Caseback: Screw-down, 3D-stamped back (featuring a diver’s helmet / anchor motif) for water resistance and aesthetic detail. Crown: Screw-down signed crown (improves water-resistance / diver safety) Notes & What to Expect The “Mark III / Oceanfarer” version of the Odyssea is thinner and slightly smaller than older versions (which were ~ 41 mm and thicker), making it more wearable for everyday use while retaining dive-watch capabilities. The Miyota 9039 movement is a “no-date” automatic movement — meaning the watch has a cleaner dial (no clutter), but no date complication. The bezel uses a sapphire insert — a premium choice vs. common aluminum or steel — and the lume (BGW9 / C3) is strong for nighttime visibility. “Fumé / smoked-green” dial variant: green dial that darkens toward the edges, giving a vintage-inspired diver vibe. Many reviewers praise this variant for its subtlety — the sunburst/gradient gives the watch a more unique, less common look compared to black or blue.
