Day-Date 40Oyster, 40 mm, yellow gold and diamonds

The Oyster Perpetual Day-Date 40 in 18 ct yellow gold with a champagne-colour dial, diamond-set 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.

Diamond-Set Bezel

A sparkling symphony

Gem-setters, like sculptors, finely carve the precious metal to hand-shape the seat in which each gemstone will be perfectly lodged. With the art and craft of a jeweller, the stone is placed and meticulously aligned with the others, then firmly secured in its gold or platinum setting.
