Every summer, facing the fiery and hot environment of the sun, everyone is eager for a cold beer, a pleasant evening breeze, a wide ocean, and enjoy the coolness and excitement of the heart and spleen. The diving watch is definitely one of the cool products that has attracted much attention this summer. Although not everyone is interested and masters diving skills, every man has a deep desire for diving watches. So how much do you know about diving watches? Then let the watch house take you to understand the tone of the diving watch.
Five performances of diving watches
The so-called diving watch, as the name implies, refers to a watch that is water-resistant and used for diving. General waterproof watches can not be used for diving, diving watches must meet strict regulations, not waterproof enough to be called a diving watch. Generally, it cannot be operated underwater, and some are better able to operate underwater.
‘Exhaust helium’ can be said to be a very professional function, it is usually used for professional diving watches (waterproof more than 1000m). Because full-time divers cannot travel to and from the sea every time they work in the deep sea, this wastes too much time decompressing. Therefore, they must live in a high-pressure diving tank in the deep sea for a long time, but at this time, a considerable amount of gas will be dissolved in the blood, so the air used in the diving tank is generally a helium-oxygen mixture. And because helium molecules are smaller than water molecules, when we are under high pressure for a long time, the helium molecules will infiltrate the waterproof watch and fill it with high-pressure helium. Once it returns to the water surface, the high-pressure helium in the watch cannot be shorter. When the time runs out, the watch will explode due to high voltage.
Under the dark and helpless water, we will strongly appreciate the yearning for light. As the basis for reading underwater, all diving watches will be equipped with eye-catching luminous hands and scales. Usually the hands, scales or surfaces of diving watches are coated with fluorescent materials, and the dimensions of the hands and scales are deliberately enlarged to make it easier for divers to read. The early luminous material was radium, which was discontinued because it contained excessive radioactive elements. The most commonly used luminous material is Super-LumiNova. It absorbs the gamma particles in the light to store light and can continue to emit light for more than 10 hours (but the intensity of the light emission will have an attenuation effect after a certain period).
The rotating bezel is mainly to remind the diver of the diving time. The scale of the rotating bezel is generally 15, 30, 45. This is because oxygen cylinders for diving can only last for 45 minutes (some are marked with a 60-minute scale). The first 15 minutes are colored or specially marked. Generally, just turn the bezel during the dive, make the 0 scale on the bezel align with the minute hand, and then watch the scale on the bezel after the minute hand moves to know the time spent diving.
Of course, you can also count down. First of all, know your dive time. Turn the bezel to align the minute scale with the minute hand, and then the time when the minute hand reaches the 0 scale of the bezel is your diving limit time. The rotation of the external bezel is mostly designed in a single counterclockwise direction. This is to ensure that the calculation time is only accounted for more, not accounted for, and to prevent delays and danger. In recent years, the emerging built-in chronograph bezel has no restriction on the direction of rotation, because the crown that controls the bezel must be locked before launching.
Screw-down non-slip crown
Where is the most susceptible part of a watch to water? The answer is definitely the crown, because the crown is the only part that connects the outside world with the movement. In order to prevent water from entering the movement through the crown, watchmakers have developed a design called a screw-in crown—the joint of the crown is added with a waterproof rubber ring made of rubber. When the crown is tightened, , The water is tightly isolated from the watch (similar to the rubber pad at the water pipe valve in our home). There are also many diving watches that have been upgraded. Not only do they have larger crowns, but they also add deeper pits to them, making them more slippery and convenient for underwater operations.
Anti-corrosive flexible strap
Under the water, no matter whether we move our arms or operate the instrument, we need to flex our wrists flexibly. At this time, the watch needs to be closely fitted and fixed on the wrist. Although many diving watches are equipped with metal straps, the chemical composition in the seawater will cause slight corrosion, so it is still recommended to replace with rubber straps with better water resistance and corrosion resistance during diving. Some brands now also develop A canvas or rayon strap is also a good choice.
Since its introduction in 1953, Blancpain’s Fifty Fathoms series has been a classic choice for modern divers. Fifty’s unique many technical features and product characteristics have steadily established its pioneer position in the diving watch industry, with many leading advantages such as safety, reliability, ruggedness, readability, anti-magnetic and aesthetics. , Making its achievements in the industry still impressive. The Fifty Fathoms series is sturdy and reliable, with a modern style. The design reflects sports style and is full of masculinity. Equipped with a unidirectional rotating bezel, it also retains the design features of the original Bathyscaphe style. The crystal shining punctuation ensures the readability of diving timing information in any environment. At the same time, the device can display the dive time on the dial to remind the diver when to go up. The numbers and hands are usually paired with a dark dial, which is legible even at night.
The watch is equipped with Blancpain’s remarkable Cal. 1315 movement, which is reliable, tough and durable. It is powered by a mechanical automatic winding movement with a frequency of 28,800 / hour. The Blancpain watchmaker, who has always focused on creating the perfect movement, uses a silicon hairspring to enhance the accuracy of the movement. The sapphire crystal caseback can be used to see it.
