This was my late grandfathers chronometer. He was an aeronautical engineer during ww2. I suspect 1940’s? I bought my own as a link to him recently choosing the Omega aqua terra Worldtimer.

I thought it would be an idea to restore this one. Firstly can anyone tell me anything about it and any advice on restoring?

Thank you.

Hello and welcome,

Firstly what you have is a chronograph and not a chronometer. A chronograph has a timer/stopwatch function ( which yours has ) and a chronometer is a watch with a consistently high accuracy.

Anyway, what you have looks to be late 30's early 40's and judging from the relative size of the pushers I'd hazard a guess that it is a cal 33,3 ref CK2077

Can you show more pictures of the watch and case please? And also measure it across the diameter without the crown, I'd expect about 37mm? If it's more like 33mm then you will have a cal 28.9 ref CK 2076

Either way it should have a screw back steel case and these are highly collectable references.

edit: I'm not sure- the bezel looks different to both 2076/2077, so more pictures are a must and if you are able to safely open it pictures of the inside case back and movement would be extremely helpful

The dial condition is very poor, so what are you hoping to achieve with the restoration?

The dial probably originally looked something like this one (which also shows some aging):

Thank you for your response. Really insightful. I will get the additional details and pictures as soon as possible. That picture you sent looks like a close resemblance.

in restoring it, I was wondering about getting it serviced and also restoring the face to newer condition. Whether this is possible ( which I'm sure it is) but also whether I should. I believe my father would be happy.

I have actually just come back from there and interestingly, my mother then brought out her own fathers watch which is also an Omega. I took a photo which I have attached just in case you know anything about this also?

Hi,

Thanks again - The watch is 37mm across as you expected. Some additional photos:

Yes, that's indeed a CK 2077 with a cal 33.3, so well done there. As to the age I'd say you are certainly in the right ball park, however using the movement serial number and not the case back number will give you a better idea.

As to restoration for now I think it would be wise to first learn about this pretty rare watch and slowly decide in which direction you want to go.

I would look for a good original donor dial and store the old dial untouched.
So you will have a high value watch in wearable/readable condition and can always swap back.
Finding a good donor dial will be a tough call but is doable with patience and some bucks...

And you will have to find a good watchmaker who properly takes care of this heavily oxidised movement.

It's also missing a part, right Erich?

Thank you - Any advice you can give would be very helpful. I have been messaging Chris who has been very helpful re dials etc.. I would be open to looking for one and certainly it needs a full service. It has been fascinating looking into it.

Chris, there are more issues... 2 parts are missing and one spring is broken.
See photo below, I have marked the missing parts with + and the broken spring with a circle in red.

Donor dials and donor movements can be found on ebay if you are patient and lucky.
If you let us know your location OF members can recommend reliable watchmakers in your region.

I concur - Simon is one of the best available in UK

We have decided to look for an original donor dial and internal parts as you have suggested. Do you know where we might begin to start looking for a dial?

thank you

I'd first let a good WM take a look and let him source the parts, or if he doesn't have them then source them together. As for the dial.....well, that's another story, but Ebay is as good a starting point as anywhere, but don't be fooled by a seller's sales patter....."original dial'' doe not always mean what you may think it to mean. It's a sharkpool out there and especially so for rare and valuable parts....like a 33.3 dial

We will send to the individual you have suggested Chris to get the ball rolling and see where it takes us. Thank you. Very exciting!
