The Oyster Perpetual Datejust is the most iconic timepiece in the Rolex catalog. It is characterized by a jump date mechanism at the 3-hour marker, a waterproof case, and a self-winding movement. The Datejust collection includes many metal options, dial colors, bezel and bracelet types, and case sizes. One of the newest additions to the collection is the Datejust II, which offers a larger 41mm case size, a newer calibre 3136 movement, and a contemporary dial set with fully-lumed hour markers. The ref. 126333 is a Yellow Rolesor edition that pairs Oystersteel with yellow gold. This example is a very desirable variation of the larger Datejust for its versatile two-tone finish that is easy to dress up or down to suit any occasion.
