Rolex Day-Date 40 Ref. 228235

Rolex Day Date 40 - Ref. 228235 0025 - Mamic 1970

The Rolex Day-Date is a watch like no other. A true watchmaking icon since 1956, Rolex’s most prestigious model is universally know as the “presidents’ watch”, chosen by the world’s great names for its performance and exceptional presence.

EXCLUSIVITY ACCORDING TO ROLEX

At its launch in 1956, the Day-Date was a major innovation: it was the first calendar wristwatch to indicate, in addition to the date, the day of the week spelt out in full in an arc-shaped window at 12 o’clock – a technical feat at the time. The indication of the day of the week is available in a choice of 26 languages. Watches in the Day-Date range are made only in precious metals – 18 ct yellow, white or Everose gold or 950 platinum.

Worn by many of the world’s political figures, directors and visionaries, the Day-Date is instantly recognizable, in particular thanks to its emblematic President bracelet, whose evocative name, together with the eminent figures who have worn it, ensured the Day-Date became known as the “presidents’ watch”.

Like all models in the prestigious Day-Date range, the Oyster Perpetual Day-Date 40 is made only of precious metals. In addition to the date, it indicates the day of the week spelt out in full in a window on the dial.

GREEN DIAL

The dial is the distinctive face of a Rolex watch, the feature most responsible for its identity and readability. Characterised by hour markers fashioned from 18 ct gold to prevent tarnishing, every Rolex dial is designed and manufactured in-house, largely by hand to ensure perfection.

Marking its 60th anniversary the Rolex Day-Date 40 Ref. 228235 has been given a bright new dial in green, Rolex’s hallmark colour. This special version is available exclusively in 18ct Everose or white gold, featuring the characteristic fluted bezel associated with the model since 1956.

The deconstructed Roman numerals of the Day-Date 40 Ref. 228235 model are made of 18 ct pink gold and polished one by one, on both sides The craftsman operates in the dark with a light directed only at the component, to ensure a level of finish and reflection that no machine could achieve.

The Roman numerals of the Day-Date 40 are minutely faceted and applied by hand, element by element.

PRESIDENT BRACELET

The design, development and production of Rolex bracelets and clasps, as well as the stringent tests they face, involve advanced high technology. And, as with all the components of the watch, aesthetic controls by the human eye guarantee impeccable beauty. The President bracelet, with its semi-circular three piece links, was created in 1956 for the launch of the Oyster Perpetual Day-Date. It represents the ultimate in refinement and comfort and is always made of carefully selected precious metals.

A new-generation concealed attachment beneath the bezel ensures seamless visual continuity between the bracelet and case, for a final aesthetic and functional touch to this sumptuous bracelet.

It takes one full day to polish and satin-finish the President bracelet of a Day-Date 40, link by link, all by hand.

EVEROSE GOLD

Rolex gold is like no other. It is made of only the purest metals, meticulously inspected in an in-house laboratory with state-of-the-art equipment. These metals are alloyed by fusion in a crucible at over 1,000 °C, according to closely guarded formulas to produce the 18 ct yellow, white and Everose gold alloys specific to Rolex.

To preserve the beauty of its pink gold watches, Rolex created and patented a new alloy that it casts in its own foundry: Everose gold. Its characteristic pink hue is attributed to the exclusive composition of the alloy – a Rolex secret – which allows it to maintain its pink colour over time, unlike other pink golds that tend to fade.

To preserve the beauty of its pink gold watches, Rolex created and patented a new alloy: Everose gold, which owes its unique colour – a pink hue unlike any other – to its composition.

SUPERLATIVE CHRONOMETER CERTIFICATION 

Like all Rolex watches, each Day-Date is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This exclusive designation testifies that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria. These certification tests apply to the fully assembled watch, after casing the movement, guaranteeing superlative performance on the wrist in terms of precision, power reserve, waterproofness and self-winding. The precision of a Rolex Superlative Chronometer is of the order of −2/+2 seconds per day, or more than twice that required of an official chronometer.

The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.
