About this entry

60% of key specs known. Missing: lug-to-lug, case material, hardening, AR coating, lume, bracelet offered.

Sold as "DiveTank 48mm" (listing "DF DiveTank SII NH35 Automatic"), in Aragon's DF (Depth Fighter) series; the 48mm NE57 power-reserve DiveTank is a separate model (divetank-48mm-seiko-ne57.yaml). Brand spec list (each colour's page): "SII NH35 Day with 24 jewels automatic", movement from Japan; 48mm case, 17mm thick (not said whether with the crystal); "K1 hardened mineral" crystal; screw-down crown; silicone strap, 9.5" long and 24mm 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 6.5 oz (recorded as 184g, 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. Dial colours are taken from the codes and photos (MOP, TEA). Lug to lug, case material and lume aren't stated. On 2026-11-01 mother of pearl was in stock on sale at $189 (Our Price $260) and teal was $260 and marked sold out.
