It consists of multiple configurations such as a case, crown, mirror, bezel, and helium exhaust valve.

The Rolex Oyster case, patented in 1926, was named after Rolex founder Hans Wilsdorf. This technology locks the bezel, crown, and bottom cover to the middle point.

Rolex mirror magnifying glass

The calendar magnifying glass on the mirror is the iconic feature of Rolex. Rolex first launched a calendar magnifier in 1953 and applied for a patent. Later, famous watches such as Panerai, TAG Heuer, and Chopard also used the mirror calendar magnifying glass because the patent protection period of Rolex had passed.

Rolex calendar magnifying glass

Originally, Rolex’s mirror was made of acrylic glass, and the calendar magnifier was also made of acrylic. Therefore, it is not resistant to scratches, which is why many antique Rolex and magnifying glasses will be damaged. Since the 1970s, Rolex began to replace the sapphire watch mirror, and the calendar magnifying glass was also replaced with sapphire glass, which has improved hardness and scratch resistance. In 2005, Rolex added an anti-reflective coating to the calendar magnifying glass so that the calendar is more transparent and will not be affected by reflections until today.

The early Rolex magnifying glass was made of acrylic.

Now the Rolex mirror magnifying glass is a sapphire mirror.

Rolex bezel

One of the critical configurations of the Rolex sports model on the Oyster case is the bezel. The first bezel used by Rolex in the 1950s was a resin plastic bezel. It was used in the early GMT, and the plastic bezel needed to be more durable. Soon in 1956, Rolex replaced the plastic bezel with an aluminum ring. Rolex had used aluminum bezels for a very long time until after 2000 when it was replaced with the current ceramic bezel.

Rolex’s current ceramic ring was first launched in 2005 and was used on the GMT 116718 that year. After that, all Rolex sports models were replaced with ceramic coils. The ceramic ring is scratch-resistant, does not fade, and is always bright and new. In 2013, Rolex’s ceramic bezel launched a two-color bezel for the first time. The red and blue bezel was first released, then there were blue and black circles and black and brown circles (Sars circle) until today.

Rolex Oyster case helium escape valve

There is a helium exhaust valve on the diving watch case with a waterproof depth of 1220 meters and 3990 meters, such as the Rolex Sea-Dweller and DEEPSEA (officially called the deep dive model in Chinese). According to Rolex’s description, people engaged in deep-sea infrastructure work will live in a pressurized cabin in the deep sea for a period, and the gas breathed in the house is mixed with helium. Helium will enter the watch to prevent the helium from “breaking” the look and causing the mirror to fall off when the pressure of the helium changes. Rolex developed and patented an automatic helium escape valve in 1967. The helium exhaust valve will automatically release the helium in the case according to the pressure change. It continues to this day.

The Rolex DDPSEA is gradually blue, and the small disc on the side of the case can be seen, which is the helium exhaust valve.

We can see a small disc on the side of the case of Sea-Dweller and DEEPSEA, which is the helium exhaust valve. There is a spring in the helium exhaust valve. When the pressure changes, the spring will push the small disc on the top to open a small gap, and the helium will be discharged.
