Seiko NH35 version of the Addiesdive H5, a large shrouded diver that the store calls "Tuna", after Seiko's Tuna, with round lume plots, a triangle at 12, a date at 3 and a ceramic bezel insert; the shroud is held by hex screws (product photos). The listings are titled "MY-H5", the store's earlier code style, while its accessory listings ("Accessories for H5", "The Steel Bezel of ADDIESDIVE H5C, H5") use "H5", recorded as the model code; the NH35 options carry internal SKUs JGK448-x. The main listing offers each colour with an NH35 or an "8215" movement; the Miyota 8215 options carry SKUs AD2522-x and are recorded as a separate model (see ad2522). The H5C "Emperor Tuna" is a different listing. Brand specs from the main listing ("Model: H5"): "Japan NH35/8215 automatic", 316L case and caseback, "120 click unidirect rotational ceramic bezel", sapphire crystal with AR coating (side not stated), "Swiss C3 green super luminous", screw-down crown, screwback case, 300m, "Case diameter: 47.5mm (without crown)", "Case length: 44.7mm (lug to lug)", 15mm, 22mm lugs. The U.S. listing repeats 47.5mm, 15mm, 22mm and 300m and adds "316 stainless steel", sapphire "with anti-glare blue coating", a ceramic unidirectional bezel, a folding clasp with safety, "Watch weight: 198g" and "Watch length: 260mm". The dimension graphics disagree with the text: the main listing's graphic marks 44mm across the case and 47.5mm from lug tip to lug tip (the reverse of the text), with 15mm, 22mm, 240mm and 198g on the bracelet; the U.S. listing's older graphic marks 47.5mm lug to lug, 22mm, 240mm and "Net weight 215g". The spec-text values are recorded (diameter 47.5mm, lug-to-lug 44.7mm, 198g); the 198g is recorded as on the bracelet because the graphic shows it with the bracelet. Whether the 15mm includes the crystal is not stated. Lume: the text names only C3, but the brand's lume photos show the dial markers and hands glowing green and the bezel numerals and scale glowing blue, so bezel lume is from the photos only. Also from the photos only: the 60-minute bezel scale, the solid caseback engraved "Automatic movement NH35 Dive 300M by Addies", the three-link bracelet and the fold-over clasp with safety lock and spring-bar micro-adjust holes; end links and link attachment are not stated. Dial prints differ between photos: the current product shots read "Automatic 300m", the lume photo and the U.S. listing's main photo add "Deepseahunter", and older U.S.-listing photos read "Marinemaster Professional 300m". All three colours $149 from China (no crossed-out price, all in stock on 2026-10-21); a U.S.-warehouse listing (ships to US addresses only, SKU US-JGK448) sells the black dial at $159.99, recorded as a separate configuration. Same 15mm / 22mm / 300m figures as the smaller 41mm AD2090, AD2098 and AD2509 tunas, which have their own cases. No review was found.
