The Breitling Navitimer, a legendary pilot's watch renowned for its iconic slide rule bezel and sophisticated design, presents a unique challenge for those needing to access its inner workings. Unlike many watches with simple case backs, the newer models of the Breitling Navitimer boast a complex, multi-faceted case back – typically featuring 15 sides – requiring specialized tools and expertise for removal. This complexity, coupled with the potential for damage, makes opening a Navitimer case back a task best left to experienced professionals. This article delves into the intricacies of this process, addressing common issues and providing a comprehensive overview for watch enthusiasts and professionals alike.
The Challenge of the 15-Sided Case Back
The design of the newer Breitling Navitimer case backs presents a significant hurdle for anyone attempting to open them. The 15-sided configuration necessitates the use of specialized case back opening tools, specifically designed to grip the intricate angles without causing damage to the delicate case. These tools are not standard fare in most watchmaker's kits; they are specialized and often expensive. The difficulty stems from several factors:
* Precise Fit: The tools must perfectly match the specific dimensions of the case back. Given that there are over ten different sizes of these case backs across various Navitimer models and generations, having a complete set of tools is a significant investment. A poorly fitting tool risks slipping, potentially scratching or damaging the case back irreparably.
* High Torque Resistance: Breitling often uses a robust sealing mechanism, frequently involving a strong adhesive or gasket, to ensure water resistance. This makes opening the case back significantly more challenging than with watches employing simpler designs. Excessive force can lead to case back damage or even damage to the movement itself.
* Material Sensitivity: The case back material, often stainless steel or precious metals, requires careful handling to avoid scratching or marring the surface. Improper tools or techniques can easily lead to visible imperfections.
Why Professional Jewellers Often Decline the Job
Many professional jewellers, despite their expertise in handling delicate items, often decline to open a Breitling Navitimer case back. This is due to several factors:
* Liability Concerns: The risk of damaging a valuable watch, especially one as complex as a Navitimer, is significant. The cost of repair or replacement could far outweigh the potential profit from the opening procedure.
* Lack of Specialized Tools: As mentioned, the specialized tools needed are not commonly found in every jeweller's workshop. Investing in a comprehensive set of these tools is a substantial expense, justified only by a high volume of Breitling Navitimer repairs.
* Time Constraints: Opening a Navitimer case back is a time-consuming process, requiring precision and patience. Jewellers often have a busy schedule, and dedicating the necessary time to this intricate task might not be economically feasible.
Breitling Navitimer Stuck on Back: Common Scenarios
Several scenarios can lead to a stuck Breitling Navitimer case back, further complicating the removal process:
* Epoxy or Adhesive: Breitling frequently uses epoxy or a strong adhesive to ensure water resistance. This adhesive can harden over time, making removal extremely difficult. Attempting to force it open can lead to significant damage.
* Corrosion: Over time, corrosion can occur between the case back and the case, further binding them together. This often requires specialized cleaning and loosening techniques before attempting removal.
