Apple and Samsung released their latest premium smartwatches this summer: the Apple Watch Ultra 4 and Galaxy Watch Ultra 2. Both feature titanium bodies, 100-meter water resistance, and EN13319 depth gauge ratings for diving. Samsung adds IP69K dust and water resistance, while Apple offers IP6X dust protection. Both include 64GB storage.

Internals differ significantly. Samsung uses a Snapdragon Wear Elite chip with Google Gemini AI and 2GB RAM. Apple deploys its S11 chip with enhanced Siri and Audio Intelligence features. Display tech varies: Samsung's circular Super AMOLED measures 1.52 inches with 5,000 nits peak brightness; Apple's rectangular Retina LTPO3 OLED spans 49mm x 44mm (~1.9 inches) at 3,000 nits. Samsung is thinner at 10.7mm vs Apple's 12mm.

Battery claims show Samsung at 60 hours standard use with 800mAh capacity and 40% charge in 30 minutes. Apple promises 50 hours (84 in Low Power Mode) and 18 hours extra from 15-minute fast charging. Apple's Extended Workout Mode delivers 25 hours with continuous GPS and heart rate monitoring. Both target serious athletes with advanced health and safety features.
