The Breitling Bentley Flying B Jump Hour, a watch renowned for its unique and captivating complication, isn't without its share of potential issues. While generally considered a stylish and mechanically interesting timepiece, several recurring problems have been reported by owners, prompting discussions on forums like Rolex Forums (a surprisingly common place for discussions about other brands) and necessitating a detailed examination of the common faults and potential solutions. This article delves into the reported problems associated with the Breitling Bentley Flying B Jump Hour, specifically focusing on the A283612 model and similar variations like the A2836212/C722, offering insights into troubleshooting, maintenance, and service options.
Understanding the Jump Hour Complication:
Before diving into the problems, it's crucial to understand the mechanism at play. The jump hour complication is inherently more complex than a standard hour hand movement. Instead of smoothly sweeping across the dial, the hour hand "jumps" to the next hour at the stroke of the hour. This requires additional components and precise synchronization, making it more susceptible to malfunctions compared to simpler movements. The Breitling Bentley Flying B Jump Hour utilizes a modified ETA movement (often based on the ETA 2892-A2 or similar), which has been adapted to incorporate this intricate feature. This modification, while enhancing the watch's aesthetic appeal, also introduces potential points of failure.
Common Breitling Bentley Flying B Jump Hour Problems:
Numerous issues have been reported by owners of the Breitling Bentley Flying B Jump Hour. These problems can broadly be categorized into:
1. Hour Jump Issues: This is arguably the most common problem. The hour hand may fail to jump precisely at the hour mark, resulting in:
* Delayed Jumps: The hour hand might lag behind, jumping only after several minutes past the hour.
* Missed Jumps: In more severe cases, the hour hand might entirely miss a jump, rendering the time inaccurate.
* Erratic Jumps: The jump might be inconsistent, sometimes occurring promptly and other times delayed or missed.
These issues often stem from problems within the jump hour mechanism itself. Worn or damaged components, lubrication issues, or even minute dust particles can interfere with the precise timing of the jump. The delicate nature of this complication necessitates careful handling and regular servicing.
2. Power Reserve Issues: While not directly related to the jump hour mechanism, power reserve problems can indirectly impact its function. A low power reserve might result in the jump hour mechanism failing to operate correctly, leading to inaccurate timekeeping. This could be due to:
* Worn Mainspring: The mainspring is responsible for storing energy. Over time, it can weaken, reducing the power reserve and affecting the watch's overall performance, including the jump hour function.
* Lubrication Problems: Insufficient or degraded lubrication can increase friction within the movement, consuming more energy and shortening the power reserve.
* Dirty Movement: Accumulated dirt and debris can impede the movement's efficiency, impacting power reserve and potentially causing other complications.
3. Date Complications (if applicable): Some models incorporate a date complication alongside the jump hour. Issues with the date function, such as incorrect date setting or date wheel skipping, can sometimes be linked to underlying problems within the movement, potentially affecting the jump hour mechanism as well.
4. General Movement Problems: Beyond the specific jump hour and date complications, owners have also reported general movement problems, such as:
