The Rolex 3135 movement, a workhorse of the brand for decades, is renowned for its reliability and precision. Understanding its intricate components is crucial for both watchmakers and enthusiasts alike. This article focuses on a specific, yet vital, part: the setting lever (part # 3135-220), exploring its function, significance, and place within the broader context of the 3135 movement and its successors. We will also delve into related topics, addressing common questions and concerns surrounding the 3135 and its comparisons to other Rolex calibers.
The Rolex 3135 Setting Lever (Part # 3135-220): A Critical Component
The setting lever, designated as part # 3135-220, is a small but crucial component within the Rolex 3135 movement. It acts as the intermediary between the crown and the gear train responsible for setting the time. When the crown is pulled out to the time-setting position, the setting lever engages with the various gears, allowing the hour and minute hands to be adjusted. Its precise operation is essential for accurate time setting and prevents accidental time changes.
The quality of the setting lever directly impacts the smooth and reliable operation of the time-setting function. A worn or damaged setting lever can lead to difficulties in setting the time, slippage, or even damage to other parts of the movement. This is where the availability of replacement parts, such as the generic 3135-220 offered by companies like Gleave & Co., becomes important. These companies often manufacture generic parts with high-quality materials and excellent dimensional accuracy, offering a cost-effective alternative to original Rolex parts while maintaining a high level of functionality. The positive customer feedback associated with these generic parts suggests a satisfactory level of performance and reliability.
Rolex 3135 Movement vs. Fraud: The Importance of Authenticity
The popularity of the Rolex 3135 movement has unfortunately led to a rise in counterfeit watches. Distinguishing a genuine Rolex 3135 from a fraudulent imitation requires careful examination. While a detailed technical analysis might be necessary for definitive authentication, certain visual cues and functional tests can help identify potential red flags. Inconsistencies in markings, poor finishing, and deviations from the known specifications of the 3135 movement are strong indicators of a counterfeit. The presence of a correctly functioning setting lever, while not a guarantee of authenticity, is a necessary component of a genuine 3135. A poorly functioning or incorrectly fitted setting lever could be a telltale sign of a fake.
