Rolex made significant strides in the 1910s and 1920s, focusing on precision and reliability. In 1910, Rolex became the first wristwatch to receive a Swiss certificate of chronometric precision from the Official Watch Rating Centre in Bienne, Switzerland. This achievement set the foundation for the brand's reputation for producing some of the most accurate watches in the world.

The brand relocated its headquarters to Geneva, Switzerland, in 1919. This move was strategic, as Geneva was already a hub for fine watchmaking. Rolex continued innovating, introducing the first waterproof wristwatch, the Oyster, in 1926, which further solidified the brand’s position as a leader in both functionality and luxury.

Rolex watches are meticulously crafted in Switzerland. The brand operates multiple facilities, including the main production site in Geneva and others in Biel/Bienne, where key components like movements and cases are manufactured. Swiss made watches carry a level of prestige and trust, and Rolex’s commitment to craftsmanship ensures that every timepiece meets the highest standards.

The company also maintains tight control over its supply chain by producing many components in-house. From gold casting to movement assembly, Rolex watches embody the essence of Swiss precision, contributing to the brand’s worldwide allure.

One intriguing fact about Rolex is its ownership structure. Unlike most luxury brands, Rolex is privately owned by the Hans Wilsdorf Foundation, a charitable organization established by the brand's founder. After the death of Hans Wilsdorf in 1960, ownership transferred to the foundation, ensuring that the company could remain independent. This unique structure allows Rolex to reinvest profits into research and development while supporting charitable causes.

Throughout Rolex history, the brand has built a strong connection with sports and exploration. The introduction of the Oyster Perpetual in 1931, the world’s first waterproof and self-winding watch, was a game-changer. Rolex watches soon became a favorite among adventurers and athletes alike.

Rolex played a pivotal role in significant expeditions, such as Sir Edmund Hillary and Tenzing Norgay's historic ascent of Mount Everest in 1953. The Rolex Explorer, inspired by this achievement, remains one of the brand’s most iconic models.

In the world of sports, Rolex is known for sponsoring prestigious events such as Wimbledon, the US Open, and Formula 1 racing. Its partnership with these events reinforces the brand's association with excellence and performance.

The Rolex Submariner, introduced in 1953, was the first wristwatch waterproof to a depth of 100 meters, making it a favorite among divers. In 1956, the Day Date model was launched, becoming the first watch to display both the day and the date on the dial. These groundbreaking innovations set the standard for the modern wristwatch and further expanded Rolex’s influence in the luxury watch industry.

Another notable milestone came in 1967, with the release of the SeaDweller, a watch designed for deep sea diving. With a helium escape valve, it allowed professional divers to explore the ocean's depths without compromising the watch's integrity. These developments have made Rolex a preferred brand not just among collectors but also professionals in demanding fields.
