Design & Style

The 35mm PRX Powermatic 80 retains the signature retro sports look (aesthetic inspired by the original 1978 PRX design) with a tonneau-shaped case and an integrated bracelet.
It includes the “waffle” or tapisserie pattern on many dials, giving texture and visual interest.
There are colour choices: deep classic tones (blue, black, green) and more delicate options like white mother-of-pearl, plus gold finish variants for those seeking a more dressy or bold style.
The smaller size (35 mm) is designed to wear more comfortably on slimmer wrists, while still keeping proportions balanced in the bezel, bracelet, hands, and indices.

Thanks to the Powermatic 80 movement and Nivachron anti-magnetic balance spring, you get good timekeeping and resistance to everyday magnetic fields.
With ~80 hours of reserve, you can take it off for a weekend and pick it up again without resetting.
Sapphire crystal ensures scratch resistance, and the anti-reflective coating improves visibility.
100m water resistance means it’s safe for daily activities, swimming, etc., though not for deep dive work.

Ideal for those who want Swiss automatic watch quality without a large wrist presence.
People seeking dressy/sporty versatility in one piece—good enough for business, casual, date night.
Buyers who prefer vintage style cues in a more modern, wear-able size.
Anyone who values function: long power reserve, solid build, reliable movement.

Pros:

Excellent balance of elegance and sportiness in a smaller size.
Strong value: the specs (80h reserve, sapphire, integrated bracelet) are impressive for its price range.
Versatile design with multiple dial/finish options.

Considerations:

The smaller size may feel “too small” for those used to large watches (40 mm+) or those who prefer bold wrist presence.
Gold/PVD finishes can show wear differently vs. plain steel.
While the bracelet is integrated and well-finished, sizing still matters—clasp adjustment and comfort will vary by wrist shape.
