Since the birth of life from the blue sea, the depth and mystery have become the spiritual sacred place where humans desire to return. Diving, diving into the water, is a popular game and a spiritual belief. Blancpain, ‘the founder of classic timepieces’, is passionate about the ocean. The diving skills seem to have been incorporated into the brand’s genes.
Blancpain’s association with the ocean can be attributed to Jean-Jacques Fiechter, then president of the brand in the 1950s. He is passionate about diving. In 1952, he created a watch based on his diving experience and needs, and named it ‘Fifty Fifty’. ‘噚’ is an English unit used to measure water depth. 1 噚 is equivalent to 1.8288 meters. The inspiration for naming this watch the Fifty Fathoms was derived from Shakespeare’s famous book ‘The Storm’, which was loved by Mr. Fichte. At that time, fifty centimeters (about 91.4 meters) were considered to be almost the ultimate depth that divers can dive. Not long after, Mr. Fichte took his new watch into the deep ocean together while diving in southern France. Since then, the diving world has reached a new milestone. Blancpain’s Fifty Fathoms watch has become the originator of modern diving watches.

The first officially launched Fifty Fathoms watch in history
In 1953, two French naval officers, Colonel Robert Bob Maloubier and Lieutenant Claude Riffaut were commissioned to create the French Frogman Dive Commando. Professional diving watches are a must in military equipment that needs to be prepared. After rigorous testing, the Blancpain Fifty Fathoms watch has stood out and has since become the French Navy’s standard equipment, accompanying French diving commandos to perform various underwater military operations. From 1953 to the end of the 1970s, Blancpain produced more than 20 professional diving watches of different models, different sizes and different functions for multinational naval forces and submarine research teams. In addition to France, Including the United States, Germany, Spain, Israel, Sweden, Norway, Finland, and more. Blancpain’s Fifty Fathoms watch is a modern professional diving watch that has been tested in actual combat.

Literature and art
In 1956, Jacques-Yves Cousteau, a French marine ecologist and film director, filmed the world’s first marine documentary in the history of the world’s cinema to record the underwater wonders of the ocean— ‘Silent World’. The film won two Golden Palm awards for best photography and best film at the 9th Cannes Film Festival in 1956, the best documentary feature award at the 29th Academy Awards in 1957, and the British Academy of Film and Television Arts in 1957. Award nomination. . Among them, Blancpain Fifty Fathoms was selected by director Jacques Cousteau for the diving scene of his film. Accompanied by Fifty Fathoms, the explorers in the film have been baptized by storms at sea, bloody face-to-face with sharks and whales, and also encountered various marine wonders and sailing fun.

Since 2012, Blancpain has joined National Geographic’s Pristine Seas Expeditions, a collection of exploration, research and protection. Under the framework of the three-year agreement, Blancpain sponsored the original marine exploration activities in three sea areas. Up to now, the scientific research missions that have been successfully completed are: Pitcairn Islands Expedition and Saray Gomez Island Expedition. In addition, Blancpain strongly supports the famous French diver and marine biologist Laurent Ballesta and the Coelacanth Expedition Research Project; and has supported the first held in 2012 and 2014 respectively. And the Second World Ocean Summit.
Diving without respirator
Snorkeling: Floating on the water, divers face down to watch the underwater landscape through a mask, and at the same time, breathe out of the water through a short breathing tube.
Free diving: do not carry underwater air supply equipment, take a single breath and breathe before diving.
Diving with a respirator (scuba diving), the diver carries the gas used during water activities
Open scuba: The diver breathes from a compressed gas cylinder through a breathing regulator, and the exhaust gas is directly discharged into the water.
Closed loop respirator: The exhaust gas exhaled by the diver enters the recirculation, the system absorbs the carbon dioxide in it, re-injects the appropriate oxygen, and supplies it to the diver. This type of respirator does not produce any air bubbles.
Surface aspirated diving
In scuba diving, the volume of compressed gas cylinders limits the duration of underwater operations. In order to meet the needs of long-term underwater operations, an air supply pipe is used to deliver air from the surface to the diver for use. In addition to conveying air to the water, the umbilical cord also has functions such as temperature adjustment and power transmission.
Diving mask: keeps the diver’s eyesight in the water, but because there is a cavity in the mask, it is necessary to balance the air pressure through the exhaust of the nose (the mask drains).
Breathing tube: used on the surface to save air consumption in the cylinder.
Wetsuit: to maintain the body temperature of the diver and to a certain extent prevent injuries caused by accidental contact with aquatic animals and plants such as corals and jellyfish. Diving wetsuits are mainly used to keep warm, so there are different thicknesses and long and short sleeve styles to suit different diving environments. Generally, the thinnest is from 0.5mm to thicker 10mm. In tropical or subtropical diving, the more commonly used is 1-3mm. In cooler water temperatures, thicker 5mm or more wetsuits are required, while diving in colder water temperatures may require diving clothes.
Counterweight: Change the weight of the diver to help the diver sink into the water.
Fins: Provide divers with propulsion in the water (also can complete backwards and other actions).
Cylinder: stores compressed air for underwater use. The material is mostly stainless steel or aluminum, with different sizes and connection with switch system and breathing regulator.
Breathing regulator: The compressed air in the cylinder is adjusted to a pressure that humans can breathe.
Buoyancy adjustment device: The wearer’s buoyancy in water is controlled by the gas in the airbag.
Dive instrument cluster: usually includes a depth indicator and a cylinder pressure indicator.
Dive computer: Dive computers can usually indicate current depth, recommended safety stops, surface breaks, time to avoid flying, pressure levels, etc. The dive computer equipped with a wireless air pressure transmitter can also display the current air pressure in the cylinder in real time.
Dive watch: chronometer for diving. Must meet the following standards: unidirectional rotating time scale dial, the dial must have a minute scale, the time indicator can be recognized at 25 centimeters in complete darkness and the watch can still be in operation, shock and magnetic resistance, and adapt to various The temperature difference, the toughness of the strap, and the minimum depth of 100 meters.
Diving professional concept
Diving pressure: There are many cavities in the body, and the most obvious one is the lungs. When the body’s seawater pressure changes too quickly, or even exceeds the limits of the lungs, it may cause permanent lung damage. Generally speaking, it is recommended that the speed of ascent and descent should not exceed 18 m / min during diving.
Visibility in water: The visual range in water. Visibility is a term borrowed from atmospheric optics. Visibility in water is much lower than visibility in the atmosphere. Horizontal horizon in seawater is usually about one-thousandth of the horizon in the atmosphere. The main reason is that the attenuation and scattering of light in seawater is much stronger than in the atmosphere. The recognition of targets in water depends on the difference in radiance and color between the target and the background. As the observation distance increases, the difference in radiance between the target in the water and the background decreases rapidly, and the target becomes more blurred.
Safety stop: For safety, at the end of the dive, usually make a stop of more than 3 minutes at 5 meters. It is recommended to make a safety stop after each dive (if air supply and circumstances permit). When diving to a depth of 30 meters or more, or when the pressure level is within three pressure levels of the no-decompression limit, you must make a safe stop.
Surface dwell time: Surface dwell time is the time elapsed on the shore between two dives. At this time, the nitrogen dissolved in the body will still be released. The longer the water surface retention time, the less residual nitrogen in the body.
Bottom time: The time from when a diver enters the water to rises and leaves the surface, called the bottom time, the unit is minute.
