The Oyster Perpetual Day-Date 40 in 18 ct Everose gold, with a chocolate, diamond-set dial, diamond-set bezel and a President bracelet.
Its dial features 10 baguette-cut diamonds. 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.
Chocolate Dial
A watchmaking technique
The sunray finish on Rolex dials is a predominant method in watchmaking of achieving pure metallic colour dials such as shades of silver grey, rhodium or ruthenium.
