About this entry

79% of key specs known. Missing: 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 is the steel SN030-G listing (its spec list says "Model: SN030-G2") with an Epson YN55A; the SN030-G-A3 sells the same sunray dials with an NH35 (sn030-nh35). Brand specs: 316L, sapphire with AR coating (side not stated), sunray green or blue dial, luminous hands, Super-LumiNova C3 green on hands and markers, screw-down crown with 3D hexagon logo, 316L screw-down caseback, 20mm 316L bracelet with female end links or leather strap, folding clasp with safety and hexagon logo, 200m, "about 143g/80g" (read as bracelet/strap). Not stated whether the 12mm includes the crystal; the other SN030 listings say it does. Bracelet style and link count are from the photos. $168 on the bracelet, $138 on leather. Photos show no date window, so complications are time only. Inspired_by is read from the design (Type A observation-watch dial); the brand does not name it. Every variation showed "Out of stock" on 2026-10-24, so production status is unknown.
