Diving Watch 's Inner and Outer Rings Introduction

Divers like to carry a small amount of oxygen tanks. In order to reduce the weight of the water, but the amount of oxygen is related to the size of the oxygen cylinder, people familiar with diving equipment will have a device to measure the amount of oxygen.

The diving watch strengthens this need in a timely manner. . The rotating outer ring can be said to be the biggest feature of the diving watch, which plays a role in reminding the diving time. The rotating bezel has a marking scale of 15, 30, 45, because the oxygen cylinders for general diving can only be held for 45 minutes, and some are marked with a 60-minute scale. The first 15 minutes are coloured or specially marked, as the diver will strictly follow the 15 minute safety stop when rising to completely release the nitrogen absorbed from the cylinder. Usually, as long as you turn the bezel while diving, align the 0 mark on the bezel with the minute hand, and then look at the scale on the bezel after the minute hand moves to know the time spent on the dive. Of course, you can also use the countdown. First, know your dive time. Turn the bezel to align the minute mark with the minute hand. Then the minute hand goes to the 0 mark. It is just your dive time. That is to say, the 0 mark position is your dive. Limit time.

The rotation of the external bezel is designed to be a single counterclockwise direction. This is to ensure that the calculation time is only accounted for more, less accounting, and preventing misoperations from extending the time. Professional fluorescent coatings on both scales and numbers make it easy to display clearly when the underwater light is dim. In recent years, the emerging built-in chronograph bezel has no rotation direction limitation, because the crown of the control bezel must be locked before entering the water. For example, the Aquatimer Cousteau in the United States, the built-in chronograph bezel can guarantee the prompt function, without the need to open another hole in the case. Another benefit is that there is no need to clean the sand in the seams of the bezel case after the water is discharged. In fact, only 1000 people who buy diving watches may have 5 chances to sneak into the depth of 50 meters. Compared with the nominal number, more players love the crisp answer when rotating the bezel. Omega's Ploprof coaxial dive watch rotating outer ring is controlled by the orange button attached to the upper right side of the case, which can be rotated clockwise or counterclockwise. The design of the outer ring of the dive watch can be rotated in both directions. There are actually no crafts on the bezel, but Blancpain's 50-series single-rotor bezel is different. The designer used sapphire crystal to cover the fluorescent scale (not the ordinary high-tech ceramics), and spent several years developing a glue that binds the fluorescent scale material to the sapphire bezel and metal bezel. And applied for a patent. Rolex uses patented PVD technology to fill the rotating bezel with platinum. Thanks to a new illuminating material that emits blue light, the triangular zero on the outer ring of the scale indicates longer visible time at night or in the deep sea.

All dive watches are equipped with eye-catching luminous hands and scales, because divers are often in the dark deep sea, so the hands, scales or surfaces of the dive watch are usually coated with fluorescent material and deliberately enlarge the size of the hands and scales. In order to make it easier for users to read the time.

The early luminous material was Radium, which was discontinued due to its excessive emission. The most commonly used luminous materials are Super-LumiNova and helium gas tubes. Super-LumiNova is a new material that absorbs gamma particles in the light and stores it for more than 10 hours, but the intensity of the luminescence will decay after a certain period of time. It’s a big leap in modern night light technology, even though it’s called “gas light”. The use of the helium tube is a glorious tradition of Ball. The advantage is that self-illumination not only has high brightness, but also has a long life - it is said that the service life can be as long as 25 years. The principle is that a mineral glass tube coated with a phosphor on the inner wall is filled with a gaseous ruthenium, and a B-ray of yttrium is used to excite the phosphor to react to generate a cold light source, which has no dazzling light and heat, and does not burn or explode. The wall of the tube can be isolated from B rays, as long as the tube is not broken and is harmless to humans. The helium tube does not require external energy supply or external light source reflection, and can maintain stable and long-lasting illumination for 10 to 20 years. The nightlights on the back cover of the watch case are marked with 3H illumination and mbmicrotec letters. On all the pointers and scales of Boll's watches, there are tube nights (including temperature and second hand). The only bad thing about this is that the hands will be heavy, especially the second hand. This should have a slight effect on the watch. In order to maintain balance, the second hand of the Boll watch has a "long tail" or two RRs. "Flower tail". The facelight effect of the Panerai Radiomir is achieved by applying a special coating on the markings and indicators, which is a mixture of zinc sulfide, radium bromide and neodymium. This compound, invented and formulated by Panerai, was previously a feature of sighting and observation instruments produced by Florentine. The powerful illuminating effect allows the instrument to illuminate itself in a completely dark environment without the need to borrow auxiliary lighting that may be found by the enemy.
