Lady-DateJust 28

Prestige and elegance

Rolex is introducing a 904L steel version of its classic Oyster Perpetual Lady-Datejust 28, as well as a white Rolesor version (combining 904L steel and 18 ct white gold) with a fluted or gem-set bezel in 18 ct white gold. These new versions are available with a wide choice of dials. As with the gold and the Rolesor versions introduced in 2015 and 2016, these new Lady-Datejust watches feature a redesigned, larger 28 mm case and a new-generation mechanical movement, calibre 2236, equipped with the Rolex patented Syloxi hairspring in silicon.

Like all Rolex watches, the new versions of the Lady-Datejust 28 carry the Superlative Chronometer certification redefined by Rolex in 2015, which ensures singular performance on the wrist.

THE TIMELESS CLASSIC FOR WOMEN

Rolex’s classic feminine watch, the Lady-Datejust 28, is in the lineage of the Datejust, the emblematic model that has been a byword for style and accurate timekeeping ever since its launch in 1945. The first women’s version of this date chronometer, the Lady-Datejust, appeared in the late 1950s, bringing the heritage of timeless elegance and functionality to a smaller size perfectly suited to a lady’s wrist.

THE OYSTER CASE, SYMBOL OF WATERPROOFNESS

The Oyster case of the Lady-Datejust 28, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness, proportion and elegance. Its characteristic middle case is crafted from a solid block of 904L steel. Its fluted case back is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. The winding crown, fitted with the Twinlock double waterproofness system, screws down securely against the case. The crystal, with a Cyclops lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof sapphire. The waterproof Oyster case provides optimum protection for the Lady-Datejust 28’s high-precision movement.

PERPETUAL CALIBRE 2236

The new Lady-Datejust 28 watches are equipped with calibre 2236, a new-generation self-winding mechanical movement entirely developed and manufactured by Rolex. Fitted with a Syloxi hairspring in silicon, patented by Rolex, it offers a superlative level of chronometric performance. Insensitive to magnetic fields, the Syloxi hairspring provides great stability in the face of temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks. Its patented geometry ensures its regularity in any position.

Calibre 2236 is equipped with a self-winding module via a Perpetual rotor and offers a power reserve of approximately 55 hours.

OYSTER AND JUBILEE BRACELETS

The new Lady-Datejust 28 in 904L steel and the white Rolesor version are available on an Oyster or Jubilee bracelet. Both bracelets benefit from the new concealed attachment system beneath the bezel, which ensures seamless visual continuity between the bracelet and case. The Jubilee bracelet, with a redesigned profile, is fitted with the new-generation concealed Crownclasp, opened with a hinged Rolex crown. The Oyster bracelet is fitted with a folding Oysterclasp as well as the ingenious Rolexpatented Easylink rapid extension system that allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.

SUPERLATIVE CHRONOMETER CERTIFICATION

Like all Rolex watches, the Lady-Datejust 28 is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This exclusive designation testifies that the watch has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria, which exceed watchmaking norms and standards. The certification applies 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 after casing 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.
