Everyday, water, active, adventure

It is the dive watch enthusiasts point to when someone asks for a real automatic diver under 500 euros. Unlike Seiko's equivalents it has a sapphire crystal, plus a screw down crown, 200m and an in house movement that hacks and hand winds. The 46.8mm lug to lug lets it wear like a smaller watch than 41.8mm suggests. The oxblood dial gives it character.

Sapphire, 200m and an in house automatic where rivals use Hardlex.

What owners say

WatchUSeek owners rate the watch head highly and often swap the tinny bracelet for a Strapcode or rubber strap. Alignment of the bezel and minute hand varies between units, and a few owners report the bezel dropping from 120 to 60 clicks after a year.
