Miyota 8215 version of the Addiesdive H5 (MY-H5; see 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. It is sold only as the "8215" option of the H5 listings, whose black 8215 option carries SKU AD2522-2 (US-warehouse SKU USTH-AD2522-2), so AD2522 is recorded as the model code; the blue and green 8215 options have no SKU. The listings' spec text is shared with the NH35 version and gives "Japan NH35/8215 automatic" (the 8215 is Miyota's caliber), 316L case and caseback ("316 stainless steel" in the U.S. listing), "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, and in the U.S. listing a folding clasp with safety and "Watch weight: 198g". The spec-text dimensions are recorded; the main listing's dimension graphic marks 44mm across the case and 47.5mm lug to lug instead (with 15mm, 22mm, 240mm and 198g on the bracelet). No weight is given separately for the 8215 version, so none is recorded. Whether the 15mm includes the crystal is not stated. From the photos, which are shared with the NH35 version (one black 8215 photo has a "Movement: 8215" inset): bezel lume glowing blue while the dial glows green, the 60-minute bezel scale, the solid screw-down caseback (engraved "NH35" in the NH35 photos; no 8215 caseback is shown), 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. Prices on 2026-10-21: $119 from China for all three colours (no crossed-out price; blue and green sold out), and $139.99 for the black dial from a U.S.-warehouse listing that ships to US addresses only, recorded as a separate configuration.
