Good morning to everyone!

This is my first message here.

Thank you for this great post which helps very much to collectors and enthusiasts like me.

I bought last year an Omega Seamaster De Ville Automatic Ref. BA 166.5020 to a gentleman from UK. See photos attached.

According to its serial number, it dates back from ca. 1965. The dial color and configuration is quite special, I haven't seen one like this before.

Would you say it is a redial? According to my knnowledge, I would say it is original.

Thank you for your help!

All the best!

Thank you so much for your quick reply and a pleasure to talk to you!

I'm very happy that you confirm this to me. It is a grey/blue dial that looks awesome. Not only the color but the dial configuration is quite rare too, with the printed OMEGA words and the applied 12 and 6 numerals, isn't it?

I'm now about to replace the plexi with a genuine Omega with a ciclops at 3, ordered to Omega Switzerland specifically for this reference. Perhaps the one it has is original albeit not having the Omega logo in the center?

All the best!

As my dial (see post above) resembles the 12 and 6 configuration, do you think my watch might be from the same year/origin?
In fact it's the first two watches I've seen with 12 and 6 only, missing the 9....

Very nice timepiece indeed!

It could be from the same year/origin. To confirm it you must check the reference in the inner case back and the serial number in the movement.

It might be an amateur question.... How do you properly open the case? On the back it says "waterproof" in my case, does that make a difference?

This specific model has a monobloc case, meaning it can only be opened from the top.

For example, to be able to see the reference in the inner caseback you should remove the outer bezel, plexi, dial and movement.

As I'm not a professional watchmaker, I always trust on my watchmaker to do it.

I can’t believe I missed this amazing thread. This was found in the belongings of my wife’s late grandfather. Solid gold I believe, although hallmarks are difficult to make out even under a loupe.
The dial is slightly different to most in having dashes either side of T Swiss Made T

Hello everyone. Hoping someone could shine some light on this watch I was told was my grandpas?

I am not sure if it is authentic or there could be parts that were put together? Any help would be appreciated! thank you.

I just found this site, and I am not seeing what I happen to have in my hands. I just found a Seamaster Automatic De Ville Day/Date in a box of my dad's. I just went through this forum looking at fabulous watches, but I don't see a single Day/Date, so I'm starting to think it might be a fake. I do see that American references show a C 6864: automatic, day, date, cal. 1020 (1970's). I'm willing to put money into it and restore it, as it needs a polished/replacement crystal and is missing the crown. It is not a unibody, as the back unscrews. It runs, the day and date switched properly, and I was able to use a pair of needle nose pliers to quickset the day and date and set the time. Is this a real Omega? Sorry that I can't give any internal photos as I don't know how to remove the caseback. Thanks to you all in advance. View attachment 1795841 View attachment 1795842

Just polished out most of the scratches on the crystal. I found the Omega "logo" on the underside of the crystal, so it looks like it's a real Omega.

Now that this watch is running well and I've polished the crystal, it needs a crown, and possibly a stem. I live in the San Francisco Bay Area; does anybody have a suggestion as to who could do this work? Thank you.

My jeweler opened up the case and the case says it is made by "Star Watch Case Company" "C-6357". It also shows a Serial Number "37389416" and says Swiss Made 1020. Omega has no record of this SN and this thread doesn't refer to the Star Watch Case Co. at all. Frankly, other than a large Omega logo imprinted in the works, this doesn't look like the guts of any Seamaster that I've seen opened up, on any site. I don't know what I'm looking at. Any help would be appreciated.

You have an American market Seamaster ca 1973.

This thread is almost exclusively for the earlier Seamaster DE VILLE with the 5xx movements.

This second generation aren't particularly prized or interesting as they are rather plain in comparison the the variety of unique dials offered on the previous generation of watches.

Thank you for your help. I've ordered a crown for it and it looks like my local jeweler can install it and the stem if necessary. I'll continue to polish the crystal to try and get the last of the scratches out. The bezel and the rest of the watch aren't in great shape but as far as making it look very good again and seeing that the day/date and timekeeping are working perfectly, I think my brother will be very happy to wear it...and I'll instruct him to always put it on the winder at night!

What a crazy thread! Really admire your work man. However I have one question. I recently acquired a LL6590-1 but it comes with a 563 movement and the dial possibly from the KM6339. Can it be a dial and movement swap?

Here are some pics:

Since the LL6590 is a no date reference I would say you have a franken watch.
