About this entry
60% of key specs known. Missing: lug-to-lug, case material, hardening, AR coating, lume, bracelet offered.
Sold as "DiveTank 40mm" (listing "DF DiveTank SII NH35 Automatic"), in Aragon's DF (Depth Fighter) series. Brand spec list (each colour's page): "SII NH35 Day with 24 jewels automatic", movement from Japan; 40mm case, 15.5mm thick (not said whether with the crystal); "K1 hardened mineral" crystal; screw-down crown; silicone strap, 8.5" long and 20mm wide (lug width taken from the strap width), 20mm buckle; "50 ATM - 500 meters - 1650 feet"; unidirectional rotating bezel; exhibition case back; helium release valve; weight 4.3 oz (recorded as 122g, not said what was weighed). The NH35 has no day display and the photos show only a date window at 3, so the caliber is recorded as named and "Day" is taken as a slip. Lug to lug, case material and lume aren't stated. On 2026-11-01 all five colours were in stock at an Our Price of $260; blue, teal and yellow were on sale at $169 and white at $189, red at $260.
