About this entry

87% of key specs known. Missing: movement, hardening.

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-SY quartz listing. The brand says only "Swiss Ronda quartz movement" without naming the caliber, so the movement is recorded as quartz. Brand specs: 316L, 39mm excluding crown, 49mm including lugs, 12mm including crystal, 20mm lugs, sapphire with AR coating (side not stated), luminous hands, "C3 Super Luminous" green lume, 6mm screw-in crown, screw-in caseback, 20mm leather or nylon strap with stainless steel pin buckle, 200m, about 65g (not stated what was weighed). The listing names dial designs A to F in black or green, but only Dial B (Type B) and Dial C (black cross-hair dial with yellow seconds hand), each on brown leather or a green NATO strap, can be bought, all at $130. Some listing photos show a dial with a small-seconds subdial, which would need a different caliber and isn't among the purchasable options. Photos of the purchasable dials show no date window. No bracelet is offered. Inspired_by is read from the design; the brand does not name it. Every variation showed "Out of stock" on 2026-10-24, so production status is unknown.
