About this entry

79% of key specs known. Missing: weight, bracelet links, end links, clasp micro-adjust.

Second-generation Marinor (the brand's image files are named "MARINOR_GEN_II"), a 1950s-style diver in hardened steel (1,200 HV; steel grade not stated on these pages) with a Miyota 9039 (no date). Brand specs: Ø39mm, 46mm lug-to-lug, 10.6mm case and 12.2mm with the boxed sapphire (AR coated, side not stated), 250m, screw-down crown and caseback, 120-click rotating bezel (the standard colourways call it a "diving bezel"; only the Rainbow pages state unidirectional and countdown). Bezel inserts differ: curved sapphire on the standard colourways, domed sapphire on the Rainbow (3301-A) and a steel "Retro-Scale" insert on the Rainbow White (3301-B). The diver bracelet has screwed links, quick release and a micro-adjustment system whose type is not described (a screwdriver is included with Rainbow bracelets). Each Rainbow reference is listed twice: on the bracelet at USD 650 and on an FKM tropical strap at USD 600. Atlantic and Caribbean Blue listings date from 2023 but now carry the Gen II specs. Replaces the 2023 Marinor (marinor-gen-i: 47mm lug-to-lug, 12.9mm, 300m). On 2026-10-25 the four standard colourways were in stock and both Rainbows sold out. Clasp type, lume on the bezel and weight not stated.
