About this entry
79% of key specs known. Missing: hardening, end links, link attachment, clasp micro-adjust.
Merges the SN0113-G and the "New SN0113-G1 Version", which quote the same specs except the clasp. Brand specs: 316L, 38mm, 47mm lug-to-lug, 13mm (not stated whether it includes the crystal), 20mm lugs, "bubble convex" sapphire with AR coating (side not stated), polished steel bezel (fixed, from photos), matte black dial, lumed arrow hands, "retro" SLN C3 green lume on hands and markers with BGW-9 blue on the 3/6/9/12 numerals, screw-down crown with hexagon logo, brushed screw-down caseback, 100m, about 132g (not stated what was weighed). Bracelet: three-link solid 316L, 20mm tapering to 18mm (oyster style in the photos). The G has a butterfly clasp ($238); the G1 has the Fly Adjustable BK1642 folding clasp with safety ($258, on-the-fly), so the clasp is recorded per variant in `configuration`. The NH35 has a date but the photos show no date window, so complications are time only. inspired_by is read from the design (38mm, 3-6-9-12 numerals with triangle markers, arrow hands, and the brand's "Classic 1957 Retro" naming); the brand does not name it. Both listings are simple products, but each carries a leftover "Dial Design" attribute ("Dial A with ST3621 Movement", "Dial B with NH35 Movement") that offers no choice; the NH35 named in the spec text is recorded. The store files both listings under its SN030 and SN0107 categories as well as SN0113; the watch is unrelated to the SN030 pilot. The SN0113-G listing links to an AliExpress listing that could not be checked (bot check). Both listings showed "Out of stock" on 2026-10-25, so production status is unknown.
