Sold as "Hydraumatic G9 NH35 50mm" (listing "ARAGON Hydraumatic G9 NH35 Automatic"). Each colour is its own product page; the code prefix gives the IP colour of the bracelet (and, in the photos, the case): A472 black, A473 gold, A474 brown. Brand spec list (each page): "Japanese SII NH35 with date automatic", movement from Japan; 50mm case, 16mm thick (not said whether with the crystal); "K-1 crystal"; screw-down crown; stainless steel bracelet with the IP colour, "spring-assisted expandable cuff-style bracelet", 8-3/4" long and 28mm wide; "20 ATM - 200 meters - 660 feet"; "Unidirectional rotating bezel, superluminova index glow green on bezel"; weight 8.4 oz (recorded as 238g, not said what was weighed); "Limited production 20 units per color and size execution", recorded as limited_to 20 on each variant. Dial colours as the pages name them (sunray aqua, lime and orange, platinum mother of pearl, and a white Superluminova lume dial that glows blue). The bracelet is a cuff joined to the case by springs, so no lug width is recorded. Lug to lug, case material and case back aren't stated. Twelve colour pages (no gold mother of pearl or orange, no brown orange); all in stock on 2026-11-01: $230, mother of pearl and white $250; the black orange dial was on a Halloween sale at $199 (Our Price $230).
