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

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.[/QUOT
Although the case looks 77xx 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 👍
