This is a Rolex Oyster Bubbleback from the 1930s, an exceptionally rare 1st model with an Art Deco design and a silver three-tone dial. It features an early four-piece waterproof case construction consisting of a bezel, middle case, case back, and movement holder. The piece is equipped with the historically significant self-winding Caliber 520 movement, engraved with operational instructions.
The dial combines silver, mirror circles, and matte white with a rail track design, paired with blue steel baton hands, exuding a compact elegance. The big crown, characteristic of early waterproof cases, adds to its vintage charm and showcases the aesthetics of its time.
Included is a VERTEX-made Jubilee bracelet (wrist size: 19.5 cm), making this a truly valuable collector's item.
