Rolex presents its iconic Oyster Perpetual Day-Date with a
fresh aesthetic and a new-generation mechanical movement, Calibre 3255, inside
a 40 mm case. From a design perspective, this new Day-Date features refined
lugs and case middle, a large dial opening, and an exclusive return to the
President bracelet that is more closely integrated into the Oyster case. The
movement has COSC certification (Contrôle Officiel Suisse des Chronomètres) yet
in fact complies with precision criteria that are twice as exacting. It
incorporates the patented Chronergy escapement which combines high energy
efficiency with dependability. Made from nickel-phosphorus, it is also
insensitive to magnetic interference. The oscillator has an optimized blue
Parachrom balance spring. New barrel architecture and the escapement's greater
efficiency ensure a power reserve of 70 hours.
