About this entry

47% of key specs known. Missing: lug-to-lug, lug width, case material, hardening, AR coating, lume, bracelet links, end links, link attachment, clasp micro-adjust.

Sold as "Hydraumatic G9 NH35 44mm" (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): A477 black, A478 gold, A479 brown. Brand spec list (each page): "Japanese SII NH35 with date automatic", movement from Japan; 44mm 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" long and 26mm wide (the black pages give only the 26mm width); "20 ATM - 200 meters - 660 feet"; "Unidirectional rotating bezel, superluminova index glow green on bezel"; weight 7.2 oz (recorded as 204g, 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. All fifteen pages in stock on 2026-11-01: $230, mother of pearl and white $250; the three orange dials were on a Halloween sale at $199 (Our Price $230).
