■OnePoint advice!
What you need to know about the natural enemy of watches is"Waterproof performance"It's about.
・What is the waterproof performance of your watch?
・I want to buy a waterproof watch, but where can I buy it safely?
I would appreciate it if you could use it as a reference in such a case (^^)
■Check the waterproof performance of your watch!
Even though it is called "waterproof performance", the function varies depending on the watch.
Let's check the functionality first.♪
Confirmation method ① Check from the back cover of the watch
The location varies depending on the watch, but inside the case back. "BAR"Ya"ATM" , or "meter" "feet"It is written as .
According to JIS (Japanese Industrial Standards), it is as follows.
・Daily life waterproofing = “BAR” or “ATM” (atmospheric pressure) display
・Diving watch = "meter" or "feet" display
*The following watches have "10BAR", so they have a waterproof performance of "10 ATM".
Confirmation method ② Confirm from our product page
At our store, we list the waterproof performance of each watch.
You can also check this information.
・Waterproof for daily life
・Reinforced waterproof for daily life
・Waterproof for diving, etc.
There are various notations.
*The following watches are "water resistant for everyday use (5 atm)".
■What is the difference between waterproof function?
That① “Waterproof for everyday life”
・Inscription on camera back: “WATER RESIST” or “W.R”
・Nanaple notation: "Waterproof for everyday life" or "Waterproof for everyday life (5 atm)"
It is said to be able to withstand sweat from everyday life, water droplets from washing your face, rain, etc.It has minimal waterproof performance and cannot be used for water work, water sports, skin diving, or diving.
Most are up to 5 atm (5ATM, 5BAR),We recommend that you be careful when using water as it does not have waterproof performance!
Part 2: “Reinforced waterproofing for daily life”
・Notation on camera back: “10BAR” or “20BAR”
・Nanaple notation: "Reinforced waterproof for daily life"
According to JIS standards and IOS standards (International Organization for Standardization),It can be used around water, including the ocean and pools, up to and including free diving.
However, it is not a diving watch or diver watch, so please be careful not to use it excessively.
Part 3: “Waterproof for diving”
・Notation on camera back: "DIVER'S100-200M", "AIR DIVER'S 100-200M", etc.
・Nanaple notation: "Waterproof for 〇〇m diving"
It is called an air diving watch, and is pressure resistant at the indicated depth and waterproof enough to withstand long periods of underwater use.
Equipped with equipment such as a rotating bezel necessary to measure diving time and decompression time.A watch that can be used when diving in shallow water (scuba diving, etc.) with compressed air breathing gas in a cylinder.It is.
Some people may think that the water resistance is the same as daily life waterproofing of 10 to 20 atmospheres, but since this is a diver's watch that can be used for diving, it is actually designed to withstand water pressure 25% higher than the displayed value.The crown and case back are also designed to be screwed in to prevent water from entering, making it even more resistant to water!
Part 4: “Waterproof for saturation diving”
・Notation on camera back: "DIVER'S200~1000M", "He-GAS DIVER'S 200~1000M", etc.
・Nanaple notation: “Waterproof for 〇〇m saturation diving”
It is called a saturation diving watch and is waterproof enough to withstand diving to the indicated depth.
Equipped with equipment such as a rotating bezel necessary to measure diving time and decompression time.A watch that uses breathing gas of a mixture of helium and oxygen and can be used when diving in the deep sea (saturation diving).It is.
If you've come this far, you're a waterproofing expert! As long as you use it correctly, you won't have to worry about it getting flooded.
I want a watch that is water resistant! If that's the case, we recommend purchasing one with this class of waterproof performance!
■Important knowledge about diving watches
This description is based on the JIS standard.
In most cases, there is no problem if you use it as described, but in reality, there are many watches that do not strictly adhere to this standard, and some are labeled as 100M or 200M even though they are not divers.
Therefore,When using it underwater, we strongly recommend that you carefully check the included instructions before use!
These waterproof diving watches are waterproof enough to withstand all types of underwater use within the indicated depth.
Of course, this does not apply if you make an incorrect button or crown operation underwater, but if you are considering using it underwater, you can rest assured by choosing this (^^)
■Finally
There are many differences in waterproof performance depending on the watch, so it may be confusing.
However, if you understand that it is chicken, you can use it with more peace of mind!
If you have any questions or concerns, please feel free to contact our store.♪
I think it's often used for leisure, especially in the summer, so I hope it's helpful in some way (^^)
