Cosmograph Daytona Watch: Yellow Rolesor - Oystersteel & 18 CT Yellow Gold - M116503-0004

Rolex Oyster Perpetual
An alluring gold shine and elegance. Steel that excels in robustness and reliability. Each characteristic merges to create a wonderful harmony. The Rolex Oyster Perpetual, an iconic model of Rolex, was adopted in the early 1930s and officially trademarked in 1933. It is the core of the Oyster collection.

Black Dial
The central sweeping second hand allows measurement to 1/8 of a second, while the two counters on the dial measure hours and minutes, displaying elapsed time. These features enable drivers to accurately grasp race times and formulate strategies for victory.

Oyster Bracelet
The design, development, and manufacturing of Rolex bracelets and clasps utilize cutting-edge high-tech technology, along with rigorous testing imposed on the products. Additionally, like all components of the watch, perfect beauty is guaranteed through human inspection. The Oyster Bracelet is a perfect fusion of form and function. It was first introduced in the late 1930s as an extremely robust and superior metal bracelet, consisting of wide, flat three-link designs, making it the most common bracelet in the Oyster collection.

Caliber 4130
The Cosmograph Daytona is equipped with the mechanical automatic chronograph movement, Caliber 4130, developed and manufactured by Rolex. The design of this movement has far fewer components than standard chronographs, thus enhancing the reliability of the movement. Like all of Rolex's perpetual movements, Caliber 4130 is chronometer certified, passing the tests of the Swiss Official Chronometer Testing Institute (COSC), awarded only to high-precision watches. This chronograph movement also features a Parachrom hairspring, which exhibits high durability against shocks and temperature changes.

Start, Drive, Stop
The functions of the Daytona chronograph are activated by pushers that are screwed in like a crown when not in use, ensuring water resistance up to 100m. Pressing the start, stop, and reset functions of the chronograph produces a sharp, crisp sound, achieved through the latest technology. Rolex watchmakers have also invested the highest technical expertise in the mechanism to ensure that the pushers provide the best feel to the fingers when pressed, and that measurements start instantly and accurately without affecting the watch's precision.
