"It is an early 1930s production Rolex Oyster Bubbleback 1st model with a silver sector dial. Normally, the Bubbleback models from the 1st model to the later NA models have two screw holes in the center part of the rotor, but this is a rare piece manufactured before the addition of those screw holes. This watch holds great historical value in Rolex's history. It features a 4-piece structure consisting of the bezel, middle case, case back, and movement holder in its early waterproof case design. It is equipped with the early type movement Caliber 520, which has the handling instructions engraved. This remarkable and precious item showcases the Art Deco design with a silver sector dial, capturing the essence of its era and exhibiting a splendid taste."
