The SN051 is sold as two listings in the same case, each with its own movement: the SN051-G with an NH35, recorded here, and the SN051-G2 with a YN55A (see sn051-yn55a). Brand specs (G): NH35, 316L, 39.5mm, 48mm lug-to-lug, 13.5mm (not stated whether including crystal), 21mm bracelet width, "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 with printed 3D time scale, curved hour and minute hands, "retro luminous effect" C3 green lume on hands and markers, screw-down crown with 3D "S" logo, screw-down caseback with pressed 3D shark logo (marked SUB-0051 and NH35A in the photos), 3-link solid 316L bracelet with folding safety clasp and hexagon logo, 200m, about 177g (not stated what was weighed). The G listing gives only the 39.5mm case; the 41mm bezel diameter recorded is from the G2 listing, which quotes the same 39.5mm, 48mm and 13.5mm case. The 60-minute bezel scale, the Arabic 3-6-9-12 numerals with script logo and the vintage-tinted lume are from photos. Inspired_by follows the listing's "SM300" name and the design (sandwich dial, ceramic-topped bezel, Arabic numerals); the brand does not name the Omega. Both dials come with or without the San Martin logo at the same price ($248). The NH35 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.
