How long can my Apple Watch stay underwater?

Apple Watches are water-resistant, not fully waterproof. Models Series 2 and later can theoretically stay underwater up to 50 metres deep for 30 minutes, but usage limitations apply. Always follow official guidelines and avoid high-velocity water or deep submersion.

Understanding Apple Watch Water Resistance

Apple uses water resistance ratings defined by the ISO 22810:2010 standard. It's essential to know the difference between water-resistant and waterproof. No Apple Watch is completely waterproof.

Series 2 and later models are rated water resistant to 50 metres, suitable for shallow-water activities. This is not intended for scuba diving or high-speed water sports.

Apple Watch Series and Water Resistance Ratings

Apple Watch Model	Water Resistance Level	Recommended Usage
Series 1	IPX7 (Splash resistant)	Handwashing only
Series 2–SE (1st Gen)	ISO 22810 / 50m	Swimming in pools
Series 7–Series 9	ISO 22810 & WR50	Shallow-water activities
Apple Watch Ultra	EN13319 up to 100m	Diving, high-pressure conditions

Can I shower with my Apple Watch?

Yes, but only if you're using Apple Watch Series 2 or later. Avoid soaps, shampoos, conditioners, lotions, and perfumes as they can degrade water seals. These substances can also cause skin irritation under the watch band.

Safe Shower Practices

• Use warm, not hot, water
• Rinse watch after showering
• Remove any soap residue

Is my Apple Watch waterproof?

No Apple Watch model is classified as waterproof. Water resistance decreases over time due to wear and tear. Apple advises against wearing the watch in saunas and steam rooms.

How Long Can I Swim with an Apple Watch?

Apple Watch models from Series 2 onwards are suitable for pool and shallow open water swimming. Apple Watch Ultra is designed for more intense water activities. Officially, these watches can withstand water up to 30 minutes at stated depths.

Practical Recommendations

Limit underwater exposure to 30 minutes to reduce seal weakening. Avoid prolonged water pressure or depth fluctuation. For extended activities, the Apple Watch straps designed for water use may offer more security.

Which Apple Watch Is Best for Underwater Use?

The Apple Watch Ultra is the most water-resistant model to date. It supports recreational scuba diving to depths of 40 metres. The Ultra also complies with dive computer standards (EN13319).

Ideal Water-Friendly Features

• Depth gauge
• Water temperature tracking
• High-pressure resistant body

Post-Swim Care for Your Apple Watch

It's important to rinse your watch with clean water after swimming. Salt and chlorine can corrode the casing and weaken seals. Gently dry the watch with a lint-free cloth immediately afterwards.

Protecting Accessories

Make sure your Apple Watch accessories are also compatible with water exposure. Leather and metal are not suitable for swimming. Opt for fluoroelastomer or silicone bands to ensure durability.

Factors That Can Reduce Water Resistance

Water resistance is not a permanent condition and may decrease. Daily wear can degrade the adhesive and seals. Impacts and high temperatures also contribute to reduced protection.

What to Avoid

Avoid exposing your Apple Watch to high-velocity water, such as jets from a hot tub. Also, don't press buttons while underwater. This can let water seep into the device.

Frequently Asked Questions (FAQ)

Can I dive with my Apple Watch?

Only the Apple Watch Ultra is designed for diving up to 40 metres. Other models are not suitable for high-pressure underwater activities.

What happens if water enters the watch?

Water entry usually indicates seal failure. Contact Apple Support immediately for diagnostics and potential repairs.

How do I expel water from the speaker?

Use the Water Lock feature in the Control Center. After your swim or shower, rotate the crown to eject trapped water from the speaker grills.

Does the Apple Watch track swimming automatically?

Yes, most newer models auto-detect swimming. You can also manually start a Swim workout to track laps and strokes.

Conclusion: How long can my Apple Watch stay underwater?

Apple Watch can stay underwater safely for up to 30 minutes at the rated depth: 50m for most models, 100m for Apple Watch Ultra. Prolonged or repeated underwater exposure, forceful water impact, and heat can compromise its integrity. Always follow Apple’s care guidelines for optimal performance and minimal risk.
