About this entry

47% of key specs known. Missing: lug-to-lug, thickness, weight, case material, hardening, crown, lume, bracelet offered.

The Poseidon line has an automatic model and a hand-wound chronograph (Poseidon Mechanical Chronograph); both listings share one spec list naming "Seiko/TMI NH36 or Seagull ST1901", so this automatic is recorded with the NH36. 43mm case, double-domed sapphire with AR coating, WR 100, silicone strap; all 22mm straps fit. Case material not stated. The brand's store is bilingual and lists the watch twice, as a Polish and an English product at the same price; both pages are listed as stores and prices cite the English one.
