Asulab made at least 150 of those HPM prototypes, I really want to get one
Afaik they worked well so I don't know why Swatch gave up on it. Richemont tried it too, but made even fewer units.
In the meantime, Epson has pushed the technology to the extremes of accuracy with the 9RA2/5 and 9RB2 movements that I bet the Asulab team never even considered possible.
