💧 Water Lock — Always Enable

The most important swim feature: Before getting in the water, swipe down on the watch and tap the water drop icon (Water Lock). Locks the screen to prevent water tapping. After swimming, rotate the Digital Crown to expel water from the speaker. Apple's swim experience only works if you remember to enable Water Lock.

You can also set Water Lock to auto-enable when you start a Swimming Workout: Settings → Workout → Swimming Workouts → Auto Water Lock.

⌚ Bands for Swimming

Apple Sport Band — only silicone option

$49

Silicone. Doesn't soak water like fabric bands. Salt-water resistant. Easy to rinse. The default swimmer band.

Apple Ocean Band (Ultra-only)

$99

For Apple Watch Ultra, the Ocean Band is purpose-built for water sports. Flexible silicone. Tubular design for water flow. Secure clasp.

What NOT to wear swimming: Nylon Sport Loop — soaks water, smells. Leather bands — destroyed by chlorine and salt water. Milanese Loop or Link Bracelet — fine briefly but salt water corrodes the steel over time. Stick with silicone for any regular swimmer.

🎧 Underwater Headphones

H2O Audio Stream 3 — bone conduction swim headphones

~$170

The best swim headphones that pair with Apple Watch. Bone conduction = audio works underwater (regular Bluetooth doesn't). Stream music directly from Apple Watch via Bluetooth while doing laps. Game-changer for pool training.

Note: AirPods are not designed for swimming. Don't try.

🧪 Salt Water Care

If swimming in ocean, lake, or pool with chlorine:

Rinse Apple Watch in fresh water within 30 minutes of swimming
Pat dry with a microfiber cloth
Remove the band weekly and clean it separately
Don't use soap (can affect water-resistance seals over time)

Salt water corrosion is gradual — watches that aren't rinsed develop case ring damage over months/years.

📱 Apps for Swimmers

Apple Workouts (built-in) — Pool Swim + Open Water Swim track stroke type, laps, distance, heart rate, calories
Oceanic+ — for Ultra 2, transforms into recreational dive computer ($10/mo or one-time)
MySwimPro — guided pool workouts, technique drills, Apple Watch integration
Garmin Connect — works with Garmin Swim 2 (alternative to Apple Watch for serious swimmers)

🛡️ AppleCare+ for Swimmers

Water-resistant ≠ water-proof forever. Apple Watch's water resistance degrades over years of swim use. AppleCare+ covers water damage incidents. Strongly recommended for regular swimmers.
