The SN051 is sold as two listings in the same case, each with its own movement: the SN051-G with an NH35 (see sn051-nh35) and the SN051-G2 with a YN55A, recorded here. Brand specs (G2): 316L, 39.5mm case with a 41mm bezel (the larger figure is recorded), 48mm lug-to-lug, 13.5mm (not stated whether including crystal), 21mm lugs, "bubble convex" sapphire with AR coating (side not stated), 120-click unidirectional bezel with ceramic top ring and luminous 12 o'clock marker, matte black or matte blue sandwich dial, lumed hands, full BGW-9 ice-blue lume on hands and markers, screw-down crown with 3D "S" logo, screw-down caseback with pressed 3D shark logo, 3-link solid 316L bracelet with folding safety clasp and hexagon logo, 200m, about 175g (not stated what was weighed). The 60-minute bezel scale and baton indices are from photos. Inspired_by follows the listing's "SM300" name and the design (sandwich dial, ceramic-topped bezel); the brand does not name the Omega. Both dials come with or without the San Martin logo at the same price ($248). The YN55A is a date caliber, but no SN051 dial in the photos shows a date window, so complications are time only. Every option showed "Out of stock" on 2026-10-25, so production status is unknown.
