Apple Watch 11 VS Apple Watch Ultra 3: Comparison

Apple Watch 11 series and the Apple Watch Ultra 3 are the most talked-about models of the new generation of smartwatches in Armenia . At first glance, these two models may seem similar: the same ecosystem, WatchOS 26, similar health monitoring functions. However, in practice, they are very different. In this blog, we present the features of both models, without marketing fluff, making it clear for tech entusiasts whether the premium Ultra 3 model is worth the extra cost.

Design

The Apple Watch 11 has a round, elegant case with a curved display. You can choose between 42 mm and 46 mm sizes. There are aluminum and titanium models. Note that the titanium version of the 11th series is only available as a Cellular model. For the Ultra 3, it comes as the only option with cellular connectivity. The case thickness is 9.7 mm, and the model weighs 29.3–41.7 grams. The standard, durable design includes a single speaker and microphone.

The Ultra 3 is traditionally presented with a relatively larger, corrosion-resistant titanium case with a diagonal of 49 mm. It is protected by the MIL-STD 810H durability standard. The watch is 14.4 mm thick and weighs 61.4 grams. The smartwatch is equipped with two speakers and a triple microphone array with wind protection. There is an Action Button for quick actions.

Performance

Both models are powered by the Apple S10 SIP chip and the same WatchOS 26 operating system, which makes the performance of the two models almost identical. However, in this case, the difference is not in the speed of the core, but in power management and the implementation of individual functions. For example, the battery life of the two models is different. The battery of the 11 series provides about 24 hours of operation, with Low Power Mode up to 38 hours. The battery of the Watch Ultra 3 provides the device with autonomy up to 42 hours, with Low Power Mode up to 72 hours.

Screen

The Watch 11 is equipped with an LTPO3 OLED screen with a brightness of up to 2000 nits. This is sufficient, especially for visibility in sunny conditions. The premium Watch Ultra 3 competes with an LTPO3 OLED screen with a brightness of up to 3000 nits. The relatively larger screen also provides more display space for graphs, maps, or fitness data.

Connectivity

Both models have GPS and 5G connectivity (the 11 series on some models, the Ultra 3 on all models), but the Ultra 3 version has Dual-Frequency GPS, which is more accurate when moving in forests, mountains, or by car. The Ultra 3 also supports the SOS Via Satellite function, which means that you can send distress signals and location messages even in the absence of cellular connectivity. This is especially important for extreme sports enthusiasts who like hiking, mountaineering, etc. From this point of view, the Ultra 3 is perfectly suited as a fitness watch, thanks to the capacious battery, more accurate GPS, and the constant operation of the sensors, and therefore, stable operation even during heavy training. For lovers of an active life, let's delve deeper into this topic:

Health and Fitness

Both models have heart rate, blood oxygen, and sleep tracking features. They are also water resistant, which allows for a more active lifestyle. The Series 11 is water resistant to 50m. This allows you to swim in the pool, be in the rain, or wash your hands without taking off your watch. However, this is not suitable for professional diving: disconnections may occur. The Watch Ultra 3 is a durable watch designed for extreme sports and challenging conditions, offering significant advantages in endurance and navigation. It is also water resistant to 100m and can withstand diving to a depth of 40m (EN13319 certified). This ensures not only swimming, but also hyperactive contact with water.

Accessories

A smartwatch is not only a smart assistant, but also a stylish accessory. Both models have stylish watch bands made of sports, nylon, titanium. For the Watch 11 models, lighter, thinner options are available for comfortable everyday use. For the Ultra 3, the bands are stronger, especially suitable for workouts and water sports.

Conclusion

The Watch 11 is the best choice for those who are looking for an Apple smartwatch with a sleek design, comfortable size and necessary fitness and health functions. The Watch Ultra 3 is the best choice for those who are willing to pay more for durability, longer autonomy, more accurate sensor operation. This is also a conscious choice in terms of safety and security, taking into account the unique connectivity capabilities.
