A 42mm compressor-style diver with an Epson YN55 (recorded as the YN55A, as on the published SN0004 and SN006): an internal rotating bezel set by the upper crown at 2 and the winding crown at 4. Brand specs: 316L, 42mm without crown, 46.5mm lug-to-lug, about 12.4mm including crystal, 20mm lugs, sapphire with AR coating (side not stated), enamel black dial with applied 3D markers and silver arrow hands, BGW-9 blue lume, screw-down crown (not stated whether that includes the bezel crown), screw-down solid caseback, 200m, solid steel bracelet with "Fly Adjustable Clasp" (recorded as on-the-fly micro-adjust, as on the published SN0004 and SN006; clasp type, positions and range not stated). The brand notes its figures are hand-measured. The oyster-style 3-link bracelet is from photos. The listing is a single option with the black dial; its attribute tags also name "Sunray Blue" and "Sunray Salmon" dials and a with/without logo choice that cannot be ordered and are not shown, so only the black dial is recorded. Photos show a date window at 6. No weight is given. The listing showed "Out of stock" on 2026-10-25, so production status is unknown.
