The Apple Watch Series 12 and Apple Watch Ultra 4 bring new health sensors, a new chip, and more detailed recovery insights to Apple's smartwatch lineup, so how do they compare?
Both models feature the S11 chip, 4GB of RAM, 64GB of storage, and the new Health Sensing System, which measures heart rate every five seconds throughout the day. They also share Readiness, Recovery HRV, daytime vitals, improved step tracking, hypertension notifications, sleep apnea notifications, Sleep Score, and more. This means that the Ultra 4's higher price does not buy you more advanced everyday health tracking.
The Apple Watch Series 12 starts at $399, while the Apple Watch Ultra 4 starts at $799. The gap narrows if you want a premium case material, with the titanium Series 12 starting at $699. This year, the Series 12 also gains a ceramic option starting at $899, making it more expensive than the Ultra despite its smaller size and shorter battery life.
The Apple Watch Ultra continues to focus on durability, extended battery life, and additional capabilities for activities like diving and exploration. Our guide helps to answer the question of how to decide which of these two Apple Watches is best for you. The differences between the Apple Watch Series 12 and Apple Watch Ultra 4 are as follows:
For most users, the Apple Watch Series 12 is the better choice. It offers the same performance, health sensors, Readiness insights, and Audio Intelligence features as the Ultra 4 in a thinner, lighter device. The aluminum model delivers these benefits for $400 less, making it the stronger option for everyday use and regular workouts.
The Ultra 4's most broadly useful advantage is battery life. Its longer endurance makes overnight wear and extended workouts easier to fit around charging. You do not need to be an endurance athlete to appreciate less frequent charging, but the premium is easier to justify if the Series 12 cannot comfortably cover your usual activities and charging habits.
For hiking away from cellular coverage, recreational scuba diving, or very long events, the Ultra has a clearer purpose. Satellite communications, dual-frequency GPS, greater water resistance, and extended workout modes address needs that the Series 12 cannot fully meet. The Action button and brighter display may also appeal to enthusiasts who simply want more capable hardware.
Size and appearance remain substantial trade-offs. The Ultra is considerably bulkier and heavier despite offering a display only slightly larger than the 46mm Series 12's. The Series 12 is more discreet and offers polished titanium and ceramic finishes, making it better suited to buyers who prioritize comfort or appearance. Try on the Ultra before buying if you are unsure about its size.
The decision becomes closer if you already want the titanium Series 12, since its starting price is just $100 below the Ultra's. At that point, paying more for longer battery life and additional hardware is reasonable if you are comfortable with the larger case. The $899 ceramic Series 12 is primarily a choice of material and finish; choose it because you prefer its appearance, rather than expecting more capabilities than the $799 Ultra.
