About this entry
93% of key specs known. Missing: hardening.
The 36mm quartz SN0105; see sn0105-vh31 for the SN0105-G-XB, a near-identical 36mm case (46mm lug-to-lug, 10.5mm) with a Seiko VH31 and a centre-seconds dial, and sn0105-nh35 for the 38.5mm automatic. The brand writes "RONDA 6004" without a suffix; the 6004.B is Ronda's small-seconds version and matches the dial, so it is recorded. Brand specs: 316L, 36mm, 45.8mm lug-to-lug, 10mm (not stated whether that includes the crystal), 18mm lugs, K1 mineral glass with AR coating (side not stated), matte black dial with small seconds, curved snake-head luminous hands, SLN C3 green plus BGW-9 blue lume on hands and markers, push-pull crown with 3D hexagon logo, brushed screw-down caseback, one-piece nylon strap 18mm with a 316L buckle, 100m, about 55.5g (not stated what was weighed). Sold with or without logo at $119. The movement has a big date but photos show no date window, so complications are hours, minutes and small seconds; the solid caseback and fixed bezel are from photos. Both options showed "Out of stock" on 2026-10-25, so production status is unknown.
