'67 Constellation Spares Advice Please

Lucky67 · Sun. 1:06pm

Last week I bought my birthyear watch & while I'm really happy with it, there are a couple of things I would like to change back to original if possible.
The crown has been replaced somewhere in the past for a generic one and the, original crystal again was replaced somewhere in it's history. I have been looking on eBay and others for a correct crown, but I don't know what size I'm looking for.

And again with the crystal are the ones that had the Omega symbol still available to buy? Any help anyone could offer would be appreciated my '71 Seamaster Cosmic has all it's original parts (as far as I know), & is in much better condition than my Constellation and I would like to see if there is anything I can do to make it more original.

Thanks in advance.

Hello, people here can probably advise, but please start with the reference and some pictures will help too.

There are a couple of threads linking case references and crowns on the forum, you can search it easily. That could be a starting point.

Never have seen case ref 055ST1680005 or 055ST1680050. Are these #'s that Omega uses for parts system? (Never would have thought about same ref having different size crystals.)

Neither of the crystal measurements for 063PZ5016 or 063PZ5171 come close to 31.55MM. Beginning to wonder if I have come upon a counterfeit 168.005.

Kind Regards,
Keith

Hi Keith,

Omega has changed case numbering systems over the years to add another digit. This is why when you look on the Omega vintage database, you often have to add an extra zero. I can look up cases with with 168005, or 1680005, and...

Be careful! There should be a tension ring inside edge of the crystal. They came with gold and silver tension rings depending on the case metal. These have different part numbers.

Also, the lists referenced above are using older part numbers. The parts on these lists may no longer be produced. You may need to check with a watchmaker who has access to Omega’s current parts information to make sure you get something that fits.

Contact wheelers watchmakers in Worthing uk. They’ve just sourced me a 10 sided crown and crystal all original for my pie pan. They’ve got contacts across the globe. Won’t be cheap though

There is a separate thread, noting that the watch is a 168.018.

@Lucky67
If you can find a watchmaker with an Omega account then both the correct crystal and crown should be available from Omega.
