The Breitling name is synonymous with aviation-inspired timepieces, robust construction, and high-performance movements. Many of their iconic chronographs rely on a workhorse movement that has defined a generation of watchmaking: the Valjoux 7750 (or its near-identical ETA 7750 and Sellita SW500 counterparts). Understanding this movement is key to appreciating the value and heritage embedded in many Breitling watches. This article will explore the Breitling Automatic Valjoux 7750, delving into its technical intricacies, its place in the market of affordable Valjoux 7750 watches, and the associated costs involved. We'll also examine the closely related ETA 7750 movement and its price point, providing a comprehensive overview for both enthusiasts and potential buyers.
The ETA 7750 Technical Guide: A Foundation of Excellence
Before discussing the Breitling implementation, let's establish a firm understanding of the ETA 7750, the movement that serves as the basis for many variations, including those found in Breitling watches. This automatic chronograph caliber is a true legend in the watchmaking world, renowned for its reliability, robustness, and relatively low cost compared to in-house movements. Its widespread adoption by numerous brands testifies to its quality and versatility.
The ETA 7750 boasts a robust construction, typically incorporating 25 jewels for reduced friction and enhanced longevity. It operates at a frequency of 28,800 vibrations per hour (4 Hz), offering a relatively high level of precision for an automatic chronograph. The movement is a column-wheel chronograph, meaning that the chronograph functions are controlled by a column wheel, offering a smoother, more precise operation compared to cam-actuated systems. This adds to the overall quality and feel of the chronograph pushers.
The ETA 7750 is a modular movement, meaning that the chronograph module is added onto a base automatic movement. This modularity contributes to its cost-effectiveness and allows for various configurations and complications to be added relatively easily. Its layout is well-regarded for its ease of servicing and repair, further contributing to its appeal among watchmakers. The movement also features a date complication, usually displayed at the 3 o'clock position. The layout of the sub-dials can vary slightly depending on the brand and model.
The Sellita SW500: A Worthy Copy?
As mentioned in the introduction, the Sellita SW500 is essentially a clone of the Valjoux 7750. While not directly produced by the original Valjoux (now part of ETA), Sellita has engineered a very close equivalent, often considered a direct competitor to the ETA 7750. This offers a viable alternative for brands looking for a reliable and cost-effective chronograph movement, contributing to the availability of affordable Valjoux 7750-based watches in the market. The Sellita SW500 shares many of the same technical specifications and operational characteristics as the ETA 7750, making it a suitable replacement or alternative in many applications. The subtle differences between the SW500 and the ETA 7750 are usually minimal and often only noticeable to experienced watchmakers.
