Hi all,
Just looking for some helpful advice, please and thank you…
I believe this crown looks correct but I’m not an expert.
Do we think this is the correct crown for the reference?
Thanks in advance

And while we’re at it… I’m almost positive the dial is fine but the hands?
Thank you!

Is it a 166.020? I have one with a different dial configuration: photo, more photos. The crown looks like a replacement. The hands too in my eye; they're supposed to have a black part and the hour hand looks too long, but I may be wrong.

Hands look fine as this appears to be a no lume dial. Original crown would be scalloped, but this one might have been a legitimate replacement as the scalloped one was NLA for awhile.

You guys notice the omega and automatic seemingly being uneven?

Agree the dial is original but not in the best shape. Crown is certainly not original.
There’s a lot of DeVilles around in great condition so it’s not a model where one should compromise on quality imo

Those scalloped crowns are my favorite of that whole era, I use them even on some Constellations and early Seamasters which should have clover or decagonal crowns since they’re much easier to grip and pull yet still look good and fit the design of the watch.

@dsio , the scalloped crowns are my favorite too.

Do you have the specifictions of these three crown types....as I have about 15 pieces in steel but I'm not sure of which type

Hi @cristos71 , in my opinion, there are 3 types of scalloped crown which was differentiated by their dimensions.


I posted the information with all three examples here:
https://omegaforums.net/threads/the...onstellation-crowns.54568/page-3#post-2284117

I found this watch (ref. 14770 from omegaenthusiast) with this crown.


Also, I found the reference 166.020 with the same hour-markers pattern.



I believe that “4203” might be the correct one?
@SOG53 , can you measure your crown and share some information?

So if you weren't confused enough already...

The uni-shell cases (14725, 166.020, etc) were originally fitted with crowns which had the female portion of the stem fixed as an integral part of the crown (they didn't unscrew). Crown size and stem length were related to the reference and or caliber family.
