Rolex Oyster Perpetual 31 277200

The Essence of the Oyster Perpetual

As the direct descendant of the world’s first waterproof wristwatch, the Oyster Perpetual 31 carries forward a legacy of functional elegance that has defined the brand since 1926. The reference 277200 distills the Rolex experience into its most fundamental elements, offering a versatile mid-size case that transitions seamlessly from casual to formal environments.

Uncompromising Oystersteel Construction

The 277200 is forged from Oystersteel, a high-performance alloy belonging to the 904L steel family. This material is most commonly used in high-technology, aerospace, and chemical industries where maximum resistance to corrosion is essential. Once polished, Oystersteel maintains its luster even in the harshest environments, providing a brilliant finish that complements the smooth, domed bezel. The dial is protected by a scratch-resistant sapphire crystal, ensuring the face of the watch remains clear and legible over decades of use.

Technological Excellence: Calibre 2232

At the heart of this reference is the Calibre 2232, a self-winding mechanical movement entirely developed and manufactured by Rolex. Introduced in 2020, this movement features the patented Syloxi hairspring in silicon. The Syloxi hairspring is completely insensitive to magnetic fields and remains up to ten times more precise than a traditional hairspring when subjected to shocks. Its unique geometry ensures that the watch maintains its Superlative Chronometer precision of −2/+2 seconds per day, regardless of the watch’s orientation.

The Original Oyster Bracelet

The 277200 is fitted on the legendary Oyster bracelet, a masterpiece of form and function first introduced in the late 1930s. This three-piece link bracelet is known for its robustness and comfort, featuring the Oysterclasp and the Easylink comfort extension. This system allows the wearer to increase the bracelet length by approximately 5mm, providing an immediate adjustment to account for changes in wrist size due to temperature or activity.
