The SN021-G listing (titled "36mm"; the brand gives a 36mm bezel and a 37mm case) sells this case with a PT5000 at $299 or a Sellita SW200 at $430, with an applied or printed hexagon logo, printed text or cursive text logo, or no logo, all at the same price. This file is the Sellita SW200 version; see sn021-pt5000 for the PT5000. The listing only says "SW200"; the current SW200-1 is assumed for the movement id and the grade is not stated. Brand specs: 316L, 37mm (36mm bezel), 45mm lug-to-lug, 11mm (not stated whether that includes the crystal), 20mm lugs, sapphire with AR coating (side not stated), polished steel bezel (recorded as fixed with no insert), black 3-6-9 dial, "curved carving craft" hands, BGW-9 blue lume on hands and markers, screw-down crown with hexagon logo, brushed screw-down caseback (a verified owner's review on the listing confirms a solid steel back), solid 316L bracelet, folding clasp with safety and 4 micro-adjust holes (recorded as tool micro-adjust), 100m, about 133g (not stated what was weighed). Bracelet style is from photos. The later SN021-G-B1, B2 and B3 listings use a top-hat sapphire and quote 11.3mm and 45.5mm or 45.9mm lug-to-lug, so they are kept as separate models (sn021-b1-*, sn021-b3-*). Inspired_by is read from the design (3-6-9 dial on a 36mm-class explorer case) and the listing title's "explorer"; the brand does not name the Rolex. The movement has a date but the photos show no date window, so complications are time only. Every variation showed "Out of stock" on 2026-10-24, so production status is unknown.
