It's an unknown world.

世界初(※)、光発電による飽和潜水1,000メートル防水を実現した腕時計「プロマスター エコ・ドライブ プロフェッショナルダイバー1000m」が、2017年7月にシチズン時計株式会社から発売になります。(※1,000m飽和潜水用防水の光発電時計として。2017年5月シチズン調べ。)

When saturated diving is 1000 meters waterproof, in order to pass the waterproof test stipulated by JIS, it must withstand the unimaginable pressure of "125barometric pressure" in the deep sea. When it comes to 125 pressure, it takes a force of 125 kilometers per square centimeter. Obviously, the durability and waterproofing of tons of Monay are required.

Moreover, the sale of "professional master eco-driven professional diver 1000m", in the 1000-meter waterproof level equipped with the world's first "photopower", fully rechargeable for 1.5 years. There is no need to replace the battery regularly, this is a watch suitable for professional specifications.

However, there is only one simple question. Although we know that saturation diving is very waterproof for 1000 meters, can one dive that deep?

A challenge that mankind will never get tired of. The unknown "saturation diving" world

What is "saturation diving"? For such people, learn a little here.

A technique called "saturation diving" is needed when people expose their bodies to the deep sea for diving. Unlike air diving (such as diving) from the surface to the sea, saturated divers absorb a mixture of oxygen and helium in a high-pressure environment, leaving the body in a "pressurized state" that can withstand deep water pressure before diving into the sea.

As a step, first the diver enters the pressurized ground water tank (about 4 tatami living space) to adapt the body to the high-pressure environment. Then under pressure, move to the capsule at the same pressure as the tank, and each capsule descends to the deep sea. After reaching the deep sea, open the hatch and work from there to the deep sea.

A pressurized diver cannot go out immediately (atmospheric pressure) just because the deep-sea operation is over. After diving, the diver must return to the fuel tank in the high-pressure environment through the capsule, so that the body can "decompress" to a normal state. As a result, in some cases, they sometimes live in tanks for more than a few weeks. People with claustrophobia may be a little impossible.

Now, in terms of how deep a person can dive, divers of the Maritime self-Defense Force successfully "saturated dive 450 meters" in 2008, which is the second largest record in the world. In other words, the number of saturation diving of 1000 meters is itself an unknown world, just like human romance. (by the way, the first place is 701 meters in the simulation experiment on the ground.)

Even for such SDF personnel, 450 meters have finally reached the deep sea, and even civilians have had the experience of "saturation diving for 300 meters." This is Yasuchi Noguchi in this interview.

Noguchi is the only private company in Japan to adopt saturated diving system, which is responsible for the development and management of saturated diving system. Now, we are using the experience of saturated divers to support divers on land.

This time we asked such Mr. Noguchi about the "saturation diving job" that ordinary people are not familiar with, and about the "world at a depth of 300 meters" experienced by Mr. Noguchi.

There are only about 50 people in Japan. What is the job of a "saturated diver" active in the world's oceans?

──「飽和潜水」とは、どういうお仕事なんですか?

Without a specific job, when there is a job in the sea where it is impossible to dive from the surface, it is the turn of "saturation diving".

For example, there is also the work of recovering objects at a depth of 100 meters, as well as lifting boats and carrying out rescue operations in the deep sea. Not only in the seaside, in places like dams, not only in very deep places, but also when the water depth is about 15 meters.

──そういう浅いところの場合、飽和潜水士を使うメリットというのは?

The best thing is quality. Even where you can dive from the surface, the longer the construction period, the longer the same divers will be able to work long hours, so the more benefits of using saturation diving in terms of quality. You may be surprised that working on air diving (helmet diving) requires more divers than saturation diving.

──飽和潜水士は、日本にどのくらいいるのでしょうか。

Although we don't know the detailed number, there are about 30 people in our company and about 50 people in the whole country.

──飽和潜水士になるための学校があるとか?

There are schools abroad, but there are no schools at home. Everyone educates from scratch in the company. It takes at least 3 years to work as a saturated diver and to pursue further studies. Because my family is the only one who goes saturation diving in the folk. Next up is Mr. self-Defense Forces.

──飽和潜水士という仕事の魅力とは?

Because not everyone can do the work, so the first is the sense of achievement when the task is completed. And, to tell you the truth, the "special allowance" that you get separately from your salary is also one of the drivers. Well, it's hard to sustain without such benefits. Which means putting yourself in danger.

──海外では高収入という面からも、飽和潜水士が人気職種というのを聞いたことがあります。

It is said that there are also many free divers who "dive for only half a year and then close down for the remaining half a year". There may be very few such people in Japan.

