Seven decades of diplomacy and universal craft with the Rolex Oyster Perpetual Day-Date 40
Rolex celebrates seven decades of horological diplomacy with the Oyster Perpetual Day-Date 40, reinforcing its timeless position at the forefront of international affairs and cultural leadership.
When it debuted in 1956, the model made history as the world’s first waterproof self-winding chronometer wristwatch to spell out the day of the week in full in an arc-shaped aperture at twelve o’clock, alongside the signature date display at three o’clock. Over the ensuing seventy years, the distinctive complication has transcended borders, famously gracing the wrists of global visionaries, heads of state, and creative luminaries, earning its enduring moniker as the President’s watch.
Central to this cosmopolitan spirit is the manufacture’s commitment to universal linguistic expression. The bespoke day disc is rendered in a curated selection of 26 languages, thoughtfully encompassing Latin, Cyrillic, Arabic, Hebrew, Japanese, and Chinese scripts to embrace the majority of the world’s diverse writing systems. This technical versatility transforms each dial into an intimate cultural touchpoint, marrying traditional timekeeping with universal communication.
The architectural 40 mm case is fashioned exclusively from proprietary 18-carat yellow gold, poured and meticulously refined in Rolex’s own dedicated foundry to ensure unmatched purity and a warm, enduring lustre. Harmoniously fitted with the iconic three-piece link President bracelet and the brand’s fluted bezel, the exterior houses the in-house calibre 3255. Featuring the patented Chronergy escapement and blue Parachrom hairspring, the self-winding mechanical movement delivers superlative chronometric precision, high resistance to magnetic fields, and a robust 70-hour power reserve.b
True authority requires no translation. In pairing proprietary gold alchemy with an open embrace of world languages, the Day-Date 40 remains an enduring symbol of human ambition, capturing every hour of global history as it unfolds.
