The Breitling Navitimer, a watch synonymous with aviation history and sophisticated design, is renowned for its iconic slide rule bezel. This rotating bezel, crucial for performing complex calculations, can unfortunately sometimes become problematic. A common complaint among Navitimer owners is a seized or stiff bezel, often described as "klemmt" (stuck) in German. This article delves into the reasons behind a jammed Navitimer bezel, exploring potential solutions, preventative measures, and the importance of professional servicing for this intricate timepiece. We'll specifically focus on the Navitimer Automatic 41, but many of the principles apply across the Navitimer range. You can find the official manual for the Navitimer Automatic 41 online, readily downloadable as a PDF, which provides basic operational instructions, including details on the rotating bezel's functionality (although it may not explicitly address troubleshooting jammed bezels).
Understanding the Navitimer's Bezel Mechanism:
Before tackling the problem of a stuck bezel, let's understand its mechanics. The Navitimer's rotating bezel isn't simply a decorative element; it's a precision-engineered component with several interlocking parts. The bezel itself is typically made of high-quality materials like stainless steel or precious metals. It interacts with a series of carefully positioned springs, ratchets, and click mechanisms. These components allow for the precise, incremental rotation of the bezel, crucial for accurate calculations. Over time, these components can wear down, become clogged with debris, or suffer from lubrication issues, leading to the frustrating experience of a jammed bezel.
Causes of a Jammed Navitimer Lünette:
Several factors can contribute to a Breitling Navitimer bezel becoming stuck:
* Lack of Lubrication: The intricate mechanisms within the bezel rely on proper lubrication to function smoothly. Over time, the lubricant can dry out, causing friction and ultimately leading to a seized bezel. This is perhaps the most common cause of a jammed bezel.
* Dirt and Debris: Dust, sand, and other small particles can accumulate within the bezel's mechanism, obstructing its movement. This is particularly true for watches exposed to harsh environments.
* Wear and Tear: Like any mechanical component, the bezel's internal parts are subject to wear and tear from regular use. The springs and ratchets can weaken or break, resulting in a stiff or completely immobile bezel.
* Manufacturing Defects: While rare, manufacturing defects can also contribute to bezel issues. A poorly assembled or flawed component can lead to a jammed bezel from the outset.
* Impact Damage: A significant impact to the watch, such as a drop or collision, can damage the bezel's internal components, causing it to seize.
* Corrosion: Exposure to moisture or corrosive substances can damage the bezel's metallic parts, causing them to bind and jam.
Troubleshooting a Stuck Bezel:
Before resorting to professional servicing, you can attempt some basic troubleshooting steps:
1. Gentle Cleaning: Carefully inspect the bezel for any visible debris. Using a soft-bristled brush and compressed air (carefully avoiding excessive pressure), try to remove any dirt or particles. Avoid using harsh chemicals or abrasive cleaners, as these can damage the bezel's finish.
