When we originally published this article, Rolex utilized both the 3135 and the 3235 calibers concurrently. This was a transitional period where models not yet updated retained the older 3135 caliber, notably including some Submariner models. However, today, the landscape has shifted. The venerable 3135, a workhorse movement that powered countless Rolex watches for decades, has been entirely superseded. The Rolex Calibre 3235 now reigns supreme as the brand's flagship automatic movement, powering a significant portion of their most popular models. This review will delve deep into the 3235, examining its features, improvements over its predecessor, potential issues, and overall performance. We'll also address common searches like "Rolex 3235 problems," "Rolex 3135 vs 3235 caliber," and the elusive "Rolex 3235 movement for sale" market.
The Evolution from 3135 to 3235: A Quantum Leap in Precision
The Rolex Calibre 3135, a highly reliable and robust movement, enjoyed a long and successful run. However, Rolex, ever striving for perfection, recognized the potential for improvement. The 3235 represents a significant advancement, boasting several key enhancements that elevate its performance and longevity:
* Chronometer Certification: Both movements hold the prestigious COSC (Contrôle Officiel Suisse des Chronomètres) chronometer certification, guaranteeing a high level of accuracy. However, the 3235's superior design contributes to even greater precision in real-world conditions.
* Escapement: The 3235 features a redesigned escape wheel and pallet fork, constructed from a novel nickel-phosphorus alloy. This material boasts superior anti-magnetic properties and enhanced resistance to wear, contributing to improved long-term accuracy and reliability. The 3135, while robust, lacked this advanced material and design.
* Improved Power Reserve: The 3235 boasts a significantly improved power reserve of 70 hours compared to the 3135's 48 hours. This longer power reserve offers greater convenience, allowing wearers to put the watch down for a weekend without needing to reset it. This is a substantial upgrade for those who frequently rotate their watch collection.
* Paramagnetic Blue Parachrom Hairspring: The 3235 incorporates Rolex's patented Paramagnetic blue Parachrom hairspring, a significant improvement over the traditional hairspring found in the 3135. This hairspring is significantly more resistant to magnetic fields and shocks, ensuring greater accuracy and resilience in daily wear. Its unique blue color is also a distinguishing visual feature.
* Optimized Efficiency: The 3235 features a redesigned architecture that improves overall efficiency, contributing to the extended power reserve and enhanced accuracy. Rolex's commitment to meticulous design is evident in the movement's refined energy management.
* Improved Date Mechanism: While both movements feature a date function, the 3235's date-changing mechanism is refined for smoother operation and enhanced reliability.
