WHAT A DIFFERENCE A DAY MAKES
In the earliest models of the Datejust, the date would begin to change some hours before its midnight rendezvous. In 1955, the date-change mechanism became instantaneous, and the date aperture was enhanced with a Cyclops lens enabling magnification of the date by two and half times for easy reading.
THE OYSTER CASE
Very few people in the world are allowed inside a Rolex Oyster. Only authorised Rolex retailers have the necessary know-how, skills and equipment to gain access. Hermetically sealed to the case with a massive torque of five newton metres, the back of any Oyster, as this case back demonstrates, creates an environment that protects the movement from shocks, pressure, dust, water and any other intrusive element.
