Cost and Value Proposition

Starting with pricing, the Apple Watch SE 3 is the most accessible at $249, making it an excellent choice for newcomers or those upgrading without a hefty investment. However, this affordability comes with compromises, such as the absence of advanced health sensors like ECG and blood oxygen measurement.

The Apple Watch Series 11 begins at $399 for the aluminum GPS-only model, with the titanium GPS + Cellular variant priced at $699, offering a blend of premium materials and enhanced connectivity.

At the premium end, the Apple Watch Ultra 3 commands $799, reflecting its rugged titanium build, satellite communication capabilities, superior water resistance, and extended battery life.

In summary, the SE 3 suits budget-conscious buyers, the Series 11 balances features and cost effectively, and the Ultra 3 caters to users demanding durability and cutting-edge functionality.

Design and Dimensions

Apple Watch Series 11 vs SE 3 vs Ultra 3 Design Comparison

The SE 3 is the most compact, available in 40mm and 44mm aluminum cases, making it lightweight and comfortable, especially for smaller wrists. Its design is contemporary, though the bezels are slightly more prominent compared to the other models.

The Series 11 offers larger 42mm and 46mm options, crafted from aluminum or titanium. The titanium variant combines elegance with durability while remaining lightweight. Its narrower bezels maximize screen space, enhancing readability and app navigation-ideal for users who prioritize style and functionality.

The Ultra 3 stands out with a bold 49mm titanium case, designed for high visibility and rugged use. It features oversized buttons, a prominent Digital Crown, and a raised bezel to shield the display. While its size may not suit everyone, it appeals to those seeking a tough, sport-focused smartwatch.

Display Quality

The SE 3 introduces an always-on display to the SE series, utilizing an LTPO OLED panel with up to 1,000 nits brightness. While adequate indoors, it can appear dim under direct sunlight, and its thicker bezels reduce usable screen area. Nonetheless, the always-on feature is a valuable upgrade for entry-level users.

The Series 11 enhances the visual experience with an LTPO3 OLED screen reaching 2,000 nits brightness. Its larger sizes provide more display area-989mm² for 42mm and 1,220mm² for 46mm-making it easier to view notifications, maps, and messages even in bright conditions.

The Ultra 3 boasts Apple’s brightest and largest display at 1,245mm² and up to 3,000 nits brightness, ensuring exceptional clarity in harsh environments like underwater or desert settings. Its wide-angle LTPO3 OLED panel maintains sharp visuals from various wrist angles.

Processing Power and User Experience

All three watches are powered by Apple’s S10 chip, delivering smooth performance, quick app launches, and fluid animations across the board.

However, the Series 11 and Ultra 3 leverage the S10 chip alongside the LTPO3 display technology to optimize power consumption, extending battery life. They also support on-device Siri that accesses health data locally, enhancing privacy and responsiveness.

The SE 3, while equipped with the same chip, lacks support for some advanced health sensors, limiting its feature set. It remains a capable device but doesn’t unlock the full potential of the S10 chip like its higher-tier counterparts.

Connectivity Features

The SE 3 offers GPS and optional GPS + Cellular models with 5G support, covering essential functions such as calls, messaging, streaming, and navigation, but it does not include satellite emergency services.

The Series 11 matches these connectivity options and adds Precision Finding for locating your iPhone in crowded or unfamiliar places, enhancing convenience when separated from your phone.

The Ultra 3 advances connectivity with dual-frequency precision GPS and combined cellular plus satellite communication, enabling navigation in remote areas and emergency SOS via satellite when traditional networks are unavailable-ideal for explorers and outdoor enthusiasts.

Health and Fitness Tracking Capabilities

Apple’s health monitoring features distinguish these models significantly.

The SE 3 covers fundamental metrics such as heart rate, irregular rhythm alerts, sleep tracking, temperature sensing, sleep apnea notifications, and cycle tracking-sufficient for general wellness monitoring but lacking advanced diagnostics.

The Series 11 expands on this with ECG functionality, blood oxygen measurement, and hypertension alerts, providing a more comprehensive health overview. When paired with Apple Fitness+, it becomes a powerful tool for fitness and health management.

The Ultra 3 further enhances these features, adding specialized sensors for extreme sports, a depth gauge up to 40 meters, water temperature monitoring, and an integrated siren for emergencies, making it a safety companion for athletes and adventurers.

Build Quality and Durability

The SE 3 is water-resistant up to 50 meters, suitable for swimming and daily wear, but its Ion-X glass is more vulnerable to scratches compared to higher-end models.

The Series 11 offers 50-meter water resistance with aluminum or titanium cases, the latter featuring sapphire crystal glass for superior scratch protection. It supports snorkeling and includes a depth gauge for dives up to 6 meters, enhancing its versatility in aquatic activities.

The Ultra 3 is engineered for the toughest conditions, boasting 100-meter water resistance, titanium construction, and depth support up to 40 meters. It withstands high-speed water sports, climbing, and rugged outdoor use with ease.

The raised bezel on the Ultra 3 offers additional protection against impacts.

Battery Performance

The SE 3 delivers up to 18 hours of typical use and extends to 32 hours in Low Power Mode. Charging from zero to 80% takes about 45 minutes, necessitating nightly charging for most users.

The Series 11 improves endurance with 24 hours of regular use and 38 hours in Low Power Mode. Its faster charging (0-80% in roughly 30 minutes) allows quick top-ups during short breaks.

The Ultra 3 excels with 42 hours of standard use and up to 72 hours in Low Power Mode, ideal for extended trips or intense activities. Although its charging speed matches the SE 3’s 45-minute 0-80% charge, its longer battery life reduces charging frequency.

Summary and Recommendations

  • The Apple Watch Series 11 strikes the best balance, combining advanced health features, a superior display, and longer battery life at a moderate price.
  • The Apple Watch SE 3 is tailored for newcomers and budget-minded users who need essential smartwatch functions.
