Designed to withstand the extreme conditions of deep-sea diving, the Sea-Dweller Black Dial model is a testament to Rolex’s commitment to innovation and quality. This article explores the features and specifications of the Rolex Sea-Dweller Black Dial, showcasing its impeccable design and advanced functionality.
Case and Material
The Rolex Sea-Dweller Black Dial features a robust 43mm case made from Oystersteel, a high-performance alloy developed by Rolex. Oystersteel is known for its exceptional resistance to corrosion and its ability to maintain a polished finish in even the harshest environments. The 43mm size provides a substantial presence on the wrist while ensuring readability and functionality under water.
Crystal and Bezel
Protecting the dial is a domed sapphire crystal, renowned for its scratch resistance and clarity. This crystal ensures that the dial remains pristine and legible, even after rigorous use.
The watch is equipped with a unidirectional rotatable bezel featuring a Chroma insert. This bezel allows divers to accurately track their dive time, a critical feature for safety underwater. The Chroma insert enhances the bezel’s durability and legibility, ensuring that the elapsed time can be read at a glance.
Movement
At the heart of the Rolex Sea-Dweller Black Dial is the Rolex Caliber 3235, a self-winding mechanical movement entirely developed and manufactured by Rolex. This movement is equipped with a Paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, offering greater resistance to shocks and magnetic fields. The Caliber 3235 ensures exceptional accuracy and reliability, with a power reserve of approximately 70 hours.
Dial and Hands
The black dial of the Sea-Dweller is designed for maximum legibility in low-light conditions, featuring Chroma Light hour markers and hands. These markers and hands are filled with long-lasting luminescent material, providing a blue glow that enhances readability underwater. The date window at the 3 o’clock position is equipped with the Cyclops lens for easy viewing.
Bracelet
The watch is fitted with the iconic Oyster bracelet, known for its robustness and comfort. The bracelet is equipped with a folding Oysterlock safety clasp, which prevents accidental opening, and the Rolex Glidelock extension system, allowing for precise adjustments without the need for tools. This feature is particularly useful for divers who need to adjust the bracelet to fit over their wetsuits.
