Yacht-Master-style automatic (the title says "Yacht-Master 40mm"; the description calls it the "Neptune series") with a steel bezel carrying raised numerals, lumed dot and baton markers, a date at 3 under a cyclops and an oyster-style bracelet. Brand specs: "Movement manufacturer: Japan Seiko, Movement model: NH35A" (Seiko NH35A, recorded; the title, a "Japan Seiko NH35A" panel and the description's spec panel and parameter table agree), stainless steel case, 40mm, 13mm case thickness, 20mm band width, 10 bar, sapphire crystal, stainless steel band ("210cm", i.e. 210mm) with a "Bracelet Clasp", and a "Two-Way rotation" bezel ("two-way rotating outer ring" in the description). The description's spec panel (Japanese Seiko NH35A, sapphire crystal, stainless steel, 13mm, 150g, 100M/330FT) and parameter table (40mm, 13mm, 20mm, 210mm, 100M, "watch weight 150g", recorded as unspecified) agree. A "Luminous index" image shows the hands and markers glowing. The photos show a display caseback and a "double button butterfly clasp"; three-piece links are counted from the photos. AR coating and lug-to-lug are not stated. $139.99 for all colours on 2026-10-24, all sold out on 2026-10-25. No independent review was consulted.
