Apple continues to dominate the smartwatch market with its innovative Apple Watch lineup. For those looking to upgrade or enter the Apple Watch ecosystem, deciding between the robust Apple Watch Ultra 2 and the refined Apple Watch Series 10 can be challenging. This comprehensive guide aims to Compare Apple Watch Ultra 2 and Series 10 across every significant feature, helping you determine which smartwatch best suits your needs and lifestyle.
Before diving into the specifics, let’s quickly review the pricing structure for both models:
Apple Watch Pricing: Series 10 vs. Ultra 2
| Model | Price (USD) | Cellular Option |
|---|---|---|
| Apple Watch Series 10 Aluminum (42mm) | $399 | +$100 |
| Apple Watch Series 10 Aluminum (46mm) | $429 | +$100 |
| Apple Watch Series 10 Titanium (42mm) | $699 | +$50 (Estimate) |
| Apple Watch Series 10 Titanium (46mm) | $749 | +$50 (Estimate) |
| Apple Watch Ultra 2 (Titanium, Cellular) | $799 | Included |
It’s important to note that the Apple Watch Ultra 2 comes standard with cellular connectivity, while it’s an optional upgrade for the Series 10, except for the titanium models where cellular inclusion might adjust the price slightly. The base price of the Series 10 starts significantly lower, but the Ultra 2 packs in premium features that justify its higher price tag for specific users.
Now, let’s delve into the core differences by examining the hardware.
Hardware Face-Off: Apple Watch Ultra 2 vs. Series 10
The physical attributes of the Apple Watch Ultra 2 and Series 10 immediately highlight their distinct target audiences. The Ultra 2 is built for extreme conditions and outdoor enthusiasts, while the Series 10 prioritizes everyday wearability and sleek design.
Here’s a detailed breakdown of the hardware differences:
-
Case Size: Apple Watch Ultra 2 boasts a larger 49mm case, designed for maximum visibility and impact resistance. The Series 10 offers more traditional sizes with 42mm and 46mm options, catering to a wider range of wrist sizes and preferences.
-
Case Material: The Ultra 2 uses a robust titanium case as standard, providing exceptional durability and a premium feel. The base Series 10 models come with aluminum cases, making them lighter and more affordable. However, a titanium version of the Series 10 is also available at a higher price point, bridging the material gap but not the overall ruggedness.
-
Action Button: A key differentiator is the dedicated ‘Action’ button on the Apple Watch Ultra 2. This customizable button allows for quick access to workout modes, compass waypoints, or other frequently used functions, essential for athletes and adventurers. The Series 10 lacks this physical shortcut.
-
Precision Start: For workout enthusiasts, the Ultra 2 offers ‘Precision Start’ for immediate workout initiation via the Action button, contrasting with the 3-second countdown on the Series 10. While seemingly minor, this can be crucial for activities where every second counts.
-
Cellular Connectivity: As mentioned, cellular is standard across all Apple Watch Ultra 2 models. For the Series 10, cellular is optional for aluminum models and potentially included or priced differently for titanium versions. This makes the Ultra 2 inherently more independent from your iPhone for calls, messages, and data.
-
Battery Life: Battery performance is a significant advantage for the Ultra 2. It delivers approximately 2 days of battery life in normal use, compared to about 1 day for the Series 10. In low power mode, the Ultra 2 extends to around 72 hours, while the Series 10 reaches about 36 hours. This extended battery life is a major draw for multi-day expeditions or users who dislike frequent charging.
-
GPS Battery Life: For GPS-intensive activities, the Ultra 2 excels with 12+ hours of GPS battery life, compared to the Series 10’s 7 hours. The Ultra 2 also offers extended GPS modes for even longer tracking, further solidifying its outdoor and endurance focus.
-
Depth Gauge and Water Resistance: The Apple Watch Ultra 2 is engineered for serious water activities, featuring a depth gauge functional to 40m/131ft and certified for scuba diving (EN13319 standard compliance). The Series 10, with a depth gauge to only 6m/20ft and 50m water resistance, is suitable for swimming and shallow water activities but not for diving. The Ultra 2 boasts 100m water resistance, double that of the Series 10.
