About this entry

67% of key specs known. Missing: lug width, case material, hardening, AR coating, bracelet offered.

Sold as "Hiro 3D Lume Automatic" (listing "Hiro 3D index automatic"), as a watch head: "Bracelet / Strap: Sold separately", so no strap or bracelet is recorded. Brand spec list (each colour's page): "SII NH35 with 24 jewels Automatic", movement Japanese; 50mm case, 56mm lug to lug, 15mm thick (not said whether with the crystal); "K1 hardened mineral crystal"; screw-down crown; 200m; unidirectional rotating bezel (60-minute scale from the photos); exhibition case back; "3D green Superluminova hour indicators"; weight 5.6 oz (recorded as 159g, not said what was weighed, though the watch is sold without a strap). Lug width and case material aren't stated. The photos show no date window, so the NH35's date is recorded as not shown. The blue page's code is printed "A209BLU." (and its URL ends "a209blu..htm"); the trailing dot is left out of the reference. On 2026-11-01 grey was in stock on sale at $99 (Our Price $150); red and blue were $150 and marked sold out.