──特別ボーナスがあるにしても、かなり過酷そうな仕事ですね。

Because it is a profession in the water, it is said that there are many divers with bad ears. And saturated divers will continue to be exposed to abnormal air pressure, so even if there is no change in appearance, it is still hard work.

What is the body screaming field of "300 meters deep" in the world?

──野口さんは、もともと海洋研究開発機構(JAMSTEC)で飽和潜水の訓練を受けていたとお聞きしました。

From 18 to 26 years old, he received education and training on saturation diving in JAMSTEC. In addition to 60, 100 and 200 meters, we also experienced a deep sea of up to 300 meters.

──300メートルとなると、身体を加圧するだけでも大変そうですね。

According to the records at that time, the compression took more than half a day. I think there is a personal difference in pressurization. My situation is that from more than 200 meters or so, I have a very serious memory of joint pain. The field of vision also narrows after compression, so I hit my head on the bed many times.

──そういう環境に何日も身を置くわけですが、怖さは感じませんでしたか?

もはやSFレベルのスペック。飽和潜水1,000メートル防水の時計はどれだけスゴいか「深海の仕事」のプロに聞いてみた

Well, I'm so selfless. My words take about two days to get used to, but everyone is used to symptoms for different days. Our company has reached the "saturation diving of 200 meters", so this kind of symptom will hardly occur.

──200メートルと300メートルでは、体にかかる負担が全然違う?

From my experience, it's completely different. Does that mean the body will scream from more than 200? Breathing can be done normally, but it is the feeling of inhaling sticky gas.

──深海300メートルってどんな世界なんですか?

Because it is a world completely out of reach of the sun, it is dark and the water temperature is quite low. According to the different seasons, because it is below 10 degrees, it is too cold to work if you don't put warm water in your suit.

──初めて深海に降り立ったときの心境は?

At the moment of the capsule, the sea floor is full of "jade crabs".... no, no, no.

──カニ、ですか?

Anyway, it's shocking. Hairy crabs are crabs that only live in the deep sea, so it is generally difficult to see. So, I saw the hairy crabs in a mess and said, "Oh, have I finally come to such a deep sea?" (laughter).

──カニを見て実感したと(笑)。

I think there are many deep-sea fish, but I am too impressed with the crabs (laughter). Well, if you don't shine the light, you can't see anything, so 200 and 300 won't change if you go to the sea. That's what I mean.

An enclosed space isolated from the outside world. Life in the world's wonderful "high-pressure environment"

──飽和潜水では身体を“加圧状態”にするわけですが、人は何日くらいまで加圧状態で生活できるのですか?

Although we do not know the medical situation, according to the regulations of our company, the continuous working time of a diver, plus the time of compression and decompression, is up to 28 days. If it takes 4 days to decompress and decompress, 24 days. You can work for 18 days if you have 10 days. During the period of pressure and decompression, it will also change with the water depth.

──作業期間中はもちろん、減圧期間もずっとタンク内で生活を続けるわけですよね。

Right. Live in the fuel tank until the body decompresses pressure. Lie in bed and have a snack. There is no TV, but the small game console is brought in by OK.

In addition, muscle exercise in tanks is prohibited because of the high risk of decompression sickness. Drinking and smoking are also prohibited. Although meals are paid for from the outside, raw things such as sashimi may have a bad stomach, so I can't. It's no good to catch fresh fish around.

──スマホやネットは使えないのですか?

It's basically forbidden. Because, this is to prevent divers from receiving messages from the outside. If something bad happens to your family, you can't go out unless you decompress your body. From the point of view of protecting the spirit of the diver, it is also the state of deliberately cutting off the outside information.

There's no phone in the tank. Only those who direct diving operations from the outside can be contacted. No matter how much you want to get out, you can't open the hatch until you decompress. Because it's a matter of life.

──もしタンクのハッチをいきなり開けたら…。

I'm afraid he died on the spot. However, I have never seen such a scene, so I am not very clear, but it is probably a blood vessel flying out, or ruptured.

──な、なるほど…。ちなみに、タンク内での生活で困ったことや不便なことってありましたか?

Although there is no particular change in appearance, because the pressure in the tank uses a mixture of oxygen and helium, the higher the pressure, the more helium in the air. as a result, the diver's voice becomes shrill during the pressure.

──声が高くなるんですね。

It is also known as the helium sound, and the deeper the water, the louder the sound. In deep places, even the divers inside are difficult to talk to each other.

──他に、普段の生活と違うところってありましたか?

Under high pressure, "things with bubbles" and "things without holes" will deform. For example, the container of the cup noodle is full of bubbles, and when pressurized, only the container shrinks, and the contents fly out of the outside.

When I dived for 300 meters, I also ate ice cream inside. Under pressure, it is compressed to less than half the size, but accordingly, the taste becomes strong and delicious (laughter).

