Breitling, a name synonymous with precision and aviation heritage, has long been associated with high-quality timepieces. But what exactly constitutes the "Breitling Automatik Genauigkeit," or accuracy of Breitling automatic watches? This article delves into the intricacies of mechanical watch accuracy, focusing specifically on Breitling's automatic movements and addressing common questions surrounding their precision and performance. We'll explore the factors influencing accuracy, examine specific Breitling models, and compare them to industry standards.
The provided snippets of text, referencing a forum post from November 4th, 2008, discussing the accuracy of Breitling watches, highlight the ongoing interest in this topic. The questions raised – concerning daily rate deviation ("Welche Gangabweichung bei Automatik"), the most accurate watches ("Was sind die genauesten Uhren der Branche?"), and specific model performance (Chronomat Automatic GMT 40) – underscore the key considerations for potential buyers. Let's unpack these elements in detail.
Genauigkeit von Breitling Uhren (Accuracy of Breitling Watches): A Multifaceted Perspective
The accuracy of a mechanical watch, especially an automatic one, is not a fixed number. It's influenced by numerous factors, including:
* The Movement: The caliber, or movement, is the heart of the watch. Breitling uses a variety of in-house and outsourced movements, each with its own specifications regarding accuracy. Their in-house movements, like the Caliber B20 (mentioned in the provided text), are often designed for robustness and precision, while movements sourced from other manufacturers may exhibit varying levels of accuracy. The design, manufacturing tolerances, and the number of jewels all impact performance.
* Regulation: The regulation of the watch is crucial. This involves adjusting the balance wheel and hairspring to optimize the rate. A well-regulated watch will maintain a consistent rate within its specified tolerance. Breitling watches undergo quality control checks, but individual variations can still occur.
* Environmental Factors: Temperature, magnetism, and even gravity can subtly affect a mechanical watch's accuracy. Extreme temperatures can cause the oil to thicken or thin, altering the movement's performance. Magnetic fields can disrupt the balance wheel's oscillations. Positional differences (wearing the watch on the wrist versus laying it flat) can also lead to variations in rate.
* Wear and Tear: Over time, wear and tear on the movement components can affect accuracy. Regular servicing and maintenance are essential to maintain optimal performance. Oil degradation, component wear, and the accumulation of dust and debris can all contribute to decreased accuracy.
* Individual Variation: Even within the same model and caliber, individual watches will exhibit slight variations in accuracy. This is inherent to the nature of mechanical watchmaking; no two watches are exactly alike.
Welche Gangabweichung bei Automatik (Daily Rate Deviation in Automatic Watches): Understanding COSC Certification
A common metric for assessing accuracy is the daily rate deviation, often expressed in seconds per day. Many Breitling watches, particularly those in their higher price ranges, are certified by the Contrôle Officiel Suisse des Chronomètres (COSC). COSC certification signifies that the watch movement has passed rigorous testing, demonstrating a daily rate deviation within a specified range (-4 to +6 seconds per day). However, it’s important to note that even COSC-certified watches might exhibit slightly different performance after leaving the factory due to the factors mentioned above.
