The Rolex 1130 movement, a testament to the brand's unwavering commitment to precision and reliability, represents a significant chapter in the history of horological innovation. While not as widely discussed as some of its more prolific siblings, like the 3135 or the 2836, the 1130 holds a special place, particularly amongst enthusiasts of certain Rolex models. This article delves into the intricacies of the Rolex 1130 movement, providing comprehensive information for owners, collectors, and watchmakers alike. Here you can find useful information for the repair and maintenance of your watches, covering specifications, comparisons, and a broader context within the larger family of Rolex calibers.
Rolex Caliber 1130 Movement – Specifications and Photo
Unfortunately, finding a readily available, high-resolution photograph of the Rolex 1130 movement disassembled is challenging. Rolex maintains a tight control over its proprietary information, and detailed technical drawings are not publicly released. However, we can discuss its key specifications based on available information from watchmakers and collectors:
* Type: Automatic, self-winding mechanical movement
* Jewels: The exact jewel count is difficult to pinpoint definitively without access to official Rolex documentation, but sources suggest it's likely in the range of 28-31 jewels, a common number for movements of this complexity. Jewels reduce friction within the movement, contributing to longevity and accuracy.
* Power Reserve: Typically around 48 hours, allowing the watch to continue running even if it's not worn for a period of time. This is a standard power reserve for many contemporary Rolex movements.
* Frequency: The balance wheel likely oscillates at 28,800 beats per hour (8 beats per second), a common standard for high-quality mechanical watches. This high frequency contributes to improved accuracy.
* Features: The 1130 is known for its reliability and robust construction, incorporating features designed for shock resistance and longevity. It is likely to include a free-sprung balance for improved timekeeping. Specific details about its escapement mechanism (likely a lever escapement) and other internal components are limited in publicly available information.
* Date Function: The 1130 movement almost certainly includes a date function, a common feature in many Rolex models. The date is typically displayed in a window at the 3 o'clock position.
While a detailed photograph isn't readily available, imagining the 1130 would reveal a meticulously crafted mechanism, showcasing the hallmarks of Rolex's manufacturing expertise: finely finished bridges, polished screws, and intricate gearing.
