| [[Reference:1505|1505]] || Auction estimates circa 1960–1980; the circa-1960 date conflicts with the case serial chart || Cal. 1570 in reviewed auction catalogues; no changeover established || Rolex’s 1980 catalogue describes the steel-and-gold model as the 1503 in steel and gold, with a “fancy dial.” Cambi labels a circa-1971 all-steel example; attribution unresolved. Auction catalogues show blue, silvered and champagne dials, varied bezel terminology, and 34–36 mm measurements

|-

| [[Reference:1506|1506]] || Individual records dated 1960–1967; production limits unknown || Cal. 1570 in two auction catalogues; one seller lists 1575, while its movement photo shows a 1570-marked bridge || 34 mm yellow-gold Date examples with patterned bezels and bracelets called Chine; an inner 1503 caseback stamp and a 1506/1503 catalogue entry remain unexplained

|-

| [[Reference:1507|1507]] || Auction estimates circa 1962–1975; production limits unknown || Auction catalogues label examples Cal. 1560 or 1570; exact fitment unverified || Yellow-gold Oyster Perpetual Date. The inside caseback of a Sotheby’s 1507 is stamped 1503; other catalogues use 1503/1507. Collector lists call the bezel tightly fluted, while auction terms vary. The linked page documents the case, dial and movement evidence
