Can anyone tell me the model and approximate age of this watch? It was my great uncle's watch and I do not have any information on the watch.

Thank you for the reply. I had seen that link but my watch does not have that "T" symbol above the Swiss above the switch. Not sure if that makes a difference in the identification.

 

T stands for tritium. It’s the luminous material used for the markers. I don’t think anybody fully understands why some dials have the T and others don’t. Certainly very early watches from the start of the sixties still used radium and had no T. Also it’s been hypothesized that some regions didn’t require the T whilst others did. Either way I’d say that your watch is a 7725.

Edit to add a link for a no T 7725

That would explain why there are no luminous marker on my watch hands. Is there a site that would have a manual or additional information on this model? I would like to know the operation of the watch and also have it cleaned and possibly serviced and have a more appropriate vintage style band for it.

 

Pretty sure the hands do have luminous paint, just it’s too old to function well.

 

I see that now when I zoom in. Would it be better to leave the watch in the current condition or have it restored?

 

You want to keep it or sell it ?

 

Keep it.

 

Then get the movement serviced. I don’t see a need to do anything else. You could even polish the scratches out of the crystal yourself if you’re careful, but don’t polish the plating off the case ! And I’d definitely ditch that bracelet.

 

Thank you for the help. I agree on the bracelet. I am just glad that I noticed my father wearing it around the farm and told him that he probably shouldn't wear it while feeding cattle. I asked him where he got the watch and he said it was my great uncle's watch that still worked so he put an old band on it that he had laying around and started wearing it. He had never heard of Heuer.

 

Yes it’s probably worth looking after.

To be clear it’s pretty much the least desirable chronograph they ever made, but Heuer is pretty well sought after. Just to give you a ballpark figure I think you’d be looking at close to $1000 as is. I think most of the value is in the movement if it’s a correct one signed MN.

 

Although the case looks 772x the crown seems to be a much older style and the pushers are mismatched. Both could be repairs after damage. My 7721 of 1969/70 has lumed hands & plots but no "T". If you get the bracelet off the reference (model number) will be between the lugs at "6" and the serial number at "12".

Service is a definite requirement if you are going to wear it, which you should. Operation? Wind it once a day, top button starts and stops the chronograph, bottom button resets (but only use this when it is stopped). There is a register of serial numbers of Heuers of this era, post or PM when you have it,

Nice

 

I will look for the model and serial number and let you know. Thanks for the info.
