The Rolex Datejust is an iconic timepiece that has been a symbol of elegance and precision since its introduction in 1945. At the heart of the Datejust is the impressive Rolex 3135 movement, a caliber known for its reliability, accuracy, and craftsmanship. In this article, we will delve into the intricate details of the Rolex 3135 movement, exploring its technical specifications, unique features, and comparisons to other movements in the Rolex lineup.
Technical Specifications of the Rolex 3135 Movement
The Rolex 3135 movement is a self-winding mechanical movement that is based on 31 jewels, which serve as bearings for the various moving parts within the caliber. These jewels reduce friction and wear, ensuring smooth operation and longevity of the movement. One of the standout features of the Rolex 3135 movement is its calendar aperture, which changes instantaneously at midnight. This instantaneous date change is a testament to the precision engineering of the movement, allowing for seamless functionality without any lag or delay.
Another notable feature of the Rolex 3135 movement is the balance wheel, which is made of glucydur, a high-performance alloy known for its stability and resistance to temperature variations. The balance wheel is a critical component of the movement, oscillating back and forth at a precise frequency to regulate the timekeeping of the watch. The use of glucydur in the balance wheel ensures optimal performance and accuracy, even in varying environmental conditions.
The Rolex 3135 movement also features two pairs of adjusting screws on the balance wheel, allowing for precise regulation of the movement's rate. These adjusting screws enable watchmakers to fine-tune the accuracy of the watch, ensuring that it meets the stringent standards set by Rolex. The meticulous attention to detail in the design and construction of the Rolex 3135 movement is a testament to Rolex's commitment to excellence and precision in watchmaking.
Comparisons and Considerations
When comparing the Rolex 3135 movement to other movements in the Rolex lineup, such as the 3235 caliber, there are several key differences to consider. The Rolex 3235 caliber, introduced in 2015, offers enhanced performance and features compared to the 3135 movement. The 3235 caliber boasts a longer power reserve of approximately 70 hours, compared to the 48-hour power reserve of the 3135 movement. Additionally, the 3235 caliber incorporates Rolex's patented Chronergy escapement, which enhances energy efficiency and precision.
