I recently picked up this waffle dial off eBay. What case reference should I be looking for?

The dial is 27mm in diameter and attached to a partial bumper movement (the part with the movement caliber is missing).

I assume it fits in a 2767 or 2577 - anyone know if there are the differences in dial diameter between these? Or if it may fit other references?

Thanks in advance for the help!

 

I have my near equivalent model 2627 case. The movement is a bumper automatic caliber 355, date at 6, 65 years old, and the case is new. I have no idea whether it is correct for the movement, or not. But I think it looks okay.

I also have a caliber 352 bumper automatic, about the same vintage as yours, different dial. This on came in a trashed gold filled case which I replaced with thesteel,one in the same style. Right off hand, I don’t recall the case style number.

The first looks correct to me. The latter looks like a 2577 (potentially one of the earlier case references).

 

Regarding my waffle dial, I have two very similar dials. One in a 2577/2520 and one in a 2767. I don’t know however whether the dials are slightly different sizes.. anyone know?

2767


2577/2520 (excuse the crystal scratches/cracks - in queue for my watchmaker)

 

The case you refer to as the latter one (the calendar model), is marked inside the case back as 2677. It is a new case. The other one is case model 2577. The dial is not original to the movement, and the movement is not original to the case. The 2577 case is one I have had in my stash of Omega bumper parts movements for 45 years, and it was an oldie when I acquired it.

 

Sorry, I had them backwards! The second one looks like a 2627. I’m not familiar with a 2677 reference.

Still curious about the right case for my dial..

 

My mistake. The Omega date at 6:00 case number is 2627, not 2677 as first stated. This is a new case.

 

Anyone with experience matching 2577/2767 cases and dials?

 

2577 will be ok.

 

Thread necromancy.
@seekingseaquest do you still have this dial and hands?

 

Unfortunately not

 

Shucks

 

Thread necromancy again, does anyone know what difference there is between the 2577 and 2767 case?

Edit: AAH me talking in my sleep, the difference is of course the 2577 has a screwed down caseback and the 2767 snap back. This I knew already

 

The 2767 (to the right) seems to have a slimmer bezel.



This observation also holds compared to an older 2577 with slimmer lugs (ignore the floating second hand lol)

 

Yes the 2767 was introduced just before the jump to the full rotor models like the 2846 and as you say has the snap on back seen later. It can be seen as a transition piece. There is deffo variation in the lug and bezel thickness of 2577 models, they were in production for 7-8 years so it's understandable.

 

Thanks I did not know the difference in bezel also
