Sea-Dweller DRSD 1665 — Double Red · Double Red Mark 3
Undated
Red lines laid out like Mark 2, but the “D” of Sea-Dweller now sits over the “R” of Submariner; thinner font with an open 6 in the depth rating, heavier depth-rating print, and a longer, slimmer coronet with a flatter base. Inside casebacks carry the full serial.
