Rolex Sea-Dweller "Single Red"

The Rolex Sea-Dweller with the reference number 126600 impresses with its black dial. In addition, the case has a diameter of 43mm and the Oyster strap is made of stainless steel. The watch has a center second hand and a screw-down crown. It also has a rotating ceramic bezel and a date display. As a chronometer, the watch runs very accurately at all times. The Rolex Sea-Dweller is equipped with the caliber 3235.

The red Sea-Dweller imprint on the dial gave this watch the nickname Single Red.

Rolex uses only Oystersteel for the production of its stainless steel cases. Developed exclusively for Rolex, "Oystersteel" belongs to the category of "904L stainless steels," an alloy used in the high-tech, aerospace and chemical industries that requires the highest corrosion resistance. The "Oystersteel" stainless steel is extremely durable, can be polished to a high shine and retains its beauty even under the most extreme conditions.

The Oyster bracelet is the perfect combination of form and function, aesthetics and technology: introduced in the late 1930s, the three-row metal bracelet with wide, flat and angular elements is extremely durable and comfortable, and is the most popular bracelet in the Oyster collection.

After a deep dive, professional divers must spend some time in a decompression chamber breathing a mixture of oxygen, hydrogen and helium. The tiny molecules of helium, a very light and volatile gas, permeate the entire pressure chamber, including the wristwatch. When the helium decompresses, it can't escape from the sealed case fast enough, creating a pressure differential that could cause the case's glass to explode. To prevent this, Rolex engineers developed a helium valve with a special spring. It automatically responds when the pressure fluctuates by more than 3 to 5 bars, causing the helium valve to open and the pressure to stabilize.
