It's difficult to envision 60's racing culture without any sort of accessories to boot. It's definitely difficult to see it without the tool watches at that time. Heuer was perhaps at the forefront of all of it with it's many models of Carrera, Autavia and even the Monza and Camaro. 
 
But whenever theres a top of the line, there also an economy line. And this is where this Hamilton reference 7723 comes in to place. One of the reason why these things are so popular is because they're the affordable version of the Heuer's Carrera. They are quickly becoming a good enough alternative without breaking the bank too much. Heuer made these Hamilton chronographs towards the end of the 60's. It's sporty looks is enough to win every other collector out there. 
 
These vintage Hamilton chronographs are becoming so popular that Hamilton created a homage piece which was revealed to the world as the Intramatic 68 back in 2017 in Baselworld. You've probably heard of the term "Poor Man's Heuer" if you've been in the loop in the vintage watch world.. These are chronographs that were made to resemble the Heuer's I mentioned above but as an affordable alternative. The term "Poor Man's Heuer" gets thrown around these days on every watch that does resemble a Carrera - but generally speaking they don't necessarily belong in that category.
 
The watch is in excellent condition as you can see from the photos. The watch uses the Valjoux 7730 movement, comes with its original signed crown and hands. The lume and dial is in tact with no visible flaws. The case is unpolished.
