The Rolex Submariner, a legend in the world of dive watches, is renowned not only for its iconic design and robust build but also for the precision and reliability of its movements. This article delves into the specifications of the movements powering the latest generation of Submariners, specifically the Caliber 3230 and its close relative, the Caliber 3235. We'll also explore the broader context of Rolex Submariner models, their history, pricing, and where to find genuine examples.
The Heart of the Beast: Caliber 3230 & 3235
The 3230 and 3235 movements represent the pinnacle of Rolex's in-house manufacturing capabilities. These self-winding mechanical movements are not simply timekeeping instruments; they are meticulously crafted pieces of horological engineering designed to withstand the rigors of even the most demanding underwater environments. While sharing a similar architecture, there are subtle differences.
The Caliber 3230, found in the no-date Submariner (Reference 124060), is a refined and efficient powerhouse. Its key specifications include:
* Self-winding: The movement utilizes a Perpetual rotor, automatically winding the mainspring through the wearer's wrist movements, eliminating the need for manual winding. This ensures consistent power reserve.
* Power Reserve: The 3230 boasts an impressive power reserve of approximately 70 hours. This allows the watch to continue running for a significant period even if it's not worn for a couple of days.
* Jewels: Precisely crafted jewels reduce friction within the movement, contributing to its smooth operation and longevity. The exact number of jewels varies slightly depending on the specific version, but it's typically around 31.
* Frequency: The balance wheel oscillates at a frequency of 28,800 vibrations per hour (4 Hz), contributing to accurate timekeeping.
* Paramagnetic Blue Parachrom Hairspring: This patented hairspring, made from a paramagnetic alloy, is resistant to magnetic fields and temperature variations, ensuring greater accuracy and stability.
* Chronometer Certification: Like all Rolex movements, the 3230 is a COSC-certified chronometer, meaning it has passed rigorous testing for precision and accuracy.
The Caliber 3235, featured in Submariner models with a date (like the 126610LN), builds upon the 3230's foundation and adds the date complication. This necessitates a slightly more complex mechanism, but the performance characteristics remain exceptionally high:
* Self-winding: Similar to the 3230, it's a self-winding movement with a Perpetual rotor.
* Power Reserve: The power reserve remains a substantial 70 hours.
* Jewels: The jewel count is slightly higher than the 3230, reflecting the added complexity of the date mechanism.
* Frequency: The frequency remains at 28,800 vibrations per hour (4 Hz).
* Paramagnetic Blue Parachrom Hairspring: The 3235 also utilizes the highly resilient and precise Paramagnetic Blue Parachrom hairspring.
* Chronometer Certification: It also holds the prestigious COSC chronometer certification.
