Acciaio Oystersteel: The Foundation of Durability

The Sea-Dweller 126600, along with many other Rolex watches, utilizes *Acciaio Oystersteel*. This isn't just any stainless steel; it's 904L stainless steel, a high-performance alloy renowned for its exceptional resistance to corrosion. Rolex uses this specific grade of steel because it maintains its beauty even in the harshest environments. Its superior corrosion resistance makes it an ideal choice for a diving watch constantly exposed to saltwater. Beyond its functional benefits, 904L steel also polishes to a higher sheen than standard stainless steel, contributing to the overall luxurious feel of the watch.

The Calibre 3235: A Movement of Precision and Reliability

Powering the Sea-Dweller 126600 is the Calibre 3235, a self-winding mechanical movement entirely developed and manufactured by Rolex. This movement represents a significant upgrade over its predecessors, offering improved accuracy, efficiency, and reliability. Key features of the Calibre 3235 include:

* Chronergy Escapement: This patented escapement, made of nickel-phosphorus, is insensitive to magnetic fields and enhances the movement's energy efficiency.

* Optimized Gear Train: The optimized gear train improves the transmission of power from the mainspring to the escapement, contributing to the increased power reserve.

* Paramagnetic Blue Parachrom Hairspring: Made from a paramagnetic alloy, the Parachrom hairspring is up to 10 times more resistant to shocks and temperature variations than traditional hairsprings. This greatly enhances the accuracy and stability of the movement.

* High-Capacity Barrel: The movement boasts a larger barrel, which accommodates a longer mainspring, resulting in an extended power reserve of approximately 70 hours.

The Calibre 3235 is a Superlative Chronometer, certified by COSC (Contrôle Officiel Suisse des Chronomètres) and further tested by Rolex after casing to meet their stringent accuracy standards of -2/+2 seconds per day. This certification guarantees exceptional precision and performance.
