Thanks. H.P.C. means high precision chronometer? Not all UG with the Cal 291 movement were marked that way. I actually scoured the internet and couldn't find one.
you have come to the right place ! read this all the way through and you will have the answer. Or skip to the end if you don't want to wait.

Thread 'Chronographs classified as Chronometres.' ·According to this 1950's ad, some chronographs were classified as chronometres.
Anyone ever seen one, does Sala list them?Moahunter ·
Thanks for the link; it sheds a whole new light on the meaning of those three letters, HPC. I wonder if the watches came out of UG with the inscription already on them, or if the inscription was created in Caracas?
The HPC research machine got going after your very specific question: "Are the rules for HPC dials different from the rules for chronometer dials?"
Someone asked another brilliant point: not all watches marked with an HPC dial have a movement certified as a chronometer.
I always thought HPC meant highly polished case.
