Rolex Day-Date 40 Ref. 228239

Rolex Day Date 40 - Ref. 228239 - Mamic 1970

The Rolex Oyster Perpetual Day-Date 40 Ref. 228239 in 18 ct white gold with an olive-green dial, fluted bezel and a President bracelet is a watch of an ultimate prestige.

DAY DISPLAY AND THE CYCLOPS LENS

Initially presented in 1956, the Day-Date was a world’s first watch to indicate the day of the week spelt out in full. Worn by many world leaders, the Day-Date is available with a bespoke day display in a wide choice of languages.

The Cyclops lens is one of the most distinctive Rolex features, and one of the most recognizable. Named after the one-eyed giant of Greek mythology, the Cyclops lens magnifies the watch’s emblematic date display two and a half times for easy reading. Behind the Cyclops, as with every feature of a Rolex timepiece, lies a history of invention, research and development, and the endless search for perfection.

OLIVE GREEN DIAL

The sunray finish on Rolex dials is a predominant method in watchmaking of achieving pure metallic colour dials such as shades of silver grey, rhodium or ruthenium. Silver-plating is mostly used as a base layer for the sunray finish, where further colour is added to the prepared dial. Sometimes colours such as champagne are achieved through electroplating with more than half a dozen different metals.

Rolex Day-Date 40 Ref. 228239 features sunray-finish olive green dial.

THE FLUTED BEZEL

The Rolex fluted bezel is a mark of distinction. Originally, the fluting of the Oyster bezel had a functional purpose: it served to screw the bezel onto the case helping to ensure the waterproofness of the watch. It was therefore identical to the fluting on the case back, which was also screwed onto the case for waterproofness, using specific Rolex tools. Over time, the fluting became an aesthetic element, a genuine Rolex signature feature. Today the fluted bezel is a mark of distinction, always in gold.

18 CT WHITE GOLD

By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18 ct gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18 ct gold are obtained: yellow, pink or white. They are made with only the purest metals and meticulously inspected in an in-house laboratory with state-of-the-art equipment, before the gold is formed and shaped with the same painstaking attention to quality. Rolex’s commitment to excellence begins at the source.

THE 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.

SUPERLATIVE CHRONOMETER CERTIFICATION 

Like all Rolex watches, each Day-Date 40 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.
