I could really use a second opinion on this one. I have compared the watch dial below to one sold on the forum about four years ago (second photo). The 'S' in Seamaster looks different that the example I am comparing it too. I have seen examples of both styles of 'S' in the past, but I think the style was on older watches. Not sure if I am right, but is one a 'coathanger?' Anyway, any input is greatly appreciated.

 

The bottom SM with the normal S looks like a 166.010

U could open both caseback to check the reference number.

Also if u could provide macros of the dial it would be great so we can give a clearer look at the dial if it's a redial or not.

 

Typo?

 

166.010!

My bad.

 

The top one is a166.009. Both watches are 1966 by their serial numbers. I will see if I can get macros but this is the best of the photos in the listing

 

Looks like a redial to me.

G in omega looks too thick and misaligned from the rest.

 

Two threads on the same watch ?

Looks like it. I searched the forums for watches like it, but apparently not well enough. Looks like I searched for the reference number without the period in it. Going back to the 'S,' it is the same style on my '59 crosshair dial. So redial, and 'Seamster' was from the wrong timeframe.
Thanks everyone. Regrets for the additional thread.

 

Are they both redial, or is it just the top one being a redial?

 

Here it the original for sale listing. https://omegaforums.net/threads/196...-seamaster-166-010-with-box-and-papers.29489/
The bottom one is described as "Dial - original crosshair dial with onyx markers. Some patina/spotting. This is most visible when tilted at a certain angle. Looks beautiful on the wrist." I chose it as an example that was known to be original when doing my comparison.

 

The top one is a redial. The cross hairs don't extend beyond the indices.

 

And the case is polished and I doubt the crown is correct.

 

I've encountered 166.009 and 166.010, with the same crosshair dial.

Are there differences between these two case references?

 

1 - Gent's Watch
6 - Self-winding center second
6 - Water-resistant Calendar
Differentiation of various models: The only difference I can find on the Omega website shows that the 009 has the 565, and the 010 has the 562. I am seeing examples of the 009 with 562s with other searches.
010 - Cal. 562
009 - Cal. 565 quick set date

Thank you!

 

I’d say redial as well. Doesn’t look very crisp and the thickness of the crosshair seems variable.
