Heuer Trackstar ?

Hi guys, I just signed here up as I was pointed this might be a great venue for some experts to chip in 😀

I recently stumbled upon this watch and it came in my possession. I think it was a part of a very old shrink set for finding out ones IQ.

It´s a Heuer Trackstop, 7 jewels. After some googling I think the model number is 603.202 but can´t be 100% sure.

Has anyone here any info about it or if it might be worth something ?
It was "serviced" about two years ago and it runs very well and keeps accurate time.

Any help would be great here.

Have a look at " onthedash " forum. They should know. Good luck !

Reference is 602.302 in this 1977 catalogue
