The SN034 is a 37mm military-pilot case with a smooth fixed bezel, sold in steel with a Miyota 8215 (this file), a Ronda 6004 (sn034-ronda-6004) or a Ronda 715 (sn034-ronda-715), and in bronze with a Ronda 6004 (sn034-bronze-ronda-6004) or a YN55 (sn034-bronze-yn55a). This file merges two listings of the same case and movement: the SN034-G (textured "oil pressure fire pattern" black dial with Arabic numerals) and the later SN034-G-B1 (matte black dial with a triangle at 12, 3-6-9 numerals and a minute track). Brand specs: Miyota 8215, 316L, 37mm, 45mm lug-to-lug, 11.5mm on the SN034-G and 11.2mm on the SN034-G-B1 (within San Martin's hand-measuring, so treated as one case; neither says whether the crystal is included), 20mm lugs, sapphire with AR coating (side not stated), luminous hands, C3 green plus BGW-9 blue lume on hands and markers (the B1 listing names only BGW-9, and its night photo glows blue throughout), screw-down crown with 3D hexagon logo, 316L screw-down caseback, 316L bracelet with female end links or leather strap, 20mm, folding clasp with safety or pin buckle, 100m, "about 145g/80g" (read as on the bracelet and on the leather strap, the order the spec lists them). Bracelet style and link count, 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 date but photos show no date window, so complications are time only. Every variation of both listings showed "Out of stock" on 2026-10-25, so production status is unknown.
