Check out the lugs, and caseback and chronometer written on the dial, seller has 6000+ feedback all positive dealing antiques but I've never seen one that looks anything like that.

 

That is either a case ref. 2984 with a cal. 501 movement (non-chronometre) or a case ref. 2989 with a cal. 505 chronometre movement but either way the dial to me looks refinished. This is the same case style as the Seamaster XVI Melbourne olympics watch but in stainless steel.

 

If it turns out to be a 2989 with the correct 505 chronometre movement, it's a great piece for someone with the correct original dial.

 

Interesting, I've never even heard of such a thing before, the caseback though looks so unlike most others, its almost like the current Seamaster Pro caseback

 

Bill Sohne had one up for sale in 2007:

 

That caseback style was used for a few years in the earlier seamaster models before they progressed to the smaller logo. Bill's watch is the non-chronometre version.

 

Is this a Cal. 501?

 

I would be wary of this one without a movement shot. I think it's far more likely to be the non-chronometer cal. 501 movement like Bill's example above.

Since I've never seen the Ref. 2989, I don't know if it even came with a steel case. It's not listed in the Omega Vintage Database.

D -- If the caption in AJTT mentions a steel case, would you let us know?

Thanks,

The JTT picture of the 2989 was one in a steel case. Gator's point is well taken but this may be a gamble worth taking - the absence of a movement shot would likely diminish the price the item will go for.

 

Caliber 501, up close and personal:



Per Omega, this one is actually a 19J chronometer with a 20 jewel replacement rotor. It's in a Constellation Ref. 2852-5.

I'd love to find the correct chronometer engraved one,

Not any more!

Edit - I was able to find an auction record for a very poorly redone Ref. 2989:

http://www.burchardgalleries.com/auctions/2006/aug2006/01images/l1091.htm

Per the description, the caseback would have both references on it.

 

You may be right about the price especially if someone mistakes that dial for an original one!

 

What is the diameter of the watch (without crown) as well as the diameter of the dial? Was wondering if the size is the same as the gold seamaster xvi watches.
