Reposting Al's response from 12 years ago on another forum:



I think Omega sells the pushers as one piece, so I don't think there is a part number for the springs.

and this should be the case back gasket but 176.0012 doesn’t show up with the list of ref's .

Also ,
What would you say is a fair price to pay for a new set of hands ?
I only need the time hour\minute and chrono seconds but might go for a full set

I wouldn't trust eBay in this case. Who knows what the seller's description is based off of?

My guess is 088NS0039 is the middle gasket. Cousins shows it is for 176.0012 here and calls it the bezel gasket:



Here is the 088NS5091 on Cousins for the case back:



I don't know what would be a reasonable amount to pay for a set of hands.

I don't know what would be a reasonable amount to pay for a set of hands.
Hands in general are priced all over the place. Best to restore if possible.

I got a set of hands that were designated for 565 dynamic. I think for around 60 or so. They did not fit as they are for a larger movement like my chronostop. Or something similar.

I have seen hands listed in the hundreds, even the thousands. Of course who knows if these ever really go for that.

I have paid in the 30s for three hander hands. With job lots all bets are off. Sometimes there is a loose hand here and there. The Omega stuff does not show up in job lots much. Those are mostly landeron, Valjoux and Venus in that order. Lemania, is often pure unobtanium. I have been looking for a 105 hour hand for 3 years or is it thirty? Sometimes Tissot works as an alternitive, although it looks like there were efforts to keept the designs separate.

I have been attempting to replicate some of the YT vids using a laser to cut hands from thin razor blades. Main issue is warping and heat treating, which is why restoring may be a better option. Have not attempted to laser weld a hand yet. Theoretically possible.

Lumes and vapor deposit finishes are going to be much more difficult. Which is true of any of this.

There really is no way to define a reasonable amount of what any embargoed part will cost. That is pretty much the point of the embargo. Which is to control markets and restrict trade. Free trade is basically an orwellan term, and could mean anything from barter to black markets to outright theft. Does free trade give one the ability to embargo things which are restrictive or anti competitive. How many greedy people then are in favor of 'free trade' for those reasons. Same things could be said of freeways which are now called expressways or interstates, and no longer free.

Thank you for the thorough answer , at first i thought i could save the original hands by either cleaning or completely repaint them .
but removing them ended with a broken chrono second hand which was rusted into place .
maybe the time hour and minutes can be saved with a lot of work . the rest are ok .

Minute and hour hand aren’t that expensive but there isn’t a second hand for sale other then buying a set .
saw a new set for 350 + shipping which sound a bit high but i could be wrong .
theres a incomplete set of used hands in bad shape for 100+ shipping which could be restored .

those are my watch hands:

and the movement , where you can see the center of the hand still in place :
(looks like there is some rust on the motion side but hopefully not to much , this as far as i got by now )

Yeh, I have the same issues with the wedge shaped Dynamic hands.

Such a shape would be a good candidate for laser cutting. They do though tend to turn up from time to time. A lot of the sweeps tend to use similar pivot sizes. There is also the issue when sellers really have no idea of what the hand really goes to. So selling as a set is probably easier.

350 is not an unreasonable asking price. Outside my league though. Most of the time though the listings tend to recycle. Then one day it is gone.

Bushing hands is something I need to work on. At least the material is soft, so in theory one can make the small pivot drills. I have the lathe. I also got a lot of grinding and dressing wheels.

Somewhere in my thousands of posts I did an experiment with using foil transfer to guild an old scrap hand. This transfer was intended for firing onto ceramic coffee mugs. Also had a use as a base for toner transfer PC boards.

I sometimes forget I have 24 or 25 landeron movements, which is what the dial printing machine is ultimately destined for. I actually got one of the oFrie hand assortments, which did have quite a few wedge hands in them. As I recall they are all red. They are also a bit on the long side as the modern popular crap wants large blingy dials.

I agree that 350 is reasonable , but it is a large amount of money . buying a full set of hands wasn’t a part of my plan .
i'm not in a rush , so i will check all of my opinions .

in the original hand , is the tube welded on ? the shape reminds a rivet process .

Please note that the numbers I’ve provided for these parts come directly from Omega. If some third party vendor has them identified differently, we’ll personally I trust Omega to know their own products more than a third party...

for future search results for 4.5 restoration purposes I ordered the same gaskets, crystal, etc using Archer's numbers from 12 years ago (which Rendo dug up and shared), Cousins, and TMWatchCo (which I'll post back on after I install).

also bought the crystal and the L shaped gasket from TMWatchCo , haven’t used them yet but looks good .

TBH I think theres might be another gasket not mentioned above , while dismantling my watch I found 4 gaskets .
1. case back gasket.
2. Middle case gasket ( i think it is used to hold the 2 case parts together )
3. L shaped crystal gasket .
4. on the black metal ring that holds the L shape in place i took out another gasket .

and when reading the old @Archer post ,on the first gasket he mentioned that on the diagram it looks like it is placed under the crystal .
and that could make sense with the fact the gasket on eBay was listed as a crystal gasket .

added some photos :
