Day-Date 40Oyster, 40 mm, platinum

The Oyster Perpetual Day-Date 40 in Platinum with a bright black, diamond-set dial, smooth 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.

Bright black 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.
