Prx Powermatic 80 Watch

the prx 40 205 may be slim, but it's a real powerhouse thanks to the powermatic 80 and the new automatic valjoux chronograph movements. The powermatic 80 movement offers a power reserve of up to 80 hours, which means you can take your watch off friday evening and put it back on monday morning, and it is still working with no need to reset or wind. The automatic a05 valjoux version offers a 60 hours of power reserve. It's a detail for those who like their free time to be truly free.
