5ATM vs 10ATM Waterproof Smartwatch: Which One Is Enough for Your Needs?

A 10ATM waterproof smartwatch is the necessary choice for people doing water sports in the ocean. Most users only need a 5ATM rating for basic activities like swimming in a pool or taking a cold shower.

You should buy a 10ATM watch when you need maximum protection for activities like snorkeling or surfing. The right choice sports watch depends on the amount of water pressure the device will face in the water.

Defining the Basics: What Does a 10ATM Waterproof Rating Mean?

A 10ATM rating means the watch passed the ISO 22810 international standard for water resistance. This test places the watch in a machine that applies 10 bars of pressure to the case.

This amount of pressure is equal to being 100 meters deep in completely still water. Manufacturers use this standard to prove the watch remains sealed under heavy weight.

Real movement in the water creates extra force called dynamic pressure. When a swimmer moves their arm fast, the water hits the watch seals with more power than the static test suggests.

This extra force can push water inside a watch that has a lower rating. A 10ATM rating provides a high safety margin to handle these sudden changes in pressure during sports.

The Practical Limits of 5ATM in Everyday Water Activities

A 5ATM rating means the watch can withstand 5 kilograms of pressure on every square centimeter of its surface. This 5 bar limit is the standard for watches made for low impact water use. The internal seals stop leaks during slow movements in shallow water. Most lifestyle watches use this rating to balance protection with a thin design.

The seals on a 5ATM watch cannot handle the high pressure from water jets or fast surface impacts. This rating allows you to swim slowly in a pool or wash your hands without damage. You must avoid activities where water moves quickly against the watch. High pressure from a shower head or a fast water slide can exceed the 5 bar limit and cause a leak.

The choice between these two ratings depends on the speed and pressure of the water. This table helps you decide which level of protection matches your lifestyle.

KOSPET Recommendations: Choosing Between 5ATM and 10ATM Models

KOSPET separates its product line into two categories for different water environments. The new TANK T4 and M4 series feature a 10ATM rating for diving and high speed water sports. The TANK M3 Ultra and T3 Ultra 2 series utilize a 5ATM rating for hiking and surface swimming. You should select the model that fits your specific activity level.

How to Maintain the Water Seals of Your Smartwatch

Proper care keeps the waterproof seals of a watch in good condition for many years. Salt from the ocean can damage the rubber gaskets and cause leaks over time. You must rinse the watch with fresh water after every trip to the beach to remove salt and sand. This simple habit prevents the seals from drying out or losing their grip.

You must also keep the watch away from hot steam in the shower or sauna. Heat makes the waterproof seals change shape and fail to keep water out. Soap and shampoo can also weaken the chemical bonds of the waterproof glue over time. Taking care of the hardware ensures the watch remains waterproof for every future activity.

Is 10ATM Worth the Upgrade?

The upgrade to a 10ATM watch is a smart investment for active outdoor people. A 10ATM watch provides the highest level of durability for the TANK series. It removes the worry of water damage during any activity. This rating provides total peace of mind in every environment.

People who stay on land or in pools can save money with a 5ATM model like the TANK M3 Ultra. People who love the ocean should choose the 10ATM TANK M4 for total protection. The extra cost of a 10ATM watch is small compared to the cost of replacing a broken device. Choosing the stronger watch is always the better plan for long term use.

FAQs

Can I wear my 5ATM or 10ATM smartwatch in a hot shower?

You must not wear any smartwatch in a hot shower or sauna. The heat from the steam causes the rubber seals to expand and change shape. This expansion creates tiny gaps that allow water to enter and destroy the internal electronics.

Is a 5ATM rating enough for swimming in the ocean?

A 5ATM rating is not strong enough for ocean swimming. The dynamic pressure from waves and currents often exceeds the limit of a 5ATM device. You should use a 10ATM watch to ensure safety during open water activities.

Do I need to clean my waterproof watch after swimming?

You must clean your watch with fresh water after every swim. Salt water and pool chemicals corrode the waterproof gaskets over time. Rinsing the device removes these harmful elements and keeps the seals functional.
