Rolex – Oyster Perpetual Day-Date 40 and new Calibre 3255
At Baselworld 2015, Rolex disclosed another release of its Oyster Perpetual Day-Date, quite possibly the most renowned and fruitful models of the Geneva brand.
Specifically, the new Rolex Oyster Perpetual Day-Date 40 highlights a smoothed out plan, another size and, most importantly, another mechanical development which addresses the new age of Rolex developments.
As far as plan, we note refined drags and center case, a wide and clear dial and the re-visitation of the President wristband – initially presented for the Day-Date in 1956 – updated for a superior joining into the Oyster case. Water impervious to 100 meters/330 feet, the new case has a breadth, as the name proposes, of 40 mm.
This year the new Day-Date 40 is introduced in valuable metals just: platinum (ref. 228206), yellow gold (ref. 228238), white gold (ref. 228239), or Everose gold (ref. 228235). While all gold references have fluted bezels, a smooth bezel portrays the platinum model.
The new references are accessible in an assortment of new dials: ice blue with askew theme on sunray finish for the platinum, champagne with sunray finish for the yellow gold, silver with quadrant theme for the white gold and sundust with stripe theme on sunray finish for the Everose gold.
The new Day-Date is outfitted with another age development, the 4Hz (28,800 vph) Calibre 3255. Backed by 14 licenses and altogether created and made by Rolex, the new type offers the most significant level of execution at any point accomplished by Rolex. Guaranteed as a Swiss chronometer by COSC (Swiss Official Chronometer Testing Institute), it is tried a second time by Rolex subsequent to being cased to guarantee that in everyday use it fulfills Rolex’s standards for exactness, which are twice pretty much as demanding as those for an authoritatively confirmed chronometer.
More than 90% of the development parts have been overhauled and upgraded, from those that produce and store energy (self-winding module and heart) to the managing organ liable for exactness (oscillator), the stuff train and the escapement.
The new development consolidates the protected Chronergy escapement which, because of its calculation, improves the effectiveness of this critical component by 15%. As a clear advantage, the force save stretches out to three days (around 70 hours), addressing an expansion of 24 hours (or 50%) compared to that of the past age. Made of nickel-phosphorus, the Chronergy escapement is additionally unfeeling toward attractive impedance.
The President arm band is presently furnished with fired additions inside the connections, improving its gracefulness and solidness. Another disguised connection underneath the bezel guarantees consistent visual progression between the wristband and case.
We expect that a steel adaptation of the Rolex Day-Date 40 will be dispatched next year. rolex.com
