The earliest 6610 dials carry a red-printed "50m=165ft" depth rating beneath the OCC line. Phillips Geneva 8 lot 95 (case 113,xxx) and Phillips Watch Auction One lot 167 anchor the variant; Antiquorum lot 368-493 documents another red-depth example. Red-depth dials concentrate in the 113,xxx serial cluster — first-year 1955 production. The red-depth signature is the cleanest dating anchor for an unrestored 6610. Hammer prices for red-depth examples cluster CHF 30,000+ at the lower end and HK$ 302,000 at the upper end (Phillips Hong Kong XV lot 1055).
