Apple Watch Ultra 2 & Apple Watch Series 10 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Apple Watch Ultra 2 rather than the Apple Watch Series 10.
Why Do I Recommend The Apple Watch Ultra 2?
- The Apple Watch Ultra 2 has a 3,000-nit Retina LTPO OLED display for improved visibility in direct sunlight and better readability during outdoor activities, whereas the Apple Watch Series 10 has a 2,000-nit Retina LTPO OLED display.
- Apple Watch Ultra 2 comes with dual-frequency (L1 + L5) GPS for more precise location tracking in dense urban areas and remote terrains, while the Apple Watch Series 10 uses standard single-frequency GPS.
- It features MIL-STD 810H durability with a 100-meter water resistance rating and EN13319 dive certification for reliable performance in extreme environments, whereas the Apple Watch Series 10 has a 50-meter water resistance rating without military or dive certification.
- The Apple Watch Ultra 2 includes a depth gauge rated up to 40 meters for accurate underwater pressure readings during scuba diving, while the Apple Watch Series 10 has a depth sensor limited to approximately 6 meters.
- Apple Watch Ultra 2 has dual speakers and three microphones for louder sound output and clearer voice capture in noisy conditions, whereas the Apple Watch Series 10 has a single speaker and one microphone.
- It provides up to 36 hours of typical battery life and up to 72 hours in low-power mode for extended use on long trips, compared to the Apple Watch Series 10’s 18 hours of typical use and up to 36 hours in low-power mode.
- The Apple Watch Ultra 2 uses a rugged 49-mm titanium case with a button guard for enhanced impact resistance during intense activities, whereas the Apple Watch Series 10 uses a slimmer 42-mm or 46-mm case without a button guard.
- Apple Watch Ultra 2 comes with sapphire crystal front glass and a ceramic + sapphire back for increased scratch resistance and long-term durability, while the Apple Watch Series 10 uses Ion-X glass.
Maybe the Apple Watch Series 10 price can make you comfortable because it’s a little bit cheaper than the Apple Watch Ultra 2. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
