Microbrand
Prometheus Watch Company
prometheuswatch.comBased in Amadora near Lisbon, Prometheus built a cult following in the early microbrand era with its now-discontinued Ocean Diver series, prized for distinctive design and exceptional build quality. The brand uses 316L stainless steel, titanium, and CuSn8 bronze cases paired with dependable Asian movements from Miyota, Seiko Time Module (TMI), Seagull, Shanghai, and Hangzhou. Over the years it has released characterful divers and tool watches such as the faceted Trireme, the elegant Signatura, the vintage-inspired Sailfish, and today's high-water-resistance Jamanta line, earning coverage from outlets like Worn & Wound and aBlogtoWatch.
Worth knowing
Lineup is currently narrow and centered on the single Jamanta diver model, with several variants frequently sold out, and the brand relies on off-the-shelf Asian movements rather than in-house calibers.
