·Collectors know the Spirotechnique TAG Heuer 1000m watch, which you can read about here
TAG Heuer, or rather, Zodiac, also made this similar version, for Auricoste which was sold as a Spirotechnique
These are the only Heuer/ TAG Heuer collaborations that I've seen with Spirotechnique..until this popped up- Spiroquartz
It's a PVD version of the Heuer 1000- but that was never available in PVD. It also wasn't available as a TAG Heuer, which tells us that this partnership with Spirotechnique likely came before the 1000m diver.
A cool find and another piece of dive watch history!
