Rolex Oyster Perpetual Day-Date watch in 18 ct yellow gold with diamond hour markers and a fluted bezel.

The watch shown is a Rolex Oyster Perpetual Day-Date, a highly prestigious timepiece nicknamed the "President's watch". 

Key Features

Model: The Day-Date is known for displaying both the day of the week spelled out in full at the 12 o'clock position and the date at the 3 o'clock position, magnified by the distinctive Cyclops lens.

Material: Authentic Day-Date watches are exclusively crafted from solid precious metals (18 ct gold or 950 platinum). The watch in the image appears to be 18 ct yellow gold with a matching gold dial and bracelet.

Bracelet: It features the iconic President bracelet, known for its semi-circular three-piece links and a concealed folding Crownclasp.

Dial: The champagne-colored dial is set with diamond hour markers.

Movement: Most Rolex watches, including the Day-Date, use a mechanical, self-winding movement, resulting in a smooth, continuous sweep of the seconds hand rather than a ticking motion.
