79% of key specs known. Missing: hardening, end links, link attachment, clasp micro-adjust.

Shrouded diver the store calls "Emperor Tuna", after Seiko's Tuna divers, with a grey sunburst dial, a blue-to-black gradient chapter ring, round lume plots, a triangle at 12, a date at 3 and a steel bezel insert with engraved numerals; the shroud is held by hex screws (product photos). The listings are titled "MY-H5C", the store's earlier code style, while the store's spare "The Steel Bezel of ADDIESDIVE H5C, H5" uses "H5C", recorded as the model code. One colourway (SKU JGMY-H5C-2; the variant name is descriptive, the store gives none). Brand specs (the main listing's text is in Chinese and matches the U.S. listing's English text): "Japan NH35 automatic, 41 hours of energy storage", 316L case and caseback, "120 clicks unidirect rotational stainless steel bezel", synthetic sapphire crystal with AR coating (side not stated), "BGW9 blue super luminous", screw-down crown, 300m, "Case diameter: 47.5mm (without crown)", "Case length: 44.7mm (lug to lug)", 15mm, 22mm lugs. The spare-bezel listing gives the steel insert as 38 x 31.6 x 1.2mm with BGW9 lume and says it fits the H5C and the H5. The dimension graphic agrees with the text (47.5mm drawn across the case, 15mm, 22mm) and adds a 220mm length and 203g with the watch on its bracelet; the weight is from the graphic only. Whether the 15mm includes the crystal is not stated. From the photos only: the 60-minute bezel scale, the three-link bracelet and the fold-over clasp; in the lume photo only the bezel's pip glows, along with the dial plots and hands. Caseback type, end links, link attachment and micro-adjust are not stated. Compared with the H5 (see h5): the same NH35 and the same 47.5mm / 44.7mm / 15mm / 22mm / 300m figures in the text, and the store's spare steel bezel fits both, but the H5 has a ceramic bezel insert, C3 lume and black, blue or green dials, and its listings quote 198g; it sells at $149 from China. The 41mm AD2090 (aluminium insert), AD2098 (ceramic insert, double-domed crystal) and AD2509 (steel insert, BGW9) tunas (see ad2090, ad2098, ad2509) share the NH35 and the 15mm / 22mm / 300m figures but have their own smaller cases (41mm, 44.5mm lug-to-lug, 203g to 208.5g on the bracelet). Sold from China worldwide at $139 (no crossed-out price) and from a U.S. warehouse listing (ships to US addresses only, SKU US-JGMY-H5C-2) at $149, recorded as a separate configuration; both in stock on 2026-10-21.
