Double Red
Sea-Dweller DRSD 1665 — Double Red
Two red lines – “Sea-Dweller” over “Submariner 2000” – above a white “2000 ft = 610 m”, with painted tritium plots on a matte black dial. Collectors split the dials into Marks by small differences in the red print and the coronet. Casebacks read “Patent Pending” on early watches and “Rolex Patent” from late 1971; the Rolex name runs straight across.
The valve patent (CH492246) was filed on 6 November 1967 and granted in June 1970. Cases up to the 2.9 million batch use casebacks stamped IV.67; a thicker case arrived in the first quarter of 1972 (I.72). Double Red production ran from about 1.7 to 5.1–5.2 million.
