About this entry

58% of key specs known. Missing: lug-to-lug, case material, hardening, lume, bracelet links, end links, link attachment, clasp micro-adjust.

Aragon lists this case and movement under two names and product codes, both in the listing "ARAGON Divemaster Automatic NH36": "DM 42 NH36" (A198BLU) on a stainless steel bracelet, and "DM NH36 42mm" (A199BLK, A199BLU, A199WHT) on a silicone strap. The A198 dial has an Arabic 12 and its bezel is numbered every five minutes, while the A199 dials have no numeral and bezels numbered every ten minutes (from the photos), so the two blues are separate variants. Brand spec list (each page): "SII NH36 Date/Day with 24 jewels", movement from Japan; 42mm case, 14mm thick (not said whether with the crystal); sapphire crystal with anti-reflective coating (side not stated); screw-down crown; ceramic bezel, "Superluminova index glow blue on bezel" (the white page says "on bezel & dial"); 200m; exhibition case back. A198: stainless steel bracelet, 8.5" long and 20mm wide, "Fliplock push button solid deployant clasp", weight 6.8 oz (recorded as 193g on the bracelet). A199: silicone strap, 8.5" long and 20mm wide, 20mm stainless steel buckle, weight 4.0 oz (recorded as 113g on the strap). Neither page says what was weighed; the figures are filed by the build each page sells. Lug width is taken from the bracelet and strap width. Lug to lug and case material aren't stated. On 2026-11-01 A198BLU was $260 and the A199 colours $200 (white $230), all in stock; the A199 pages also offer a 20mm 7-link bracelet for $40 more.
