The Breitling Navitimer is an iconic watch, a symbol of aviation history and horological excellence. Its instantly recognizable slide rule bezel and intricate movement have captivated watch enthusiasts for generations. However, even with its legendary status, the Navitimer, particularly those equipped with the in-house B01 movement, have encountered some reported issues, notably concerning the winding mechanism. This article delves into the experiences of Navitimer owners, focusing on reports of excessively loud rotors and difficulties in winding, particularly referencing the often-cited "Navitimer 92 Rotor Laut" – German for "Navitimer 92 Loud Rotor." We'll examine user experiences, potential causes, and what steps can be taken to address these concerns.
The recent surge in online discussions regarding the winding mechanism of the Breitling Navitimer B01 has highlighted a common thread amongst some owners: a noticeably loud rotor and/or difficulty in winding the watch. This isn't a universal experience, but it's prevalent enough to warrant a thorough investigation. Many owners, including myself, who recently acquired a current model Navitimer with the in-house B01 movement, have reported encountering this problem. The contrast between this experience and the smooth, quiet winding of other watches in their collection, such as the mentioned Navitimer World, amplifies the concern.
The issue, often described as a "Navitimer 92 Rotor Laut," isn't solely confined to a specific model year or production batch. Reports span across various Navitimer models equipped with the B01 movement, suggesting a potential design element or manufacturing variance contributing to the problem. Online forums, such as r/breitling, are filled with threads dedicated to this issue, further substantiating its prevalence. One user, referencing their experience with a BLS Breitling Navitimer from Duke, explicitly points to an "extremely loud rotor" as a significant point of contention. The consistent recurrence of this complaint across various sources strongly indicates a need for a closer examination of the potential causes and solutions.
Understanding the B01 Movement and Potential Sources of the Issue:
The Breitling B01 movement is a highly regarded in-house caliber, known for its robustness and reliability. It's a self-winding movement, meaning it utilizes the motion of the wearer's wrist to wind the mainspring. This process is facilitated by a rotor, a weighted component that spins freely within the movement, transferring energy to the mainspring. The noise often associated with the "Navitimer 92 Rotor Laut" issue is likely stemming from one or more of the following factors:
* Rotor Bearing Friction: The rotor's smooth operation depends on its bearings. If these bearings are not perfectly lubricated or show signs of wear, increased friction can lead to a noticeable whirring or clicking sound. This is particularly noticeable during the winding process and can be exacerbated by factors like temperature changes or impacts.
* Rotor Balance and Alignment: Even minor misalignments or imbalances in the rotor can amplify its noise. A slightly skewed rotor might rub against internal components, leading to an audible sound. This is often not noticeable during normal wear but becomes apparent when actively winding the watch.
