About this entry

79% of key specs known. Missing: weight, hardening, end links, link attachment.

The SN0142-G (date window between 4 and 5, blue or orange lume) and SN0142-G-1 ("No Date Window Version", written "SN0142-G1" in its spec list; blue lume only) listings sell the same case and movement, $258 each, so they are one model. Brand specs (identical on both listings): YN55 (recorded as the Epson YN55A, as on the other San Martin YN55 models), 316L, 39.5mm, 48.5mm lug-to-lug, 12.9mm including crystal, 20mm lugs, sapphire with AR coating (side not stated), matt black dial with printed hexagon logo, unidirectional aluminium bezel, lumed hands, BGW-X1 blue or orange lume on hands and markers, screw-down crown at 4 with 3D hexagon logo, screw-down solid caseback, solid 316L bracelet 20mm tapering to 16mm, "New Fly Adjustable Clasp" (recorded as on-the-fly micro-adjust, as on the other San Martin files with this clasp; positions and range not stated), 200m. Bezel clicks and weight are not stated. The three-link oyster style, the push-button extension in the clasp and the lumed bezel triangle are from photos. The SN0142-G-1 listing's attribute list also names Orange Lume, but it has no options, its spec list says blue lume only and every photo shows white markers, so it is recorded as blue lume only. Because the same case and movement are sold with and without a date window, complications are left to the movement. All three options were in stock on 2026-10-25.
