About this entry

93% of key specs known. Missing: hardening.

The SN049-G listing sells a 43mm military-style diver with a choice of Miyota 8315 at $278 (this file) or Miyota 8215 at $258 (sn049-8215), each with or without logo at the same price; it is only offered on a leather strap. Brand specs: "Miyota 8215/8315", 316L, 43mm, 51mm lug-to-lug, 13.5mm (not stated whether that includes the crystal), 22mm lugs, slightly domed sapphire with AR coating (side not stated), 120-click unidirectional stainless steel bezel with lumed 12 o'clock marker, black dial with printed indices and applied hexagon logo, broad arrow hands, BGW-9 blue lume on hands and markers, screw-down crown with 3D hexagon logo, brushed screw-down caseback, quick-release genuine leather strap 22mm tapering to 20mm with a solid 316L buckle, 200m, about 118g (not stated what was weighed; the watch is only sold on the strap). The brand calls the bezel a "chronograph" bezel; photos show a 60-minute scale. Photos show no date window, so complications are time only. Both movement options showed "Out of stock" on 2026-10-25, so production status is unknown.
