The Rolex Calibre 3235 is a marvel of modern horology, a self-winding movement lauded for its accuracy, power reserve, and sophisticated features. It represents a significant leap forward for Rolex, incorporating improvements over its predecessor, the 3135, and powering many of the brand's popular models, including the GMT-Master II (126710BLRO, 126710BLNR, etc.), the Submariner (126610LN, 126610LV), and the Sea-Dweller (126600). However, despite its advanced design and reputation for reliability, reports of specific issues with the 3235 movement have emerged, raising concerns among both enthusiasts and owners. This article delves into these reported problems, exploring the experiences of owners like the one who reported experiencing the issue twice with a 126710 and once with a 126600, and examining the broader context of the movement's performance and the implications for Rolex's quality control.
The issue in question centers around a gradual slowdown of the movement, often manifesting as a decreasing balance amplitude. This isn't a sudden stop or catastrophic failure; rather, it's a more insidious problem requiring specialized equipment, like a timing machine, to detect. The owner's experience, where Rolex RSC (Rolex Service Center) simply "turned up" something, suggests a potential adjustment to the regulation, a common fix for minor timing discrepancies. However, the recurrence of the problem across multiple watches raises questions about the root cause. Is this a simple matter of individual watch regulation, or is there a deeper, systemic issue within the 3235 movement itself?
Understanding the Rolex Calibre 3235 Automatic Movement:
Before delving into the reported problems, it's crucial to understand the intricacies of the Rolex Calibre 3235. It's a completely in-house designed and manufactured movement, a testament to Rolex's commitment to vertical integration. Key features include:
* Chronometer Certification: Like many Rolex movements, the 3235 is officially certified as a chronometer by COSC (Contrôle Officiel Suisse des Chronomètres), signifying its accuracy within strict tolerances.
* Paramagnetic Escape Wheel: Made from a nickel-phosphorus alloy, this component is highly resistant to magnetic fields, a significant improvement over traditional escape wheels.
* Improved Power Reserve: Offering a 70-hour power reserve, significantly longer than the 48 hours of the 3135, the 3235 allows for greater convenience and less frequent winding.
* Optimized Efficiency: Rolex claims improved efficiency and reduced friction thanks to its innovative architecture and materials.
* Improved Date Change Mechanism: The 3235 features a smoother and more reliable date change mechanism compared to its predecessor.
Rolex 3235 Movement Price:
The price of a Rolex 3235 movement is not publicly available as a standalone component. The movement's value is intrinsically tied to the complete watch it powers. The cost of repair or replacement would depend entirely on the context and the Rolex Service Center's assessment. This lack of transparency is consistent with Rolex's exclusive approach to its in-house movements.
