The Omega Speedmaster Professional Moonwatch. A name synonymous with legendary space exploration, rugged reliability, and a timeless design. But even this iconic timepiece, with its robust construction, requires a degree of understanding to fully utilize its capabilities. This article delves into the intricacies of the Omega Speedmaster's buttons, providing a comprehensive guide covering operation, functionality, and troubleshooting, drawing upon the expertise found in official Omega manuals and supplementing that with practical advice. We'll explore how to use the chronograph functions, address common queries regarding settings, and offer clarity on the often-asked questions surrounding the crown and pushers.
Understanding the Omega Speedmaster's Control System: Crown and Pushers
The Omega Speedmaster's chronograph functionality is controlled primarily through its crown and two pushers located on the right side of the case. These components, expertly crafted and meticulously engineered, are the gateway to the watch's impressive timing capabilities. Incorrect handling can lead to malfunctions, so understanding their precise function is crucial.
1. The Crown: The crown, the largest control element, serves multiple purposes:
* Time Setting: Unscrewing the crown (usually counter-clockwise) allows you to pull it out to different positions. The first position typically allows you to adjust the date, while the second position allows you to set the time. Pushing the crown back in and screwing it down securely is essential to maintain water resistance. Always refer to your specific Omega Speedmaster model's instructions, as the crown operation can vary slightly depending on the movement and year of manufacture. Remember, forceful manipulation of the crown can damage the delicate internal components.
* Hand Winding (if applicable): Some Omega Speedmaster models, particularly older ones, feature a manual-winding movement. In these cases, the crown can be used to manually wind the mainspring, ensuring power reserve even without wearing the watch continuously. This is typically achieved by turning the crown clockwise in the first position. Overwinding should be avoided, as it can damage the movement.
2. The Pushers: The two pushers situated on either side of the crown control the chronograph functions:
* Upper Pusher (Start/Stop): Pressing this pusher starts the chronograph seconds hand. Pressing it again stops the chronograph.
* Lower Pusher (Reset): Pressing this pusher returns all chronograph hands (seconds, minutes, and hours) to their zero positions. This action should only be performed when the chronograph is stopped.
Omega Speedmaster How to Use: A Step-by-Step Guide
Let’s break down the chronograph operation into a clear sequence:
1. Starting the Chronograph: Ensure the chronograph hands are at zero. Press the upper pusher. The chronograph seconds hand will begin moving, recording elapsed time.
2. Stopping the Chronograph: Press the upper pusher again. The chronograph seconds hand will stop, freezing the elapsed time.
3. Resetting the Chronograph: Press the lower pusher. All chronograph hands will snap back to their zero positions.
Omega Speedmaster Timer Settings: Understanding the Chronograph Registers
The Omega Speedmaster's chronograph features three registers (sub-dials) on the dial:
* Small Seconds Register: This register, typically located at the 9 o'clock position, displays the running seconds of the watch's main timekeeping function, independent of the chronograph.
