Shulou(Shulou.com)11/24 Report--

Just last week, Apple unveiled an oversized watch called Apple Watch Ultra, which focuses on professional sports and extreme outdoor scenes.

The watch is also the first Ultra version of Apple's smartwatch. Unlike the flagship series, the Apple Watch Ultra's extreme mode can last up to 60 hours to meet the needs of sports professionals.

Talking about the product, senior diver Haje Jan Kamps said: "I am willing to entrust my life to Apple Watch Ultra."

So, from a professional diver's point of view, what about Apple Watch Ultra? What can it do in this scene? We're trying to find the answer.

01. Aimed at the largest diving scene, Apple Watch Ultra is more general-purpose than professional equipment and is specially designed for leisure scuba diving at a depth of about 40 meters, and less than 30 meters is where diving occurs most frequently.

Oceanic + will record the visibility, current and other diving records that divers are most concerned about during diving. In addition, the app will remind divers at appropriate times not to stay too deep for too long, and warn them when they surface too quickly, and these two functions are also two important aspects of people's safety during diving.

As a professional diver, Haje Jan Kamps said: "I look forward to diving with a smartwatch with a digital crown." Because, at present, most of the recording equipment used by divers are bulky, and when they put on diving gloves, it will be more difficult to operate.

Compared with high-end diving recording equipment, the advantage of Apple Watch Ultra is that it is not designed for diving, so its general function is more powerful.

However, under water, the watch will lose its signal, but when people return to the surface, these functions can be used normally, which is not provided by ordinary diving watches.

02. Incorrect diving methods may be life-threatening. Why is a diving watch so important? Let's start with the dangers that people may encounter when diving.

Have you ever heard of diving decompression sickness? Generally speaking, when you stay underwater for a certain period of time, when you return to the surface, the pressure changes so rapidly that the gas dissolved in the body does not have time to be excreted with breathing, and bubbles are formed in the tissue and blood. When decompression sickness is serious, it can lead to hemiplegia, coma, and even life-threatening.

Previously, such diseases usually occurred in people working in caves, astronauts and so on, but now these symptoms are often seen in diving activities.

More intuitively, we breathe about 78% of nitrogen, 21% of oxygen and 1% of other gases. But when you breathe pure oxygen at the bottom of the sea, it becomes toxic and can even cause seizures.

Therefore, in order to ensure that humans stay underwater for a long time, divers will carry compressed air, which usually contains 78% to 65% nitrogen, which is then converted into gas that the human lungs can breathe directly to ensure the normal movement of people in the water.

This gas is also the "culprit" that leads to the risk of decompression sickness in divers.

Just like soda, when you tighten the bottle cap, you don't see obvious bubbles in the bottle, but when you shake the bottle violently and open it again, there will be a lot of liquid ejected. Similarly, there is gas in your blood, and it doesn't matter when you are still, but when you swim quickly from the deep sea to the surface, the bubbles in your blood will pop up quickly.

A diving watch monitors the amount of nitrogen in your body and warns people when they surface too quickly or stay in the deep sea for a long time to keep people safe.

03. Cooperate with well-known diving manufacturers to give a timely warning of nitrogen content in the body. Specifically, when you are diving, a smartwatch can do several things: use pressure gauges and clocks to record your stay at a specific depth while diving. Some devices will record every 10 seconds, some 30 seconds, this recording frequency is not critical, more importantly, it can help you record.

Normally, a smartwatch will record you staying at a depth of 10 meters for 20 minutes, and then help you calculate the duration of your next dive. At best, smartwatches for diving can keep detailed records of different depths, but so far, many diving watches are not perfect.

Therefore, for the sake of conservatism, divers can only reduce the frequency of diving and spend a lot of time sitting on diving boats waiting for nitrogen to be discharged, which is not the best solution to this problem.

Haje Jan Kamps believes that a better way is to improve smartwatches.

Many people will think that Apple's smartwatch can't do it either, but Haje Jan Kamps said: "Apple's smartwatch is already very good at recording steps, heart rate, exercise and so on."

However, these recording functions are not the key, and the top priority of the problem is the algorithm for calculating the amount of nitrogen in the human body.

The difficulty is that the accuracy of recording is affected because people have different body structures and different tissues absorb and release nitrogen quickly and slowly.

Therefore, it is very difficult for Apple to design its own diving algorithm. Apple has partnered with Oceanic, a well-known diving equipment company, to develop an app called Oceanic+, that displays divers' diving depth, launching time and water temperature, and uses B ü hlmann's algorithm to determine how nitrogen changes in the human body.

04. Conclusion: recognized by professionals, Apple Watch Ultra, as one of the most important new products in this conference, is designed for high-risk, high-intensity professional sports personnel. this is the first time that Apple has added an Ultra version to the Apple Watch product line.

Before the product is officially shipped, it has been recognized by divers in professional sports scenes, and its performance and design have maintained Apple's consistent style, coupled with the linkage with devices such as iPhone. May make professionals more inclined to buy.

When consumers do get Apple Watch Ultra, it may trigger a new round of discussion about the product.
