The Breitling Navitimer, the Chronomat, the Avenger – these iconic timepieces share a common thread, a workhorse movement that has powered countless wristwatches for decades: the Valjoux 7750. While Breitling has developed its own in-house movements, the 7750 remains a cornerstone of their production, and understanding its intricacies, particularly the number and function of its jewels, is key to appreciating its enduring appeal. This article will delve into the Breitling 7750 movement, exploring its design, its jewel count, and its place within Breitling's broader horological landscape. We'll also touch upon other Breitling movements to provide a comprehensive overview of the brand's mechanical prowess.
Breitling 7750 Movement: The Foundation of Success
The Valjoux 7750, now primarily produced by ETA as the ETA 7750 (and often rebranded by various watch manufacturers), is a self-winding, high-grade chronograph movement. Its ubiquity stems from its robust construction, relatively high accuracy, and versatility. This movement is a column-wheel chronograph, meaning the chronograph functions are controlled by a column wheel, providing a smoother, more precise operation than a cam-actuated system. The 7750's architecture allows for a wide range of complications and customizations, making it attractive to brands like Breitling seeking a reliable base for their watches.
One crucial aspect of the 7750, and of any mechanical movement, is the use of jewels. These synthetic rubies (or sometimes sapphires) are strategically placed in the movement to reduce friction and wear on critical components, particularly pivots. The reduction in friction leads to increased efficiency, longevity, and improved accuracy. The precise number of jewels can vary slightly depending on the manufacturer and specific modifications, but the ETA 7750 typically boasts 25 jewels. This jewel count reflects the movement's complexity and the number of points where friction needs to be minimized.
Breitling Chrono 7750 Movement: The Breitling Adaptation
When Breitling incorporates the 7750 into its watches, it's not simply a matter of dropping the movement in and calling it a day. Breitling often modifies and enhances the 7750 to meet its specific design and performance requirements. While the core architecture remains the same, Breitling might adjust the finishing, add decorations, or incorporate bespoke components to align with its brand identity and the specific watch model. These modifications might subtly alter the appearance of the movement when viewed through the exhibition case back, but the fundamental jewel count generally remains at 25.
The choice of the 7750 by Breitling underscores the movement's reliability and suitability for their diverse range of chronographs. The robust nature of the 7750 makes it ideal for the active lifestyles often associated with Breitling's target audience. The 7750's ability to withstand the rigors of daily wear, combined with its precise timekeeping and chronograph functions, ensures that Breitling watches equipped with this movement maintain a high level of performance.
