The Rolex Yacht Master is a sapphire crystal watch designed to function as both a watch and a yacht-race timer. Its Triplock winding crown prevents elements such as water and dust from interfering with its movements. Additionally, it features a chronometer certified by the Contrôle Officiel Suisse des Chronomètres (COSC), meaning it is highly precise regardless of temperature or interfering elements.
Setting the Time
Unscrew the knob, also called the winding crown, on the right side of the watch until it clicks into the second of the two possible positions. The first click will stop the second hand and the second will allow you to set the time.
Turn the winding crown backward or forward until it reaches your desired time.
Push the winding crown back down until it clicks into its original position. The time is now set and the watch hands should resume their movements.
To set the date and to time races, see the detailed Rolex Yacht Master Interactive User Guide in the References section.
