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.
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.
