Innovation is part of Rolex‘s heritage. At the beginning of the 20th century, only large marine chronometers could keep time accurately, and in 1914, Rolex became the first watch brand to receive “A” chronometer certification from the prestigious Kew Observatory in the United Kingdom. Although the idea of a waterproof and dustproof watch seemed impossible at the time, in 1926 Rolex created the world’s first waterproof wristwatch, the Oyster, and displayed it in a water-filled fish tank in a shop window.

Since then, Rolex has filed for more than 400 patents and broadened its various areas of watchmaking, which have evolved over the years to become the watch icon it is today. Rolex has filed for two patents for this unique process, which, besides mastering the entire method of making ceramic parts, allowed it to create the two-tone Cerachrom insert. With its clever technology, it has overcome technical challenges that were once thought unbeatable.

Ceramics are made from a mix of powders with different chemical properties and binders to help shape the ceramics. The resulting wet clay is pressed under high pressure to form a blank bezel. The first high-temperature treatment removes the binder, leaving only the ceramic. This is a crucial step in changing half of the red circle to blue. This bezel is then injected with a chemical solution, and great care is needed to ensure the bezel absorbs the solution properly. The mixture’s formulation must also balance the concentration and amount of the solution. During the sintering phase, two colors become visible.
