Can You Wear Your (Waterproof) Watch in the Shower?

Many people assume that a water-resistant watch is safe in the shower—but this is not the case. Even watches labeled “waterproof” may struggle with the heat and pressure of a shower.

Our answer? Usually, don’t shower with your watch on—with a few very specific exceptions.

Water Resistant ≠ Waterproof

In the watch world, there’s a big difference between:

• Water Resistant – tested in a lab under static, cool water pressure.

• Waterproof – often used loosely; still may not withstand hot, moving water.

• Diver’s Watch – built to stricter ISO standards and can handle higher pressure.

Why You Should Remove Your Watch Before Showering

Showering with your watch is like showering with your socks on—uncomfortable and unhygienic.

• Debris, oils, and skin cells can build up under the watch case and strap.

• Studies show skin under rings collects more germs than skin without. Watches are no different.

• Removing your watch protects it long-term and keeps it cleaner.

Understanding Water Resistance

Key points about water resistance:

• Static vs. Moving Water: Most watches are tested with still water. Showers create moving water, which increases pressure—often beyond the watch’s limit.

• Temperature Changes: Hot water causes metals to expand and contract, potentially allowing water to enter.

• Gaskets & Seals: Rubber seals wear over time. Soap, knocks, and moisture accelerate this. Regular servicing is essential.

• Glass & Scratches: Tiny scratches can compromise the watch’s seal. Sapphire crystal glass is more durable, but many watches still use plastic glass.

Diver’s Watches

High-quality dive watches are designed to handle pressure and temperature changes. However:

• Ensure the crown is screwed in properly.

• Never use push buttons underwater.

• Make sure the watch has been regularly serviced.

Older dive watches (pre-2010) may not meet the latest ISO 4625 standards.

Soap, Shampoo, and Chemicals

• Chemicals can damage rubber gaskets.

• If your watch comes into contact with soap or shampoo, rinse immediately with cool, fresh water.

Battery Replacement & Water Resistance

• Water resistance is not guaranteed after opening the back for battery replacement.

• Screw-back watches retain their seal better than snap-back watches.

• Pressure testing is recommended after any battery replacement.

When You Might Keep Your Watch On

There are a few situations where keeping your watch on is reasonable:

1. Safety concerns: At the beach, camping, or a public pool where you don’t want to leave your watch.

2. High-quality dive watches: Properly serviced watches built for water can handle showering, but always confirm with the manufacturer.

The Bottom Line

A watch is an investment. The safest option is to remove it before showering—it only takes a few seconds and protects your timepiece.

If you choose to shower with your watch on:

• Ensure it’s a high-quality, properly serviced watch.

• Understand that hot water, soap, and pressure can still cause damage.
