Original early Rolex silver wristwatch dating from the first quarter of the 20th century, representing the transitional period from pocket watches to wristwatches. The watch is fitted with an original Rolex manual-winding movement with 15 jewels, finished with silver perlage. Movement is correct for the period and runs well. The original sterling silver case (0.925) is fully hallmarked and signed Rolex / W&D / 925 / U / GS, confirming production by Wilsdorf & Davis, Rolex’s founding company. Case proportions and construction are consistent with early Rolex wristwatches. The watch retains its original two-tone dial in very well-preserved condition, with clear printing and no restorations observed. Original blued steel hands are present and correct for the period.
