Brand specs: Sea-Gull ST2130 automatic (28,800 vph), 316L steel, 40mm without crown, 48mm lug-to-lug, 11.8mm thick (the brand doesn't say whether that includes the crystal), sapphire with AR coating (side not stated) and a 2.5x date magnifier, 120-click unidirectional bezel with a ceramic insert and a lumed marker at 12, BGW9 lume on hands and markers, signed screw-down crown, screw-down caseback, low-slope rehaut. The bracelet is 20mm tapering to 16mm, so the 20mm lug width is taken from it (no lug width is listed), with an upgraded dual push-button clasp with 5 micro-adjust holes; the 3-link oyster style is read from the photos. Water resistance is not stated. The spec list still names "sunburst blue / enamel black" dials, but the listing sells black dials with a black or green ceramic bezel, both $149 and in stock on 2026-10-24. The store tags it SUBMARINER; the date with magnifier and ceramic bezel follow the Rolex Submariner Date. Weight is not stated.