-
Emergency Siren: In emergency situations, the Ultra 2 includes an 86dB emergency siren, a feature absent in the Series 10, adding a layer of safety for remote adventures.
-
GPS Technology: The Ultra 2 incorporates multiband/dual-frequency GPS/GNSS for enhanced location accuracy, particularly in challenging environments like urban canyons or dense forests. The Series 10 uses standard GPS/GNSS. While real-world accuracy differences may be subtle in many situations, the multiband GPS in the Ultra 2 offers superior performance in demanding conditions.
-
Chipset: The Apple Watch Ultra 2 is powered by the S9 SiP (System in Package), while the Series 10 features the newer S10 SiP. Currently, performance differences are negligible for most daily tasks. However, the S10 SiP in the Series 10 may unlock future software features, particularly in AI and processing, although this is speculative and not a current advantage.
-
Microphones and Speakers: The Ultra 2 has a three-microphone array for improved call clarity, especially in noisy environments, while the Series 10 has a single microphone. Despite this, the Series 10 leverages the S10 SiP for voice isolation, aiming for similar call quality with fewer mics. Interestingly, while the Ultra 2 has dual speakers and the Series 10 has a single, audio loudness tests show comparable output, suggesting effective speaker design in the Series 10.
-
Display Protection and Brightness: The Ultra 2 uses a sapphire crystal display, known for its scratch resistance, while the base Series 10 uses Ion-X glass (the titanium Series 10 upgrades to sapphire crystal). The Ultra 2 also boasts a significantly brighter display with a peak brightness of 3,000 nits, compared to the Series 10’s 2,000 nits. Both use LTPO OLED displays, but the Ultra 2 utilizes LTPO2 OLED, and the Series 10 uses LTPO3 OLED. While LTPO3 in Series 10 offers slightly improved off-angle viewing, in practice, the difference is minimal compared to the Ultra 2. Both are exceptionally bright and readable even in direct sunlight.
-
Display Design: The Ultra 2 features a completely flat screen, while the Series 10 has curved edges on the display glass, a subtle aesthetic difference.
-
Weight and Thickness: The robust build of the Ultra 2 results in a heavier and thicker case. The Ultra 2 case weighs 61.4g-61.8g, with a 14.4mm thickness. The Series 10 is significantly lighter and thinner, ranging from 29.3g-41g and 9.7mm thickness, enhancing comfort for everyday wear, especially for sleep tracking.
-
Button Guard and Ruggedness Certifications: The Ultra 2 has a button guard around the Digital Crown and side button for added protection. It’s also validated to MIL-STD 810H standards, signifying military-grade durability, a certification the Series 10 lacks.
-
Back Case Material: The Ultra 2 uses a ceramic and sapphire crystal back case, while the Series 10 uses a metal and sapphire crystal back case. This difference in materials contributes to the Ultra 2’s enhanced durability.
-
DLC Coating: The Apple Watch Ultra 2 Black features a protective DLC (Diamond-Like Carbon) coating on the titanium, further enhancing scratch resistance. Neither the standard Ultra 2 nor the Series 10 has this coating.
-
Charging Speed: Interestingly, despite its larger battery, the Apple Watch Ultra 2 fast charges to 80% in 1 hour, whereas the Series 10 reaches 80% in a quicker 30 minutes.
Software Similarities and Minor Differences
When it comes to software, the gap between the Apple Watch Ultra 2 and Series 10 narrows significantly. Both run WatchOS 11 and share the vast majority of features.
Here are the minor software discrepancies:
-
Exclusive Watch Faces: The Ultra 2 has the exclusive ‘Modular’ watch face, optimized for displaying a wealth of information. It also features a ‘Night Mode’ watch face that turns the display red for better visibility in low-light conditions, preserving night vision. These specialized watch faces are not available on the Series 10.
-
Data Fields in Sport Modes: The Ultra 2 allows customization of up to 7 data fields per sport mode setting, offering more in-depth real-time metrics for athletes. The Series 10 is limited to 6 data fields (including the time).
-
Precision Start (Software Integration): While ‘Precision Start’ is initiated by the Ultra 2’s Action button (hardware), the instant workout start functionality is also a software feature unique to the Ultra 2.
