Day-Date 40Oyster, 40 mm, white gold
The Oyster Perpetual Day-Date 40 in 18 ct white gold with a meteorite, diamond-set dial, fluted bezel and a President bracelet.
The Day-Date was the first watch to indicate the day of the week spelt out in full when it was first presented in 1956.
Meteorite dial
From across the Solar System
Meteorite comes from the heart of an asteroid or possibly even a planet that has exploded, propelling material across the Solar System until chance brings it into our planet’s orbit and gravity pulls it to Earth.
During its journey, the centre of the meteorite is gradually transformed, producing highly unusual metallic patterns, resulting from the very slow cooling of molten asteroid cores. The designers at Rolex create from these configurations a unique treasure for some of the most prestigious models, including this Day-Date 40.
