Omega Info Required


Recommended Posts

Hi all,

I recently purchased a 1962 Omega ladies watch which has a cal. 455 automatic movement. It's a Ladymatic in a square case. The information inside on the case back ties up with the movement serial number. The crystal, which has yellowed a bit and is cushion shaped and curved on all four sides, I'll need to replace. It's working fine but I will give it a service though.

The point of sale information described the watch as an Omega Redima Tick. Can someone please explain to me what that means because I cannot find out much about it?

The movement serial number is: 19008899, which dates it to 1962

I don't want to upload any photos because I don't want them on the WWW just yet,  but inside the case back is engraved:

  • ACIER INOXYDABLE
  • OMEGA WATCH CO. (inside a triangle)
  • FAB. SUISSE
  • SWISS MADE
  • 3993 62 SC

Thanks in advance.

I've worked it out. There's a recent version of the Omega Ladymatic model called Redima Tick.

The seller of the one I purchased used that model info for the Ladymatic I purchased.

What I need to do now is find a replacement crystal for it.

Does anyone know where I can get a replacement crystal for this. It's cushion one, inside and out, with a flange so it can be glued in from inside the case. The bezel aperture is 17.5mm x 17.5mm?

Cousins sell it: code number RX1731734 or RX1741744 or RX1751754

Thanks.

I think. but I stand to be corrected, that the RX is for inset fitting into the front of the bezel. The type in this watch is an underlayed type, i.e. with a flange for fitting from inside and gluing into place.

Yes RX is front fitting, but with a little care with a file or a mill they can be reshaped to be rear fitting. I have done this a couple of times with curvex watches. Hence my suggested range of sizes. The corners have to be rounded also. Otherwise you need the correct Omega part.

Hmm, I still do not think it's possible. I'm not sure of the name of this type of crystal. Probably 'underlayed capsule' or 'cylinder' type, or something like that. Here's a freehand cross section of it:

If you give the correct numbers to your supplier, you will obtain the correct glass. Just clean the whole case, use a little crystal cement when fitting the glass it should just press in. The old glass are you sure it is an Omega glass, a genuine Omega glass has the insignia in the middle.

Cousins cannot obtain it, it's to do with the ongoing Swatch problem, I gave then the model number which is 3993 62 SC.

As for the Omega insignia, the watch was made in 1962. Maybe they didn't do that then.

This can be made from an RX crystal. I have done it. Milling or filing and then polishing - you only need shallow lip and the dimensioning is crucial. But it is a tricky job - better left to the professional.

    • As far as I know, the only time an epilame treatment has potential drawbacks is when something is rubbing on the treated part w/o lubrication in between creating abrasive dust. That is, I don't believe in the method of "running the watch to make a groove through it first in the pallet stones where the lubrication is then placed". So, I think the rule would be; do not epilame treat parts where rubbing is going on without lubrication. Other than that I don't think we have anything to worry about. That said, I'm not an expert, and I'm always happy to learn more. Has any other repairer than Alex suggested or explained the "making-a-groove" method? My impression is that it's just something he constructed in his mind. I have not perceived it as a generally practiced method. Again, I could be wrong!
    • Post some pictures , some good close ones of the parts you've described. 
    • Ive never used epilame H only information i have read and mentally stored about it mostly from Nicklesilver here and elsewhere ( the fork horns thing ), maybe the residue powder that is removed has some grinding effect ? So probably a good idea to limit its application areas to only the absolute necessary. Yes as far as i know epilame rubs off relatively easy, the technique of running the watch to make a groove through it first in the pallet stones where the lubrication is then placed. This i understand creates the barrier for the lube to sit up to. If i can find a good balance of pros and cons of its use then thats one process i can avoid by using a thixotropic lube on the stones. The epilame i would say allows for a more fluid lubrication to be used that would increase amplitude on low beat movements. The stearic acid powder is extremely cheap, the problem is the fuming process to coat parts, is not selective , the whole part has to treated in this method. If epilame residue can cause wear then thats not good, if I remember the conclusion was not proved entirely just a general assumption between watchmakers. The thread is out there somewhere, the same discussion is also old on a facebook group.

    • Following on from my question about identifying screws in the AS2063 movement that basically fell out of the case in bits, I’m pleased to report that I’ve got it all back together, and the movement is running pretty well.    But… There’s something wrong with the keyless works and hand setting. It’s fine in winding and quickset date position - these work - but in hand setting position winding the crown turns the whole gear train.  I don’t really understand how it’s meant to work. It doesn’t have a traditional friction fit cannon pinion.  The second wheel is unusual with a pair of smaller pinions on it, which seem to interact with the barrel and the motion works.    Could this be the problem? I must admit I just cleaned it and popped it in place when reassembling the gear train. I’ve lubricated the pivots but didn’t do anything to the extra bits on the second wheel.    Does this make sense and is anyone able to figure out what I’m doing wrong? Thanks in advance, as always.    ETA - the parts list calls it the Great Wheel, not second wheel. 
    • You're thinking metal to jewel in general I guess. Maybe it would be a good idea to peg the pallet staff jewel hole on the main plate after the epilame treatment. I think that could work as it is my impression that the epilame doesn't sit very hard, but I could be wrong about that so feel free to educate me. I didn't remember that 9501 was thixotropic (thanks for the link). That would mean it's even runnier during impact (lower viscosity) so perhaps it's time I get some fresh grease as mine seems a bit too runny. What I have seen is a whitish surface after washing but it goes away if I scrub the surface with a brush in a degreaser (Horosolv). I don't think it embeds itself in the metal but sticks very hard to the metal. I don't worry too much about the cleaning solution. I just want perfectly clean parts and my solution can be replaced for little money (ELMA RED 1:9). Anyway, I quite often need "to strip back and rebuild" and scrubbing parts by hand isn't exactly the most stimulating part of a service. Just got confirmation that Moebius 9501 has a lower viscosity (68 cSt at 20° C) than 9504 (305 cSt at 20°). The viscosity of Molykote DX is 285-315 cSt at -25° to +125° C. I was surprised to see that the viscosity of Moebius 9010 (thin oil!) is higher (150 cSt at 20°) than my 9501 grease!
