Apple Watch Ultra 3: the top new products of 2025

Two years after the previous model, Apple is preparing to release the Apple Watch Ultra 3. The smart watch is expected to retain its recognizable design, but will get a number of technological improvements, from health monitoring to support for satellite communications. Here’s what we know about the new product and how it will change the user experience.

Hypertension Monitoring

One of the key new features will be hypertension detection, as reported by insider Mark Gurman. Unlike traditional tonometers, the Apple Watch Ultra 3 won’t display accurate systolic and diastolic blood pressure readings. Instead, the watch will track the trend of rising readings and alert the user to the risks. When notified, a doctor can be contacted for an in-depth diagnosis.

Systolic blood pressure 

This feature is especially important because hypertension is often asymptomatic, leading to heart attacks and strokes. Already, the Apple Watch can detect arrhythmias and take ECGs, but patent disputes have temporarily blocked the measurement of blood oxygen levels in the U.S.

Brighter and more responsive: next-generation display

The Apple Watch Ultra 3 is expected to switch to the LTPO3 OLED panel that the Series 10 previously received. Compared to the current LTPO2, the new technology will increase the refresh rate in Always-On mode, which will allow for the addition of “live” second hands on the watch faces. It will also improve brightness when viewed at an angle, up to 40 percent over previous models.

S11 chip: more power or compactness?

In two years without an update, Apple may introduce a new processor – probably the S11. The S10 chip debuted in the Series 10, which didn’t get more powerful than the S9, but it did shrink in size. If the S11 stays on trend, it would make room inside the Ultra 3 for a larger battery or other components.

The S11 could be the next big thing.

Satellite communications: safety out of range

According to leaks, the Apple Watch Ultra 3 will get satellite communication support, a feature previously only available for the iPhone. This will allow you to send text messages even without Wi-Fi and cellular networks. Initially, the option will work for emergency calls, but it could expand to regular messages in the future, as with iOS 18.

According to the leaks, Apple Watch Ultra 3 will have support for satellite communications, a feature previously only available on the iPhone.

For travelers, divers, and extreme sports enthusiasts, this will be an extra layer of security. The competition will be Garmin devices with similar capabilities. For now, Apple doesn’t plan to charge for the satellite connection, offering two years of free use.

5G RedCap: the evolution of mobile networks

Apple is replacing Qualcomm modems with MediaTek chips to support 5G RedCap, a standard optimized for low-power gadgets. The current Apple Watch uses 4G LTE, though iPhones moved to 5G back in 2020. RedCap will provide stable connectivity without wasting battery life.

Metal back panel and fast charging

In a design inspired by the Series 10, Apple will redesign the Ultra 3’s back cover. Instead of ceramic and sapphire glass, there will be a metal panel with a built-in antenna and larger charging coil. This will improve connectivity and shorten charging time: up to 80 percent in 30 minutes versus 60 minutes for the Ultra 2.

The Apple Watch Ultra 3 will thus emphasize safety and autonomy, which is critical for its target audience of athletes and travelers. Hardware and software updates will strengthen Apple’s position in the premium gadget segment, offering not just a watch, but a feature-rich companion for health and adventure. An official announcement is expected in September 2025.
