The Oyster Perpetual Day-Date 40 in 18 ct white gold with a silver, 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.
Silver dial
A watchmaking technique
The sunray finish creates delicate light reflections on many dials in the Oyster Perpetual collection. It is obtained using masterful brushing techniques that create grooves running outwards from the centre of the dial.
