The Rolex Datejust is without a doubt one of the most distinguished watches in the Rolex Collection. Rolex is considered a pioneer of numerous innovations. Back in 1945, the Geneva watch manufacturer launched the Oyster Perpetual Datejust. As simple as sounds, the quick changing date was a milestone in the development of watches. The Datejust was the first self-winding, waterproof, chronometer wristwatch to display the date in a small window at the 3 o’clock position on the dial. The Rolex 279173 is paired with a stainless steel and 18k yellow gold Rolex Jubilee bracelet. Fixed - fluted 18k yellow gold bezel.

Screw down crown. Case size: 28 mm. Round case shape. Water resistant at 100 meters / 330 feet. Functions: date, hour, minute, second. This watch is also known as Rolex 279173, 279173
