About this entry
79% of key specs known. Missing: weight, hardening, end links, link attachment.
The brand writes this code "SN0053" in its listings (SN0053-G, SN0053-G2) but files both under its SN053 category, which also holds the unrelated SN053 dress watch (sn053-pt5000, sn053-sw200). SN0053-G (gradient brown or blue sunray dial with gilt or steel hands) and SN0053-G2 (textured blue, purple or gray gradient dials) give identical specs and are $288 each: "NH35", 316L, 39mm, 48.5mm lug-to-lug, 12.25mm (not stated whether that includes the crystal), 20mm lugs, sapphire with AR coating (side not stated), "GS hands" with lume, "BGW-X1 Blue Lume Light" on hands and markers, screw-down crown with 3D hexagon logo, brushed screw-down caseback, solid 316L five-link jubilee bracelet 20mm tapering to 16mm with the "New Fly Adjustable Clasp", 100m; weight not stated; no custom logo. The listings call it a diver, but no bezel is described and photos show a plain fixed bezel with no timing scale, so it is styled as a sports watch here. All dials show a date at 3. Both listings were in stock on 2026-10-25.
