The Breitling Avenger Bandit and the Navitimer 1884 Special Edition represent two distinct yet powerful entries in Breitling's extensive catalog. Both boast impressive chronograph functionalities, but recent experiences with the 12-hour totalizer hand on these models have highlighted some potential points of interest for owners and enthusiasts. This article delves into the mechanics of these chronographs, focusing on the observed behavior of the 12-hour counter and providing context through comparisons with other Breitling movements, specifically referencing information that might be found in Breitling GMT manuals, Breitling watch manuals (PDF), and Breitling B04S manuals. We will explore potential causes for any observed irregularities and offer guidance on what steps to take if you encounter similar issues.
Understanding the Chronograph Mechanism:
Before addressing the specific issue of the 12-hour totalizer hand, it's crucial to grasp the fundamental mechanics of a chronograph movement. A chronograph is essentially a sophisticated stopwatch integrated into a watch. It involves a complex interplay of gears, levers, and springs that allow for precise time measurement. The chronograph function typically includes three main counters:
* Seconds counter: This is the most commonly used counter, typically completing a full revolution in 60 seconds.
* Minutes counter: This counter records the elapsed minutes, usually completing a full revolution in 60 minutes.
* Hours counter (12-hour totalizer): This counter records the elapsed hours, completing a full revolution in 12 hours.
The specific implementation of these counters varies across different watch movements and manufacturers. Breitling employs its own proprietary movements, and the precise mechanics can differ significantly between models like the Avenger Bandit and the Navitimer 1884. Understanding the differences is vital to diagnosing any potential issues.
The Avenger Bandit and its Movement:
The Breitling Avenger Bandit often utilizes Breitling's in-house movements or modified versions of ETA movements. Precise details on the specific caliber used will depend on the year of manufacture and specific model variant. Consulting a Breitling Avenger Bandit manual (often available as a PDF download from the Breitling website or authorized retailers) is crucial for precise information regarding the movement's specifications and operation. The manual should provide a detailed explanation of the chronograph function and the expected behavior of the different counters.
The 12-hour totalizer hand's behavior on the Avenger Bandit, as reported by the owner, suggests a potential issue. While precise details are needed to ascertain the nature of the problem, several possibilities exist:
* Gear wear or lubrication issues: Over time, the gears within the chronograph mechanism can experience wear and tear, potentially leading to inaccuracies in the 12-hour counter. Inadequate lubrication can exacerbate this issue, causing the gears to bind or move erratically.
* Timing issues: A slight misalignment or malfunction within the chronograph mechanism can lead to the 12-hour totalizer hand not advancing at the correct rate. This could manifest as the hand moving too slowly, too quickly, or skipping increments.
* Mechanical failure: In more severe cases, a mechanical failure within the chronograph module itself might be the culprit. This could range from a broken spring to a damaged gear.
