Oyster Perpetual, Lady-Datejust 28
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 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.
Fitted with a Syloxi hairspring in silicon, patented by Rolex, calibre 2236 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.
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 Rolex-patented Easylink rapid extension system that allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.
The Oyster Perpetual, Lady-Datejust 28 is sold for around $7,955 (£6,009).
