Pre-owned Rolex Date 1501 with blue dial. The key factor that separates the Rolex Date ref. 1501 from the Datejust of the same era is its slightly smaller case. While the classic size of the men’s Rolex Datejust is 36mm, the case size of Rolex Date measures 34mm, similar to the Air-King and Oyster Perpetual models that Rolex was producing at that time. The dial also presents a Cyclops window above the date aperture for better clarity. An engine turned bezel, matching metal Oyster bracelet and screw-down crown complete the watch’s sleek look. Like other vintage Rolex watches, the reference 1501 Date has an acrylic crystal (plastic/plexiglass). Ref 1501 does not disappoint. Released in the 1970s, this vintage watch offers a classic design.
