Rolex Unveils New Caliber and Updated President's Day-Date

Watch collectors and watch lovers alike all have a grand affinity for Rolex. This brand has been on the cutting edge of time since its inception. After all, Rolex did introduce the first water resistant watch, the Oyster, back in the 1920s and made headlines around with world with it when Mercedes Gleitz swam the English Channel wearing the watch, which still worked when she emerged from the water.

Then, in 1956, the brand unveiled the Rolex Day-Date watch – created by founder Hans Wilsdorf. The watch is also often referred to as the President’s watch because of the great number of important presidents and socialites who have worn it.

Now, Rolex brings its famed Day-Date model to new heights consistent with the 21st century. The brand has built the all-new Caliber 3255 mechanical movement that further underscores the dial description of “Superlative Chronometer.”

The caliber, which was years in the making, surpasses the criteria developed by the COSC for certified chronometers thanks to a new chronometrically precise mechanical system. In fact, the technology in this timepiece holds 14 individual patents. The bidirectional self-winding Caliber 3255 beats at 4 Hz (or 28,800 vibrations per hour), and consists of several cool new inventions that are typical of Rolex’s innovative and advanced spirit. Among them are the following: the blue Parachrom hairspring, large balance wheel with variable inertia weights, state-of-the-art Chronergy escapement with Paramagnetic nickel-phosphorus pallet fork and escape wheel. For rugged functionality, the movement also is equipped with high-performance Paraflex shock absorbers. All of these inventions together make this timepiece both more accurate and more efficient – with 70 hours of power reserve.

The new Day-Date watches are offered with either a top-quality leather strap or with the much-loved President’s bracelet, which has also been improved and updated with features such as ceramic inserts inside the link, and a concealed attachment to the case – both for added wear and durability. The watch will be created in a 40mm version that will complement the existing 36mm version, and will be offered in yellow gold and platinum.
