You’re standing at the edge of the pool. Maybe you're at the beach, feeling the salt spray. You look down at that expensive piece of glass and aluminum on your wrist and wonder: can Apple Watches get wet without turning into a very pricey paperweight?
Most people think "water-resistant" means "waterproof." It doesn't. Not even close. If you treat your Apple Watch like it’s a submarine, you’re going to have a bad time. Honestly, the marketing can be a bit misleading if you don't read the fine print tucked away in Apple's support documents.
I’ve seen dozens of Series 4 and Series 5 models die slow, glitchy deaths because someone thought a hot tub session was totally fine. It wasn't. The seals inside these devices are basically tiny rubber gaskets. They hate heat. They hate soap. And they definitely hate high-velocity water.
The Cold Hard Truth About Water Resistance
First things first: your Apple Watch is not waterproof. No watch is. There is no such thing as a waterproof watch in the electronics world, only varying degrees of water resistance. This resistance isn't permanent. It’s a physical state that degrades over time.
Think of it like the tires on your car. When they're new, they grip the road perfectly. After three years of heat, cold, and friction, that grip fades. The same thing happens to the seals inside your watch. Apple explicitly states that water resistance is not a permanent condition and cannot be rechecked or resealed by Apple Store technicians. Once those seals are compromised, they stay compromised.
If you’re rocking an Apple Watch Ultra or Ultra 2, you’ve got a lot more leeway. Those are rated for 100 meters and are actually EN13319 certified for scuba diving up to 40 meters. But for the rest of the lineup—the Series 9, the SE, or that old Series 6 you’re clinging to—the limit is 50 meters under ISO standard 22810:2010.
That 50-meter rating is deceptive. It doesn't mean you can dive 150 feet deep. It means the watch can withstand the pressure equivalent of being 50 meters deep in still water. If you’re water skiing and you wipe out at 30 mph, the force of that water hitting the watch can far exceed the pressure of a 50-meter dip. That's how screens pop off.
What’s Actually Okay?
Swimming in a pool? Totally fine. Doing laps in the ocean? Generally okay, though you need to rinse it afterward. Showering? This is where it gets tricky.
Technically, the watch can handle the water from a shower. What it can't handle is the Avenue of Doom: shampoos, conditioners, and soaps. These substances are surfactants. They lower the surface tension of water and can bypass the seals much easier than plain tap water. Over months of daily showering, those chemicals eat away at the adhesive. If you want your watch to last four years instead of two, take it off before you lather up.
Understanding the "Water Lock" Myth
I hear this all the time: "I turned on Water Lock so I could go swimming."
Let’s clear this up right now. Water Lock does not seal the watch. It doesn’t flip a tiny mechanical switch that closes the ports. All Water Lock does is two things:

- It locks the screen so the water droplets don't register as "touches" and start texting your ex while you're doing breaststroke.
- It plays a series of low-frequency tones when you turn the Digital Crown to vibrate the speaker diaphragm and eject water.
That's it.
If you forget to turn on Water Lock before you jump in, don't panic. Your watch is just as protected whether the feature is on or off. The protection is physical, provided by gaskets and mesh membranes. The "ejection" sound you hear afterward is helpful for clearing out muffled audio, but it’s not a magical force field.
Salt Water and Chlorine: The Silent Killers
Salt is abrasive. When salt water dries inside the speaker port or around the Digital Crown, it leaves behind tiny crystals. These crystals can act like sandpaper. I’ve felt crowns that became "crunchy" or stuck because the user never rinsed their watch after a beach day.
If you take your Apple Watch into the ocean, you must rinse it under fresh, warm (not hot) tap water immediately afterward. Don't use soap. Just let the water flow over the ports for a good 30 seconds. This is the difference between a watch that works for years and one that fails shortly after your vacation.
When Things Go Wrong: The Warning Signs
How do you know if your watch has been compromised? It usually starts with the battery. If you notice your battery life plummeting from 18 hours to 4 hours overnight, water might be causing a micro-short on the logic board.
Other signs include:

- The screen flickering or showing green lines.
- The Digital Crown becoming unresponsive or "ghosting" (scrolling on its own).
- The "Siri" prompt popping up constantly because the side button is shorting out.
- Muffled audio that doesn't clear up after using the water ejection feature.
If you see these, the damage is likely done. Because Apple doesn't "repair" Apple Watches—they just replace them—liquid damage usually means a full-unit replacement fee unless you have AppleCare+.
The Hot Tub Danger Zone
This is the one that gets people. You’re at a mountain cabin, it’s snowing, and you jump into the hot tub. You think, "Hey, it’s just water."
No. It’s heat.
The Apple Watch is designed to operate in temperatures between 32° and 95° F (0° and 35° C). Most hot tubs are set to 100°–104° F. High temperatures cause the metal and glass to expand at different rates, putting immense stress on the adhesive seals. Furthermore, the steam itself is a problem. Water vapor (gas) can penetrate much smaller openings than liquid water. Keeping your watch on in a sauna or steam room is basically asking for a dead device.
Real-World Advice for Different Models
If you’re wearing an original Apple Watch (Series 0) or a Series 1, keep it away from the pool entirely. Those were only rated as IPX7, meaning they could handle a splash or a rainy run, but weren't meant for submersion.
Series 2 through Series 9 are the "50-meter" crowd. They are the workhorses. You can track your swims with the Workout app, and they’ll handle it beautifully. Just remember that the age of the watch matters. A Series 6 you've worn every day for three years is significantly less water-resistant today than it was the day you unboxed it.
The Apple Watch Ultra changed the game. With its beefed-up seals and depth gauge, it’s a different beast. It’s the only model I’d comfortably take on a jet ski or use for high-speed water sports. Even then, the "no soap" rule still applies.

Leather and Fabric Bands
We haven't talked about the bands yet. If you have a leather Link or a Milanese Loop, don't get them wet. Leather will warp, crack, and eventually smell like a wet dog. Metal links can trap salt and corrode over time. If you’re going in the water, switch to the Ocean Band, the Solo Loop, or the standard Sport Band (fluoroelastomer).
Summary of Actionable Steps
Stop worrying and start being smart about your tech. If you follow these specific habits, you won't be one of those people crying at the Genius Bar.
- Rinse After Every Swim: Whether it’s a pool or the ocean, fresh water is mandatory. Run it under the tap for 30 seconds.
- Skip the Shower: Take the watch off. You aren't closing rings while you're washing your hair anyway. Keeping it away from soap will double the lifespan of its water-resistant seals.
- Avoid High Velocity: No diving off high boards, no water skiing, and no jet skiing unless you have the Ultra model.
- Check Your Gaskets: If your screen is ever repaired by a third party, your water resistance is effectively zero. Most independent shops can't replicate the factory seal.
- Dry It Properly: After a swim, don't just shake it. Use a lint-free, non-abrasive cloth to wipe the casing. Use the Water Lock ejection sound two or three times if the speaker still sounds "muddy."
- Temperature Matters: If the water is uncomfortably hot for you to stay in for an hour, it's too hot for the watch seals. Keep it out of saunas and hot tubs.
The Apple Watch is a marvel of engineering, but it’s still bound by the laws of physics. Water will always try to find a way in. Your job is just to make it as difficult as possible for that to happen. Treat those seals with respect, and your watch will keep ticking—or tapping—long after the warranty expires.
