About this entry

87% of key specs known. Missing: weight, 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 bronze SN030-Q with an Epson YN55A; the bronze SN030-Q2 sells the same case with a PT5000 or SW200 (sn030-bronze-pt5000, sn030-bronze-sw200). Brand specs: "polished solid bronze" (alloy not stated), 39mm excluding crown, 49mm including lugs, 12mm including crystal, 20mm lugs, sapphire with AR coating (side not stated), black dial, bronze luminous hands, C3 green lume, screw-down crown with hexagonal logo, screw-down caseback, 20mm-to-18mm leather pilot strap with bronze pin buckle, 200m. The caseback looks steel in the photos but the brand doesn't say. Dial A (Type A) and Dial B (Type B), both $175. Photos show no date window, so complications are time only. Inspired_by is read from the design; the brand does not name it. Both variations showed "Out of stock" on 2026-10-24, so production status is unknown.
