I'm on the look for a good example... which are the reference numbers for those featuring the 3D star? Is there a code name for those?

All of you that already have one, enjoy it in good health!

so you're saying i should change the crown and crystal?
Make sure that your watchmaker can get the original crown. A lot of the old crowns have 'replacement crown' part numbers now. It will be genuine Omega, but it will not be the same as the original crown. Be sure you confirm that the crown will be the same one before you direct the watchmaker to replace it. You are better off hunting for a original crown in better shape, or keeping the existing one, if the Omega 'replacement' differs from the original. If you decide to keep the original crown, the gasket can be replaced if needed.

From the Ofrei site Genuine Omega Crown Yellow 069SX42522
"Crowns numbers 42050 replaced by 42522
In 1988 the Omega cross reference number was ST42050 for this genuine Omega crown. Today in the year 2007 Omega says that crown LA42050 is no longer and is equal to SX42522. Diameter 3.75 and height 2.7."

Here is a listing for the original crown that is no longer in production. https://www.ebay.com/itm/Omega-Crow...287828&hash=item1c6782747b:g:V9oAAOSwSWJXQ6Tl

@Archer can you confirm this?

I would. It is fairly common to use a recommended replacement crown. But, if you want to keep the watch completely original, it would be best to get the original crown. I made the same mistake on one of my Seamsters and spent a year looking for the proper crown.

Nice topic. I’ve got a fluted/grey/steel one too.

The black elements are onyx, correct?

My first vintage piece. A beautiful C with a fluted bezel and linen dial. I was looking at old seamasters and piepans when this came up in my recommended. Was helped greatly by the folks here on OF and got a real bargain.

If you haven’t already, give it the respect it deserves and treat it to a service. Find a watchmaker you trust and do it soon- it always starts with just one. 😉

It has indeed been serviced. Running very well too, the service took only a couple weeks of wait but the proper crown took months to come in.

I have no doubt I won't stop at just one. Unfortunately for me I have an attraction to vintage seamaster divers. (The asymmetrical case with sword hands particularly). And that is an undertaking that I am absolutely not ready for. Perhaps a 1st gen planet ocean will temper my desires.

Way to aim high! There are lots of threads on the Seamaster 300 of which I believe you speak- and many pitfalls- so education is your best friend.

Definitely an intimidating piece to even consider. But oh so beautiful. I think Omega are really missing out by not having a modern equivalent in the current lineup. I mean planet oceans are cool, but these new ones are real chunky, and I've got a small wrist as is.

I actually know the feeling, while it is my very first vintage watch and I felt in love with the dial 😉 Omega Constellation 168.029 Cal. 751 and I love it and this Connie will always be my first! 😉

Hi, while I was looking for a nice „Pie Pan“ constellation for my wife, I found this:


this one isn’t a beauty but the price was incredible good, so I had to buy it.
Unfortunately it’s not working at the moment (which doesn’t surprise me, because it was probably the dirtiest watch I’ve ever received.
Somehow I found this one interesting anyway

Wow, congrats on your purchase. That looks really cool. I have seen a few Omegas from the 70s and 80s with portuguese day-date functions in my homecountry Brazil but never any in any asian language that was not japanese.

A korean Omega. I think many collectors in South-Korea would find this very interesting and collectible.

Lemme know if you wanna sell it. One of my Korean fellow watch hunter pals in NYC would be a sucker for it and I can make him a deal he won't soon forget 😁

Thanks, did some research on the watch, it seems that this version is actually quiet rare. It is not from South Korea, it is from the north. The red letters on the dial mean Kim-Sung II, the name of the leader of the country at these times.
Ok, he wasn’t Ghandi but still collectible, I think.

Next thing I’ll do is get an extract from the archive and have it serviced.

Tried to remove the bracelet, but no chance. It is a end link no. 736 ( mounted on a common 1172 bracelet), I couldn’t find a another reference with those . Do you know one ?
(Because I think the end links have to be bend in order to get them removed, and I don’t want to do it if they are too rare / hard to get).

Try soaking the ends of the spring bars with WD40 or penetrating oil of some kind. Naptha is another possibility to loosen up the corrosion. It’s messy but doesn’t harm any finishes.
