PRX Powermatic 80

An integrated-bracelet revival of the 1978 original. 40mm steel, waffle-textured dial, and the Powermatic 80 calibre running 80 hours off a full wind. The tapering bracelet is the reason people buy it twice.

Winding & Setting

Hand-wind an automatic 20–30 turns before first wear. Never adjust the date between 9pm and 3am — the date wheel is engaged and forcing it strips the mechanism. Always screw the crown back down before contact with water.

Water Resistance

The rating on the case back assumes fresh gaskets. Rinse with fresh water after sea or chlorinated water, and have gaskets pressure-tested every two years regardless of how the watch is worn.

Service & Storage

A mechanical movement typically needs periodic servicing. Store it away from speakers, laptops and magnetic clasps, and keep the box and any included documents.
