About this entry

74% of key specs known. Missing: water resistance, hardening, end links, link attachment, clasp micro-adjust.

Every SN030 listing quotes the same 39mm (without crown), 49mm lug-to-lug, 12mm (including crystal on the listings that say), 20mm-lug case with a smooth fixed bezel; the SN030 is sold in steel (NH35, YN55A, Ronda quartz), titanium (NH35, YN55A), bronze (YN55A, PT5000, Sellita SW200) and Damascus steel (PT5000, Sellita SW200), each a separate file. This file combines three listings of the steel case with a Seiko (Time Module) NH35: the SN030-G-V2 (black Type A or Type B dial), the SN030-G-A3 (written "SN0030-G-A3" in its spec list; sunray blue or green Type A dial with printed logo, the NH35 version of the YN55A SN030-G) and the SN030-GW (white dial). Brand specs: 316L, sapphire with AR coating (side not stated), luminous hands, C3 green lume on hands and markers (Super-LumiNova C3 on the V2 and A3; "C3 Super Luminous" on the GW), screw-down crown (6mm on the GW), screw-down caseback, 20mm 316L bracelet or leather strap, folding clasp with safety and hexagon logo on the bracelet, pin buckle on the strap. Water resistance differs between listings: the V2 and GW say 200m, the A3 says 100m (10 bar), so it is left blank. Weights "about 143g/80g" (V2) and "about 145g/81g" (A3) are read as bracelet/strap. The bracelet style and link count are from the photos (three-piece brushed oyster-style links). Prices: $168 on the bracelet and $138 on leather (V2, A3), $165 for the GW on leather. Photos show no date window on any dial, so complications are time only. Inspired_by is read from the design (Type A and Type B observation-watch dials); the brand does not name it. Every listing showed "Out of stock" on 2026-10-24, so production status is unknown.
