Need help with this Omega rerefence

Team,

Got this watch and one of the reasons, besides the extreme low cost, was that it looks very "funky" and is very comfortable on the wrist.

I would love to receive some advise from the experts.

It's, for sure, a good example of the crazy 70's creativity:

1) The case back does not open, it just give access to the bracelet!
2) To get access to the movement, one needs to unscrew the crown and, using a proper tool, to remove the crystal!
3) As some Omega movements of this time, the date change by "pumping" the crown.

Enough said, I saw here that the reference of this watch is 166.081, but here is my question:

Searching the Omega vintage database, for this reference, I got this watch, that looks similar but is not the same (at least on the dial):

From Omega Vintage database I got:

Dimensions: Ø39 mm

Reference: ST 166.0081
International collection: 1969 - 1975
Movement: Type: Automatic (mechanical); Caliber number: 565; Created in 1965
24 jewels
With central sweep-second hand
Functions: Date
Case: Stainless steel
Case back: Unishell (case opening on dial side)
Dial: Different types of dials available, with luminous "stick" hands
Crystal: Armoured glass
Bracelet: Stainless steel (integrated)
Water resistance: 30 meters

My question is if the reference is correct our if there is another reference?

As a side note, using this "funky" dial one can only be sure about the time at every quarter hour.

Thanks in advance,

Nilo

Coincidentally, mrsnak just acquired . . .

. . . the very same reference, Nilo, which he said was produced in '69 (if memory serves correctly). Let's see if I can contact him this last working day of the year to provide some assistance . . .

Thank you ...

Art, No rush. After all this watch was promoted to the status of "eternal keeper" because my wife loved the retro style. Have a wonderful 2012. Nilo

mrsnak had a few comments . . .

. . . to share, Nilo. First, you were fortunate to get one on a bracelet because the watch "requires a special screw-down adapter for the link ends." Second, you don't need the dedicated Omega dial extractor . . . just be judicious when applying pressure....

Thanks Art and Mrsnak

I'm lucky enough that my watchmaker has the proper Omega tool. No issues there. Just a little weird. Cheers, Nilo

You did find the correct reference number...

By: mrsnak : January 1st, 2012-17:05

...I went through a similar discovery process. My watchmaker informed me that the Omega crystal removal tool for this model for this has only 4 prongs, as opposed to the usual 16, but that the regular one works fine with proper tension. He used it to get ...

Thank you. The great thing about Omega watches is ...

That is very simple, in many cases, to source parts. In this case my watchmaker replaced the crystal with a NOS one. Cheers, Nilo

Your describing the quick set of the 565 !,,

Hi Congrats on a classic 70s Omega with a killer 565 movement! Looks like you found the correct reference . Happy new year! Bill Sohne

Thank you Bill ...

Do you have a better way to describe this quick set process? Cheers, Nilo Note: There was some issue with the forum that prevented my response to show. I believe that is fixed. This message has been edited by nilomis on 2012-01-02 04:08:27

Unless I am missing something...

By: mrsnak : January 2nd, 2012-09:39

...our watches do not have a 'quickset' date function. The fastest way to advance the date is to turn the minute hand to about the 3AM position, then back to about the 9PM, then back to the 3AM, repeating until you arrive at the date you want.

hmm--- the 565 dos have quick set... Mr. Snak.

By: Bill Sohne : January 2nd, 2012-09:48

Hi Did your watchmaker confirm you have a 565 caliber movement inside ? The 565 has a quick set by pulling the crown out to the second position and then push it back in to advance the date... its a "pull n' push " action to advance the date. Good Hunting ...

Here is my "pump" explanation using a better English

By: nilomis : January 2nd, 2012-09:52

Thanks Bill. Nilo

Yes, definitely a 565...

By: mrsnak : January 2nd, 2012-18:32

...I also own more than a few Omegas with the push-pull date advancement, so was surprised to hear this. We had the movement exposed and all appeared well inside. Will have to revisit this...

It's a 565 ...

By: nilomis : January 2nd, 2012-09:50

And you can quick set using the "pump" of the crown. Image from the Internet Old-Omegas. It's clumsy but works. Cheers, Nilo...

Thanks nilomis and Bill

Not thrilled to learn that my Geneve probably has a damaged quickset part, but good to know it's how that particular movement should function correctly. Nice to post that chart for everyone to see. BTW- Those date quicksets are awkward enough, but when yo...

über funky! :)

By: blomman Mr Blue : January 2nd, 2012-04:28

Very nice - looks super funky! Congrats, Nilo! Sorry I have no info on this one... Best Blomman

You are correct ...

By: nilomis : January 2nd, 2012-04:47

But even with all this "funkiness" it dresses very well and is a pleasure to wear, even with the square (39mm) case. Cheers, Nilo
