The Omega Speedmaster Professional Chronograph, famously worn on the moon, is a legendary timepiece. Its robust design and impressive history make it a highly sought-after watch. However, even this iconic piece requires occasional time and date adjustments. This comprehensive guide will walk you through the process of setting the time and date on an Omega Speedmaster Automatic Chronograph, specifically focusing on models equipped with the Calibre 9300 movement (though the principles apply to many other Omega Speedmaster automatic movements). We'll also explore some related topics, including where to find the best deals on Omega Speedmaster Automatic watches.
Understanding the Calibre 9300 Movement
The Calibre 9300 is a sophisticated coaxial movement developed by Omega. It offers a range of features, including a chronograph function (stopwatch), a date display, and a central seconds hand. Understanding how these functions interact is crucial for accurate time and date setting.
Setting the Time:
1. Crown Position: The Omega Speedmaster's crown is typically located at 3 o'clock. To set the time, carefully pull the crown out to the first position (usually a gentle pull). This position disengages the time-setting mechanism.
2. Adjusting the Hours and Minutes: Rotate the crown clockwise or counter-clockwise to adjust the hour and minute hands. Remember that the minute hand should move in increments of five minutes per notch on the crown. The hour hand will move accordingly, ensuring correct time synchronization.
3. Returning the Crown: Once the correct time is set, gently push the crown back into its original position. This will re-engage the time-setting mechanism and secure the crown.
Setting the Date:
1. Crown Position: Pull the crown out to the second position (a further pull after the first position). This activates the date-setting mechanism.
2. Adjusting the Date: Rotate the crown clockwise to advance the date. Rotate it counter-clockwise to rewind the date. Crucially, never attempt to adjust the date between 10 PM and 2 AM. This is because the date-changing mechanism is active during this period. Attempting to change the date during this window can damage the movement. It's best to wait until after 2 AM to set the date.
3. Returning the Crown: Once the correct date is set, gently push the crown back into its original position.
Using the Chronograph Function:
The chronograph function is controlled by pushers located on the side of the watch case. Typically, the top pusher starts and stops the chronograph, while the bottom pusher resets it to zero. These functions are independent of the time and date setting mechanisms. Consult your watch's manual for specific instructions on operating the chronograph features.
Important Considerations:
* Gentle Handling: Always handle your Omega Speedmaster with care. Avoid excessive force when operating the crown and pushers.
* Regular Winding: The Omega Speedmaster Calibre 9300 is an automatic movement, meaning it winds itself through the movement of your wrist. However, if the watch hasn't been worn for a while, it might require manual winding. This is usually done by turning the crown clockwise until you feel resistance.
* Professional Service: Regular servicing by an authorized Omega service center is essential to maintain the accuracy and longevity of your watch. This service includes lubrication, cleaning, and inspection of the movement components.
