Have you ever worn a brand-new IP68 smart watch into a hot shower, only to find condensation under the screen afterward? Or worse—after swimming, the watch refuses to turn on.

The word "waterproof" sounds reassuring, but in reality, it hides many technical conditions and limitations.

In this article, BWOO explains what IP68 really means, clears up common misconceptions, and helps you understand when an IP68 smart watch is truly safe to wear—and when it is not.

1. Understanding IP68: What Does It Actually Mean?

What Is IP Rating?

IP stands for Ingress Protection, an international standard (IEC 60529) that defines how well an electronic device is protected against solid particles and liquids.

An IP rating consists of two numbers:

First Digit: "6" — Dust Protection

• Scale: 0–6

• 6 represents the highest dust protection level

• The device is completely sealed against dust and fine particles

Second Digit: "8" — Water Protection

• Scale: 0–9

• 8 means the device can withstand continuous immersion in water

• The depth and duration are defined by the manufacturer

A Critical Detail Most Users Miss

IP68 testing is conducted under controlled laboratory conditions:

• Room-temperature fresh water

• Static immersion

• No movement, no pressure changes, no chemicals

This is very different from real-life scenarios such as swimming, showering, or diving.

2. Core Product Highlight: A Truly Reliable IP68 Smart Watch — BWOO BO-WA10

IP68 Smart Watch with Fitness Tracker

Key Features: 

• Crystal-clear 1.43" HD touchscreen

• IP68 waterproof with multiple sports modes

• Track menstrual cycles and daily health metrics

• Up to 20 days of battery life on a single charge

Designed for daily wear and active lifestyles, BO-WA10 balances advanced protection with long-term durability, making it a dependable choice for fitness-focused users.

3. IP68 "Danger Zones": Situations You Should Avoid

1) Heat and Steam: Hot Showers & Saunas

Why it's risky:

Waterproof seals block liquid water, not microscopic water vapor.

High temperatures cause internal air expansion and accelerate seal aging, allowing moisture to penetrate.

Recommendation:

Avoid wearing your IP68 watch during hot showers, steam rooms, or saunas.

2) Salt & Chemicals: Seawater and Swimming Pools

Why it's risky:

• Salt is highly corrosive

• Chlorine and pool chemicals degrade rubber seals and adhesives over time

BWOO Advice:

If your BO-WA10 comes into contact with seawater or pool water, rinse it gently with fresh water and dry it thoroughly afterward.

3) Dynamic Water Pressure: Diving & High-Pressure Streams

Why it's risky:

IP68 is tested under static water pressure.

Jumping into water, diving, or rinsing under a strong tap creates sudden pressure far beyond lab conditions.

Bottom line:

IP68 does not equal protection against high-impact water force.

4. IP68 vs. 5ATM: What's the Real Difference?

5ATM (50 meters water resistance)

• Designed specifically for swimming and water sports

• Rated based on water pressure resistance

• Commonly used in professional swimming or diving watches

IP68

• Focuses on overall environmental protection

• More suitable for electronic devices with touchscreens, speakers, and sensors

BWOO Buying Insight

For most users who enjoy casual swimming, fitness training, and outdoor activities, the IP68 protection of the BWOO BO-WA10 is more than sufficient when used correctly.

5. Maintenance Tips: How to Extend Your Watch's Waterproof Life

• Check regularly: Look for cracks around the screen or loosened buttons

• Avoid impacts: Drops or strong shocks can cause micro-deformation and break the seal

• Dry before charging: Always ensure charging contacts are fully dry before connecting power

Proper care significantly extends waterproof performance over time.

Conclusion: IP68 Is Protection—Not a Superpower

IP68 provides a strong line of defense, but it is not absolute.

Understanding its limitations—and using your watch accordingly—is the key to long-term reliability.

With correct usage and thoughtful maintenance, the BWOO BO-WA10 delivers dependable performance for everyday wear, fitness tracking, and water exposure you can trust.
