Swiss. Gold-filled. The Rolex Reference 3487 "Oyster Recorda" is a rare and historically significant mid-century timepiece that bridges the gap between Rolex's utilitarian roots and its mid-century expansion. This model is housed in a gold-filled Oyster case, featuring the screw-down crown and caseback that revolutionized water resistance in the early 20th century. The dial is a functional design, featuring a crisp "railroad" minute track along the outer edge for precise timing and a central sweeping seconds hand. Adding to its technical appeal is the inner 24-hour military track. Recently serviced. The watch is presented on a canvas strap with a gold-plated buckle. No box or papers. Marked, "132321" and "3478", on caseback. 28mm. Swiss.

Correct oyster patent crown, but originally was likely gold-toned. Heavy wear to gold-filled surfaces of the case. The nickel finish has worn off most of the movement plates. Excellent original dial and lume. The watch was observed to be running at the time of cataloguing. It has not been tested for timekeeping accuracy and may require adjustment.
