This article delves into the intricacies of restoring a vintage Breitling Navitimer, focusing on the process of removing the stem (Stellwelle in German), a crucial step in any comprehensive overhaul. While this article uses a replica Navitimer as an example, the principles and cautions discussed apply equally to genuine vintage Breitling Navitimers. The expertise required for such work should not be underestimated; attempting this without proper training and tools can irrevocably damage a valuable timepiece. This article supplements a short video demonstrating the disassembly process (link provided in the introduction), offering a more in-depth exploration of the related topics and considerations involved.
The video showcases the dismantling of a replica Breitling Navitimer, offering a visual guide to removing the stem, a critical component often requiring attention during restoration. The full restoration video (link provided in the introduction) expands on this initial step, illustrating the meticulous cleaning, lubrication, and reassembly required to bring a vintage timepiece back to its former glory. While focusing on a replica, the techniques and challenges are remarkably similar to those encountered when restoring a genuine Breitling Navitimer.
Understanding the Navitimer's Complexity:
The Breitling Navitimer, a legendary chronograph renowned for its slide-rule bezel and exceptional craftsmanship, presents unique challenges during restoration. Its intricate mechanism, composed of numerous components working in perfect harmony, demands a high degree of skill and precision. The stem, or Stellwelle, is a pivotal part of this mechanism, connecting the crown to the internal workings of the movement, enabling time setting and winding. Removing the stem without proper knowledge can easily lead to damage, highlighting the importance of careful and methodical disassembly.
This process is particularly relevant in discussions surrounding Breitling Navitimer bezel repair, Breitling bezel replacement, and even noob Navitimer bezel replacement, as the stem often needs to be removed to access the bezel assembly for maintenance or replacement. The bezel, a defining feature of the Navitimer, is prone to wear and tear over time, requiring periodic attention. Understanding the stem removal process is thus crucial for anyone undertaking such repairs, whether on a genuine or replica Navitimer.
The Importance of Proper Tools and Techniques:
Before attempting any disassembly, acquiring the correct tools is paramount. A specialized watchmaker's tool kit is essential, including various screwdrivers, tweezers, and a stem removal tool. Improper tools can easily damage delicate components, resulting in costly repairs or even rendering the watch unusable. The video demonstrates the proper use of these tools, emphasizing the importance of gentle pressure and controlled movements.
The process of removing the Stellwelle itself is not straightforward. It often involves carefully depressing the stem release button, located within the movement, while simultaneously gently pulling the stem outward. Forcing the stem can cause damage to the stem itself or the movement. The video provides a visual guide to this process, but hands-on experience and training are crucial for mastering this technique.
