| [[Reference:1500|1500]] / [[Reference:1501|1501]] / [[Reference:1503|1503]] || Group examples circa 1962–1980; 1501 steel lots dated 1962–1977 and an 18K-gold lot circa 1973; 1503 includes a 1974 dealer-listed blue Shantung dial; production limits unknown || Cal. 1560/1570 auction labels; Rolex parts catalogues list date components under Cal. 1565/1575 || Oyster Perpetual Date. The 1500 has a documented smooth bezel; 1501 records include steel and an 18K-gold example with engine-turned bezel descriptions; 1503 catalogues and the Field Manual show gold cases and fluted bezels. Dealer listings add a blue Shantung dial, a plain-bezel outlier, and an outside-1503 / inside-1500 caseback pairing. The Christie’s caseback attributions remain unresolved; the linked pages explain the evidence.

| [[Reference:1504|1504]] || Individual records circa 1966–1972; limits unknown || Cal. 1570 in auction and dealer records || Gold Date with multiple yellow-gold Moreau examples; one white-gold specimen with a geometric bezel was sold twice. Inner caseback 1503 reported on separate 1504 examples; linked article separates these observations.

|-

| [[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
