About this entry

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

Brand specs: 316L, 40mm, 48.5mm lug-to-lug, 12.7mm (not stated whether that includes the crystal), 18mm lugs, sapphire with AR coating (side not stated), "Multiple Color Unidirectional Bezel" (insert material and clicks not stated), applied indices, date at 3, sword hands, "Blue/Orange Lume" on hands and markers, screw-down crown with hexagon logo, screw-down solid caseback, 200m, "New fly-adjustable Extension Clasp" (recorded as on-the-fly; positions and range not stated). Weight not stated. The 60-minute bezel scale is from photos. The spec list says "Mesh Stainless Steel Bracelet / Rubber Strap", but the option is "Stainless Steel Bracelet" and the photos show a three-link bracelet (link count from photos), so mesh is not recorded. $278 on rubber, $318 on the bracelet, any colour; in stock on 2026-10-25. Kept apart from the SN0118-G, G1 and G2 (sn0118-nh35): same 40mm and NH35, but 18mm instead of 20mm lugs and 48.5mm instead of 47.8mm lug-to-lug, and the listing's "Comparison with SN0118-G" photos show broader bevelled lugs and a different case profile. Its case figures match the SN0118-JS chronograph (sn0118-sl4801).
