This Rolex Submariner Date reference 1680 is the watch that brought a date to the line without softening its tool-watch character. It stands at the center of vintage Submariner collecting, a reference whose long run left behind the small shifts in dial and case details that enthusiasts still parse closely. Its automatic movement keeps the mechanics in the familiar Rolex idiom, while the date remains the feature that set it apart from the no-date Submariner beside it. In stainless steel, the case measures 40mm across and 13mm thick, a proportion that still feels compact for a watch built to go underwater. The black dial preserves the stark clarity that matters most on a Submariner. Few Rolex sports watches show the brand's evolution so clearly within a single reference, which is why the 1680 remains a natural point of entry for anyone serious about vintage Rolex.
