The Hublot Big Bang chronograph is renowned for its bold design and sophisticated functionality. This article delves into the intricacies of its chronograph function, providing a comprehensive guide for users of various Big Bang models, including the Spirit of Big Bang. We will explore the operation of the chronograph, address common questions, and offer insights gleaned from official Hublot manuals and user experiences.
USING THE CHRONOGRAPH: INTRODUCTION
The chronograph function, a cornerstone of many Hublot Big Bang models, allows for precise time measurement over short intervals. This feature is activated and controlled via two push-pieces strategically positioned on the watch case: the start/stop pusher at 2 o'clock and the reset pusher at 4 o'clock. Understanding their operation is key to effectively using this powerful tool.
OPERATION: A Step-by-Step Guide
The chronograph's operation is remarkably intuitive, despite the complexity inherent in its mechanical workings. The process involves three key steps:
1. Starting the Chronograph: Press the pusher located at 2 o'clock. This initiates the chronograph's measurement, and the central chronograph seconds hand will begin to move, precisely tracking elapsed time. Simultaneously, depending on the specific Big Bang model, other chronograph counters (e.g., 30-minute counter, 12-hour counter) may also begin to record elapsed time.
2. Stopping the Chronograph: Press the same pusher at 2 o'clock again. This halts the chronograph's measurement, freezing the positions of all active chronograph hands at the exact elapsed time. The main timekeeping function of the watch continues to operate independently.
3. Resetting the Chronograph: Press the pusher at 4 o'clock. This resets all chronograph hands (central seconds, minute, and hour counters) back to their zero positions, preparing the chronograph for another measurement. It's crucial to note that the reset function only works when the chronograph is stopped. Attempting to reset while the chronograph is running may damage the movement.
Understanding the Chronograph Counters:
The specific configuration of chronograph counters varies slightly depending on the particular Hublot Big Bang model. Some models feature only a central seconds hand chronograph, while others incorporate additional counters for measuring minutes, hours, and even fractions of a second. These counters provide a comprehensive record of elapsed time, allowing for accurate measurements over longer durations.
For instance, the Big Bang Unico Chronograph Perpetual Calendar incorporates a complex arrangement of counters, reflecting its advanced functionality. Understanding the function of each counter is essential for accurate interpretation of elapsed time. Consult the specific instruction manual for your Hublot Big Bang model to fully grasp the function of each counter.
Common Issues and Troubleshooting:
While the chronograph mechanism is robust, occasional issues may arise. These are often related to improper operation or less frequently, mechanical problems.
* Chronograph Hands Not Moving: Ensure the chronograph has been properly started using the 2 o'clock pusher. If the hands remain stationary after pressing the pusher, the chronograph may require servicing.
* Chronograph Hands Stuck: Do not attempt to force the hands. If the chronograph hands are stuck, immediately consult an authorized Hublot service center. Forcibly manipulating the hands can cause significant damage to the movement.
* Inconsistent Measurements: Inconsistent measurements may indicate a problem with the chronograph mechanism. Again, professional servicing is advised.
