Omega 552 installation of second hand


Recommended Posts

Hello to all.

I'm working on a vintage Omega de Ville.

Almost finished the servicing of its beautiful 552 caliber.

I'm wondering what is the best way to install the second hand concerning not to damage the very delicate sweeping second pinion spring.

Does somebody want to share his experience with me please?

Thank you very much.

Regards Jack.

Hi  If you have not got the appropriate movement holder with the support screw you will need to place it on a heed surface to provide the support and be very gentle.             https://www.watchuseek.com/threads/mounting-sweep-second-hand-on-omega-565-movement.969330/             There are many hints and tips to be found on this link.

From memory (but i'd have to look at the underside of a rotor bridge first), you can possibly attach the auto mechanism which supports the spring to some degree. But the ideal thing would be to use a support as WW mentions.

If you have one of the Horotec Rolex movement holders (I can't remember if it was the 1570 one or the 3035/3135) they work great for support while attaching the seconds hand.

Thank you very much watchfellow!

    • I'll go halves with them John , we can share it 😉
    • Besides locktite Nev, is there anything random that you use to fix in the pivot ?
    • Thanks Hector, I do think though that the problem I am experiencing is specific to Miyota movement in general and the 6T series in particular.  When you describe putting the bridge you are talking about the train wheels.  The problem here is that under that same bridge you have the 4 train wheel, the barrel, 2 extra winding related wheels and the center sweep pinion.  I can mostly put them in their holes but 2 of those (the 4th wheel and the second pinion are completely under the plate so I can't nudge them in the right position.   I managed it with a larger Miyota 8200 series but with the smaller 6T15 it is even worse. Anyway, I'll retry tomorrow evening or this week end.  This evening is going another rock climbing day (going from very light pressure on tweezers to much more force going through the fingers, although in climbing we also want to use the absolute minimum grip which won't make us fall to save the muscle and be able to climb longer routes). to add insults to injury, if you read this thread from the start, I initially messed up the disassembly as I couldn't detach the rotor.  I normally (and I think I did this time too) put all my parts in their individual compartments in the part tray and I am doing my best to be very careful about them.  But in the week and a half it took to figure out how to detach the rotor I somehow lost the screws from the bridge.  I have a few others which will be needed later.  I know they are reference 922-600 but I couldn't find what it means in general term so I don't know if I can buy replacements or an assortment of screws and replace those 2 by others.
    • Something that can happen with a lyre spring, the back of the arms can bind against the shoulders of the chaton cut out where the spring is fixed in when the spring is lifted out of the way. To stop the spring bending or breaking it needs pulling forward slightly before lifting so it clears the edge of the chaton.
    • One way is to file it by hand. Good file with sharp edge is needed. Another way is with the aid of milling attachment. There is one more way, thyat is really only on the lathe, but the arbor has to be attached perpendicular to the axis of the spindle. Will be easier to show pictures than to explain this. I must say 'Good night' as my wife is now awake and is roaring when I get closer to the computer...
