The SN084-G listing sells one NH35 diver with a gradient blue mother-of-pearl or black enamel dial, each with or without the San Martin logo at $230 (custom logos for the blue dial only). Brand specs: "Time Module NH35", "±15S/day" (recorded as the brand's regulation claim; positions not stated), 316L, 43mm without crown, 50mm lug-to-lug, about 14mm including crystal, 22mm lugs, sapphire with AR coating (side not stated) and a cyclops over the date, ceramic bezel with a lumed 12 o'clock marker (direction and clicks not stated), applied three-dimensional markers, BGW-9 blue lume, 8mm screw-in crown with 3D shark logo, screw-in caseback, solid three-link steel bracelet 22mm tapering to 18mm with a solid folding clasp (micro-adjust not stated), 600m with a helium valve at 9, 200g (not stated what was weighed). Inspired_by is read from the design (blue to black gradient dial, 600m with helium valve, Sub-style case and bezel); the brand does not name it. Every variation showed "Out of stock" on 2026-10-25, so production status is unknown.
