Rolex Datejust 6903 Description
Reference 6903 is an early model designation for the 26mm Oyster Perpetual Lady-Datejust, produced during the 1970s. This reference is historically significant as it was among the first to be powered by the Rolex Caliber 2035. This high-performance automatic movement operated at a frequency of 28,800 vph and introduced the ‘quickset’ date complication to the Lady-Datejust line. The technical specification denotes a 26mm Oyster case constructed from solid 18k yellow gold with a classic fluted bezel (03 designation). The watch is fitted with a domed acrylic crystal. Its significance lies in its status as a direct precursor to the long-running Ref. 69178.
