The iconic Rolex crown, synonymous with luxury and precision, immediately catches the eye. However, many Rolex models, particularly those designed for sporting activities, feature additional buttons on the side of the case. These buttons aren't merely decorative elements; they play a crucial role in the functionality of the watch, often controlling complex chronograph or GMT functions. This article delves into the purpose and operation of these side buttons, focusing primarily on the Rolex Cosmograph Daytona and the GMT-Master II, two prominent examples showcasing this feature. We will also address common misconceptions and provide guidance on proper usage.
Understanding the Rolex Chronograph Function (Daytona)
The most common reason for side buttons on a Rolex is the presence of a chronograph function. The Rolex Cosmograph Daytona is the quintessential example. This celebrated timepiece boasts two pushers – buttons – located on either side of the crown. These buttons are not merely decorative; they are integral to the operation of the chronograph, a mechanism for precisely measuring elapsed time.
* The Upper Pusher (Typically at 2 o'clock): This button is the start/stop button. Pressing it once initiates the chronograph, starting the sweep seconds hand and any other chronograph counters (e.g., minute and hour counters). Pressing it again stops the chronograph, freezing the elapsed time measurement.
* The Lower Pusher (Typically at 4 o'clock): This button is the reset button. It returns all chronograph hands – the seconds, minute, and hour counters – to their zero positions. This button is typically only used *after* the chronograph has been stopped. Attempting to reset while the chronograph is running could damage the movement.
Mastering the Rolex Chronograph: A Step-by-Step Guide
1. Starting the Chronograph: Press the upper pusher once. The sweep seconds hand will begin to move, indicating the start of the timing function. Simultaneously, the minute and hour counters (depending on the Daytona model and its complications) will also begin recording elapsed time.
2. Stopping the Chronograph: Press the upper pusher again. The sweep seconds hand, minute counter, and hour counter will stop, displaying the elapsed time.
3. Resetting the Chronograph: Press the lower pusher. All chronograph hands will return to their zero positions, preparing the chronograph for another measurement. It's crucial to ensure the chronograph is stopped before resetting.
Important Considerations for Rolex Daytona Owners:
* Gentle Pressure: Avoid excessive force when using the pushers. Gentle, deliberate presses are sufficient to activate the chronograph functions. Overly forceful pressure could potentially damage the delicate mechanism.
* Regular Servicing: Like all mechanical watches, the Daytona requires regular servicing by a qualified Rolex technician. This ensures the chronograph mechanism remains accurate and reliable.
* Understanding the Complications: Different Daytona models may have slightly different chronograph configurations. Consult the official Rolex instructions or a certified watchmaker for specific details regarding your model.
The Rolex GMT-Master II and its Functionality
The Rolex GMT-Master II, renowned for its ability to display multiple time zones simultaneously, also features a pusher, but its function differs significantly from the Daytona's chronograph pushers.
The GMT-Master II typically features a single pusher located at the crown. This pusher allows the user to independently adjust the 24-hour hand, which indicates a second time zone. By pressing and turning the crown, the user can quickly adjust the 24-hour hand forward or backward in one-hour increments. This allows for quick and easy adjustments to the second time zone without affecting the primary timekeeping function of the watch.