──(笑)

Because ice cream will be smoother and finer without bubbles. The ice cream eaten in the deep sea is very delicious (laughter).

Wearing a "saturated diving 1000 meters waterproof" watch, want to challenge the deep sea 1000 meters?

──飽和潜水士たちは、場合によっては数週間以上もタンク内で生活するわけですが、生活リズムを維持するだけでも大変そうですね。

With regard to the diver's schedule, people outside are managed from wake-up time to bedtime, so the pace of life will not be disrupted. However, because the divers inside lost the sense of time and week, they made a mark on the calendar to grasp "what day it is today".

──作業にはやはり腕時計が欠かせない?

Saturated divers follow instructions from the outside, so they rarely look at their watches to judge anything. However, in the fuel tank, you still care about time.

──飽和潜水士の方には、どういう時計が人気なのでしょうか。

Saturation diving is really very popular. If it is an ordinary diagonal rod, there will be "helium" inside, and the watch will break down during decompression. Because you don't have to worry about that for saturation diving. Besides, this watch is photoelectricity, isn't it?

──そうなんです。世界初、飽和潜水1,000メートル対応で光発電。フル充電で1年半くらいは余裕で動きます。

It's better there. It is difficult for saturated divers to go out once they start their homework. This watch can make Bessel Locke, and the hands are thick and easy to read. I also like this tenacious design.

──ちなみに、「プロマスター エコ・ドライブ プロフェッショナルダイバー1000m」は飽和潜水1,000メートル防水です。もしチャンスがあるなら、その時計を持って1,000メートルの深海に行ってみたいですか?

No, I don't want to go at all (laugh).

──あ、そうなんですね。

Because under the pressure of 1000 meters, I can no longer imagine how much the body will change. Say before human romance: "Ah, it looks painful." So, I definitely don't want to go (laugh). Ah, isn't that a good answer?

──いえ、それこそ正直なご意見だと思います(笑)。

However, although not a follow-up, but saturated diving 1000 meters waterproof, as a watch technology is still very powerful. In fact, the simulation on the ground can reach 701 meters. Sure enough, as a human dream, we must first have a watch that can withstand 1000 meters.

Man's unexplored saturation diving of 1000 meters. Nevertheless, why does West Railway City want to be a "professional master ecological driving professional diver 1000 meters"?

As Mr. Noguchi also pointed out in an interview, helium invades the watch during saturation diving, which may damage the watch for its reasons.

Helium atoms are small enough to penetrate plastic, so to achieve a saturated diving 1000-meter compatible watch requires not only waterproof to withstand 1000 meters of water pressure, but also "overwhelming airtightness" to prevent helium from invading under high pressure.

"professional master environmental protection driving professional diver 1000m" in pursuit of its high air tightness, skilled craftsmen have manually completed all the assembly of glass and shell. As a result, only 35 can be produced in a day. A thorough attention has been paid to the details.

But why does West Rail City need to do this and make watches with "saturated diving of 1000 meters"?

The answer is the key message "GO BEYOND (imagined Future)" put forward by the "West Railway City expert". By creating clocks that exceed the limits of human beings, we can stimulate people's imagination and cheer for people's aspirations and dreams of unknown territory. This is what West Rail City is really trying to convey.

In order to achieve this goal, West Rail City provides support for the two Japanese sea exploration teams "Team KUROSHIO" and the lunar exploration team "HAKUTO", which challenge the world-class competition "XPRIZE". 7Accord 15 will also be interviewed by Team KUROSHIO members on GINZA SIX. Please see Cochilla for details.

I want to go a little beyond my limits. I want to challenge uncharted territory. Although professional masters stimulate your existence, they are also the strongest partners who do not succumb to any cruel situation.

It's not just the sea! Master for professionals who want to challenge on land and air is also available at the same time.

The professional masters of West Railway City not only launched the "sea", but also launched professional watches to challenge the "land" and "empty" venues.

Equipped with cutting-edge technology, the outdoor watch "Eco-driven Alticorn" is an exquisite model that simulates the height and azimuth information "from 10000m to-300m above sea level", exceeding the height of all the mountains on earth. Outdoor sports are of course easier to cater to business scenes. Elegant design is very popular.

In addition, the global limited edition of 700 "eco-driven GPS satellite radio clock F900" is the most advanced model of the professional master SKY series. Equipped with dual-time and timing functions, it can receive GPS satellite radio waves in the fastest and shortest 3 seconds in the world. Complete the gorgeous design by turning the box into gold.

West Rail City professional master series that inspire human curiosity. Climb mountains, dive into the sea, fly in the sky-which field do you want to challenge?
