The Apple Watch Series 4 is water resistant up to 50 meters, making it suitable for swimming but not for deep diving or high-velocity water activities.
Understanding Water Resistance in the Apple Watch Series 4
Apple Watch Series 4 carries an official water resistance rating of 50 meters under ISO standard 22810:2010. This means it can handle shallow-water activities like swimming in a pool or ocean. However, it’s essential to note that “water resistant” is not the same as “waterproof.” The Series 4 is designed to withstand splashes, rain, and brief submersion but isn’t built for scuba diving, waterskiing, or other activities involving high-velocity water or deep submersion.
Water resistance ratings are often misunderstood by consumers. The “50 meters” rating does not mean the watch can be taken to a depth of 50 meters underwater safely. Instead, it’s a laboratory test simulating static pressure equivalent to that depth. Real-world conditions like movement and temperature changes can affect the watch’s performance against water.
What Activities Are Safe with the Apple Watch Series 4?
The Apple Watch Series 4 thrives in everyday scenarios involving water exposure:
- Swimming: You can wear it while swimming laps in a pool or open water.
- Showering: It tolerates showers without issue, though soap and shampoos might degrade seals over time.
- Rain and sweat: The watch handles rain and sweat without any problems.
However, Apple explicitly advises against using the watch for:
- Diving: Scuba diving or deep-water diving can expose the device to pressures beyond its design.
- High-speed water sports: Activities like waterskiing or jet skiing involve intense water impact that might damage internal seals.
- Hot tubs and saunas: High temperatures combined with steam can degrade waterproof seals and compromise performance.
The Technology Behind Water Resistance
Apple achieves water resistance through multiple design features:
- Tightly sealed case: The casing uses gaskets and adhesives to prevent water ingress.
- Sapphire crystal glass: The display glass is tough and less prone to cracking under pressure.
- Sensors designed for wet conditions: Optical heart rate sensors adapt to wet skin to maintain accuracy.
Moreover, Apple includes a unique feature called the Water Lock. When activated before entering water-based activities, this locks the screen to prevent accidental taps from splashes. After exiting water, turning the Digital Crown ejects any trapped moisture from the speaker using sound vibrations.
The Role of Water Lock Mode
Water Lock is crucial for protecting functionality during swimming or showering sessions. Without this mode enabled, accidental screen touches caused by wet fingers could disrupt workouts or apps. Activating it also helps preserve speaker health by forcing out residual water from its tiny openings.
Limitations of Water Resistance in Apple Watch Series 4
Despite its impressive resistance rating, there are clear limitations users must understand:
The watch’s seals degrade naturally over time due to wear and tear. Frequent exposure to soaps, lotions, perfumes, chlorinated pools, saltwater, and extreme temperatures accelerates this degradation. This means a brand-new watch will handle water better than one that’s been used heavily for years.
If you notice fogging inside the display or irregular sensor behavior after exposure to moisture, it might indicate compromised waterproofing. In such cases, immediate professional assessment is recommended.
The warranty also does not cover liquid damage caused by misuse or exceeding recommended guidelines. So pushing your luck with deep dives or hot tubs risks voiding your coverage.
Avoiding Common Mistakes That Damage Water Resistance
- Avoid pressing buttons underwater unless necessary; this can break seals if done improperly.
- Dried salt or chlorine residue on the watch after swimming can corrode seals—always rinse with fresh water afterward.
- Avoid exposing your watch to sudden temperature changes (e.g., jumping into cold water after being in hot sun), which may cause condensation inside.
Comparing Apple Watch Series 4 With Other Models
Apple has steadily improved its watches’ waterproof capabilities over generations. Here’s how Series 4 stacks up against others:
| Model | Water Resistance Rating | Main Use Case |
|---|---|---|
| Apple Watch Series 3 | 50 meters (ISO 22810:2010) | Swimming & casual water exposure |
| Apple Watch Series 4 | 50 meters (ISO 22810:2010) | Swimming & casual water exposure with improved sensors & durability |
| Apple Watch Series 5 & later (non-ULTRA) | 50 meters (ISO 22810:2010) | Diving not recommended; similar use cases as Series 4 but with enhanced features like ECG & always-on display |
| Apple Watch Ultra (2022+) | 100 meters (EN13319 certified) | Diving & extreme sports; suitable for recreational scuba diving up to 40 meters depth |
While the Series 4 shares the same official rating as Series 3 and later standard models, improvements in materials and software make it more reliable during prolonged swim sessions.
Caring for Your Apple Watch After Water Exposure
Proper maintenance extends your watch’s lifespan significantly:
If you’ve been swimming in saltwater or chlorinated pools:
- Rinse thoroughly with fresh water immediately afterward.
- Dab dry gently using a soft cloth—avoid harsh rubbing which might damage coatings.
If you wore your watch during heavy sweating workouts or rainy days:
- wipe clean regularly to prevent buildup of grime that could compromise seals over time.
Avoid charging your Apple Watch when it’s wet; moisture near charging ports may cause corrosion or short circuits. Wait until completely dry before plugging it in again.
Troubleshooting Water-Related Issues on Your Apple Watch Series 4
Sometimes moisture finds its way inside despite precautions:
- If you notice screen fogging under glass—place your watch in a dry environment with moderate airflow (avoid direct heat) to allow evaporation naturally over several hours.
- If sensors behave erratically after exposure—perform a soft reset by holding down both side buttons until you see the Apple logo again; this often recalibrates sensor functions affected by moisture presence temporarily.
If problems persist beyond these steps, consult an authorized service provider promptly.
The Verdict – Is Apple Watch Series 4 Waterproof?
The straightforward answer is no—the Apple Watch Series 4 isn’t waterproof but rather water resistant up to a depth of 50 meters under controlled conditions. It excels at handling everyday wet scenarios including swimming laps or getting caught in rainstorms without skipping a beat.
However, pushing it beyond these limits risks permanent damage due to pressure extremes or chemical exposure from soaps and hot tubs. Following best practices like using Water Lock mode during aquatic activities and rinsing off afterward will keep your device running smoothly.
