Ten highlights in the history of diving watches


Ten highlights in the history of diving watches

In the beginning, the dive watch was just a pure tool: an essential swimming partner to help divers arrive on time, thereby extending their life. Today, they are something else: fashion statements, conversation fragments, rough companions when traveling to the beach or swimming pool. This is an excerpt from the timeline: “Ten Years of Diving Watches”, which traces the history of the first truly waterproof case invented by diving watches from the 1920s to 2014. (Including mechanical watches only.)

1. Rolex Oyster (1926)

In 1926, the diving watch appeared. They have an insulated top (the top is the main entrance for water into the enclosure). It was also this year that Rolex founder Hans Wilsdorf (Hans Wilsdorf) introduced an oyster case with a screw-in crown, screw-in back cover and tightly sealed crystal glass. This is the world’s first truly waterproof box. A year later, Wilsdorf invited the stenographer Mercedes Gratz to try to become the first British woman to swim across the English Channel wearing oysters. She did not succeed all the way, but the Rolex around her neck kept ticking.

2. Panerai prototype (1936)

The Italian Navy commissioned Panerai to develop the first prototype of the watch, which will evolve into what is now called the “Radiomir” model. These watches are water resistant to 30 meters and will be put into production in two years. Early Radiomir watches had a Rolex movement and a special case with a diameter of 47 mm. They were named after radium, allowing the dial to be clearly identified even in muddy water.

3. Blanca ping 50? (1953)

Blancpain launched the first dive watch 50? This watch is water resistant to 100 meters. (Fifty? Equal to 300 feet, or about 91 meters. This was the maximum depth that a diver could reach with equipment at the time. This watch was made at the request of Captain Bob Marubier, an agent. During World War II, he had Worked for the British and later became the captain of the French Army’s combat diving team. He asked Blancpain to make a watch with a black dial, large Arabic numerals, clear indications and a rotating bezel. “In fact, we hope that every logo is like a shepherd. People’s guiding lights are as clear as the light,” Malubière later recalled.

4. Panerai Crown Protection (1956)

Panerai obtains a patent for the curved crown to protect the bridge. Now the emblem of the company’s Luminor series, the splint contains a locking cam lever that pushes the crown toward the housing so that it fits tightly with the seal of the crown. 5. Breitling’s first dive watch (1957)

Breitling launched the first dive watch Superocean. This watch is water-resistant to 200 meters, partly because of its hard (one-piece) case and exceptionally strong crystals. The bezel of the watch can be locked in place so that it will not be knocked into place while diving. The chronograph version of this watch came out in 1959.

6. The first Rolex (1967)

Rolex has introduced a sea-building model, which is a deeper version of the submarine model. Its distinguishing feature is its helium valve, through which helium can be released into the case of the diving chamber. This watch was produced at the request of the Comex company (Comex), which specializes in deep-sea diving equipment and services, mainly for offshore oil and gas exploration. The watch is water-resistant to 610 meters.

7. The first dive computer (1983)

Launched the first dive computer. In the 1990s, the use of dive computers became popular, and dive watches were mainly downgraded to backup equipment.

8. The International Organization for Standardization invented the standard for diving watches (1996)

The International Organization for Standardization (ISO) has published standard 6425, which defines the functions that a watch must have before it can be designated as a “diving” watch. They include water resistance requirements (the water resistance of the watch must be 25% higher than the water resistance claimed on the dial), underwater legibility, thermal shock resistance, and the ability to measure elapsed time. The 6425 standard replaced the standard published in 1984 and is still valid today.

9. CX Swiss Army 20,000 feet (2009)

CX Swiss military launched 20,000 feet, breaking the Rolex deep-sea waterproof record (20,000 feet equals 6,100 meters) and entering the Guinness World Record. (CX Ruijun has maintained a depth record from 2005 until the deep sea appeared in 2008. This watch is a chronograph with a case thickness of 28.5 mm and a dome on the back. According to the CX Swiss military, it is actually The upper is waterproof to 7500 meters, provides a safety margin of 25%, and meets the requirements of ISO 6425.

10. International Whaling Commission Marine Timer Series (2014)

IWC updated the marine timepiece series, equipped with a two-way outer ring and a one-way inner ring. The most waterproof nautical chronograph automatic watch 2000 in the new nautical chronograph models is water-resistant to 2000 meters.
