About this entry

89% of key specs known. Missing: hardening, end links.

Current "New Upgraded" version of the SN0004 (brand writes both SN004 and SN0004). A1: black dial, retro yellow markers, C3 green lume, with or without logo; A2: black, blue or green dial, white markers, BGW9 blue lume, logo only. Both offered with Mercedes or pencil hands. Brand specs: 316L case 38mm, 46mm lug-to-lug, 13mm thick, 20mm lugs, sapphire with AR coating, 120-click unidirectional bezel with ceramic top ring and lumed 12 o'clock marker, screw-down crown and brushed screw-down caseback, 200m, about 146g (not stated what was weighed), solid 316L bracelet with female end links and the new "Fly Adjustable" folding clasp with safety (Long Island Watch calls it an on-the-fly ratcheting clasp; positions/range not stated). Long Island Watch (SN004-A, apparently the A1) adds the box-domed sapphire with AR on the underside, 146g, a three-link bracelet and a $249 US price (out of stock). Inspired_by follows the brand's "6200" naming; Two Broke Watch Snobs calls the SN004 a MilSub (ref. 5513) homage. Solid caseback and screw link pins are taken from the older SN004-G listing ("screw-down solid caseback", bracelet screws) and that review (screws, milled clasp, ~140g on the full bracelet), not restated on the A listing. Whether the end links are solid is not stated. The older SN004-G ($238, gilt hands, plain solid steel clasp) is still listed but out of stock. Both A listings showed "Out of stock" on 2026-10-20, so production status is unknown. Same case is sold with PT5000 or Sellita SW200 movements as the SN004-G-B (see sn0004-pt5000 and sn0004-sw200). Earlier NH35 batches, all $238 and out of stock on 2026-10-24, are kept as variants because the brand gives the same 38mm, 46mm, 13mm (including crystal) and 20mm case: the SN004-G ("with new 3-link bracelet", female end links, gilt hands, retro yellow-green lume, 140g); the SN004-G-V3 black dial (DLC gold pencil hands, retro lume, 140g; its leather dial uses a YN55A and is in sn0004-yn55a, like the whole V2); and the SN004-G-V4 (Mercedes hands) and SN004-G-V5 (pencil hands) in black, blue or green enamel with BGW9 lume, ceramic insert and about 143g. These older listings describe a "solid steel clasp" or "solid folding clasp" with no micro-adjust, so the on-the-fly clasp above applies to the A versions only. The V4 and V5 listings call the crystal only a "bubble effect crystal with AR coating", without naming the material. None of the SN0004 dials has a date window, so complications are set to time only.
