Shrouded diver that the store calls "Tuna Diver", after Seiko's Tuna, with wave-textured "enamel base" dials and a light-coloured ceramic bezel insert. Brand specs ("Model: AD2098"): "Japan NH35A Automatic Movement", 316L case, brushed and polished, solid 316L screw-down caseback, "Ceramic with BGW9 Lume at 12 o'clock" bezel insert, dual-domed sapphire crystal with "AR Blue" anti-reflective coating (side not stated), applied markers and sandblasted hands with BGW9 lume, 7mm screw-down crown, 300m, solid 316L steel bracelet with a fold-over clasp, "Bezel Diameter: 41mm", 44.5mm lug-to-lug, 15mm "including crystal and case back", 22mm lugs, 220mm total length, 208.5g. The brand gives only a bezel diameter, which is recorded as the diameter; its dimension graphic draws the 41mm across the shroud. The graphic shows the watch on its bracelet with 208.5g, so the weight is recorded as on the bracelet. The bezel's direction and clicks are not stated; the 60-minute scale is from the photos. The three-link bracelet and the safety lock and spring-bar micro-adjust holes in the clasp are from the photos; end links and link attachment are not stated. Sold from China at $139 for every colour (no crossed-out price) and from a U.S.-warehouse listing (ships to US addresses only) at $149.99, recorded as a separate configuration; on 2026-10-21 the U.S. listing had only White in stock. Shares the 41mm / 44.5mm / 15mm / 22mm / 300m figures with the AD2090, which has an aluminium bezel insert.
