Rolex watches are renowned for their prestige, craftsmanship, and reliability. A significant aspect of this reputation hinges on the accuracy of their timekeeping. While often perceived as perfectly precise instruments, even Rolex watches exhibit a degree of deviation in their daily rate. Understanding this "Rolex Abweichung," or deviation, is crucial for any owner to manage expectations and appreciate the nuances of mechanical watchmaking. This article will delve into the various aspects of Rolex accuracy, from the manufacturer's claims to post-service performance and the realities of everyday wear.
Zertifizierung als Chronometer der: The cornerstone of Rolex's accuracy claims lies in its chronometer certification. Rolex watches bearing the "Chronometer" designation have undergone rigorous testing by COSC (Contrôle Officiel Suisse des Chronomètres), the official Swiss chronometer testing institute. COSC tests movements in five positions (dial up, dial down, crown up, crown left, and crown right) and at three temperatures (8°C, 23°C, and 38°C) over a period of 15 days. To achieve chronometer certification, a movement must maintain a daily rate within a tolerance of -4 to +6 seconds. This is a significant achievement, demonstrating a higher level of accuracy than a standard watch movement. However, it's crucial to remember that this is a test conducted under controlled laboratory conditions.
Ganggenauigkeit bei Rolex: Rolex, in its marketing materials, typically advertises a daily rate of +2/-2 seconds for its chronometer-certified watches. This means the watch’s timekeeping can deviate by up to four seconds per day, either fast or slow. This advertised range is more stringent than the COSC standard, highlighting Rolex's commitment to precision. It's important to note that this is an *ideal* performance and represents the best-case scenario under optimal conditions. Real-world performance can vary.
Ganggenauigkeit Rolex nach Revision: A Rolex service, often referred to as a "revision," involves a complete overhaul of the movement. This includes cleaning, lubrication, and replacement of worn parts. A properly executed service should significantly improve the watch's accuracy, often bringing it closer to the manufacturer's specified range or even exceeding it. However, even after a revision, the watch's daily rate is not guaranteed to remain perfectly within the +2/-2 seconds range. Several factors can influence post-service performance, as discussed below.
Wie genau läuft deine Uhr wirklich?: The accuracy of a mechanical watch is a complex interplay of various factors. While Rolex strives for optimal precision, several elements can affect the daily rate:
* Position: The position of the watch (on the wrist, lying flat, etc.) can influence its rate. Gravity affects the balance wheel's oscillation, leading to variations.
* Temperature: Temperature fluctuations can also impact the rate. Extreme temperatures, whether hot or cold, can cause the oil to thicken or thin, affecting the movement's efficiency.
* Magnetic fields: Exposure to strong magnetic fields can disrupt the movement's operation and affect its accuracy.
* Shock: Impacts or shocks can damage delicate components, leading to inaccuracies.
* Wear and tear: Over time, components wear down, leading to decreased accuracy. Regular servicing helps mitigate this.
