Help with identifying my vintage Omega

Hi! Anyone recognize this Omega?

I´ve just gotten this watch as a graduation gift and I know little about it, perhaps that it is from the 60s or 70s?
It´s automatic, keeps perfect time. No hallmarks. I have not opened the case back. The case is 25mm wide.
It weighs 67 grams
Total lenght is 20 cm

I´m interested in the model and dating if possible. I realize it would be great with a pic of the movement but then I would need an expert to open it.

Thanks alot.

Quite possibly a men's De Ville from that era, as the hands seem to match. Dial has been redone. As @JimInOz mentions, more information is good 😀
(It's always a good idea to take the watch to a specialist who can open it up for you to check.)

Thanks, I will find a specialist and open it soon enough 😀 I don´t know what else information I have about it, is there any more photos you want?

Just a pic of the inside of the caseback and a clear one of the movement.

I'd also like to see clear close-ups of the inside of the clasp.

I suspect it houses an Omega Caliber 620.

Agree about the redial, but I reckon it's a woman's watch at 25x25mm.

Disagree. It's a men's dress watch for sure.

Bracelet is way too wide (18mm to 20mm) to be a ladies' model.

You may be right, but I thought 25mm square would be too small for a men's watch, even in the mid 1960s.

I'll vote for "uni-sex" then.

The JFK watch was even smaller than that one.

Very nice photos! @JimInOz's reckoning there was a Cal 620 in there was spot on. From the 22 million serial number, this would indicate the watch was made in 1965.

I have a feeling based on that caseback number it is a lady's watch...I will wait for @JimInOz's and @gatorcpa's expertise on this.

Great gift from your fellow friends!

You may be using a chart like this one:

http://www.old-omegas.com/omrefcod.html

Unfortunately, I think this case reference number, 833.529 or 833.0529, represents a case made for a specific market and doesn't conform to the normal conventions. The "8" does refer to a ladies watch and the first "3" means manual-wind. However, the second "3" is supposed to represent a chronometer grade movement, which this cal. 620 clearly is not.

However, this 1967 catalog picture shows a similar watch (in 9K gold), which is shown with a few other men's watches.

I guess they called this the "Slim" line in the UK.

The specialist could service and clean it for about 240$, sounds good right. I live in Sweden and they are certified resellers of Omega and other high end watches.

Thanks for all your information!

I believe the case reference is actually 055BB8061 - 18CT. YEL. GOLD CASE CAL. 620

CALIBRE: 620

DIAMETER: 25.50 mm - it's actually square even though they say diameter. Crystal dimensions are 22 X 22 mm.
