generic replacement will work.

If you have contracted to service a customer's watch and told them you'd replace the crystal, that's another story - but you would have had to include the cost (which you didn't know) into the cost of the service. So I'm guessing that isn't the case.

      Vintage pocket watches from e-bay (winding stems needed)

      By Mallard · Posted

      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.

      Epilame / Fixodrop

      By Waggy · Posted

      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?
