About this entry
79% of key specs known. Missing: hardening, end links, link attachment, clasp micro-adjust.
Steel SN034 with Swiss quartz; see sn034-8215 for the other SN034 builds. The brand says "RONDA 6004" without a suffix; the 6004.B is Ronda's small-seconds version of that caliber and matches the dial, so it is recorded. Brand specs: 316L, 37mm, 45mm lug-to-lug, 10mm (not stated whether including crystal), 20mm lugs, sapphire with AR coating (side not stated), textured "oil pressure fire pattern" black dial with small seconds, curved snake-head luminous hands, C3 green plus BGW-9 blue lume on hands and markers, screw-down crown with 3D hexagon logo, 316L screw-down caseback, 20mm leather strap with 316L buckle, 100m, about 57g (read as on the leather strap, the only strap or bracelet the spec list names; the SN034-A-SY quotes 58g on leather). The listing also sells a steel bracelet ($138 against $118 on leather); its style, folding clasp, the solid caseback and the plain fixed bezel are from photos. Each option is sold with or without the logo at the same price. The movement has a big date but photos show no date window, so complications are hours, minutes and small seconds. Every variation showed "Out of stock" on 2026-10-25, so production status is unknown.
