# Apple Watch Ultra 3 and Series 11: Innovations in Display Technology with watchOS 26
Apple persists in advancing the smartwatch arena with the launch of the Apple Watch Ultra 3 and Series 11, both featuring cutting-edge LTPO3 display technology. This advancement not only elevates the visual quality but also boosts energy efficiency, marking a notable enhancement for users.
## LTPO3 Display Technology
The LTPO3 (Low-Temperature Polycrystalline Oxide) displays incorporated in the Apple Watch Ultra 3 and Series 11 facilitate an impressive 1Hz refresh rate. This signifies that the display can refresh every second, as opposed to every minute, in Always-On mode. This aspect is especially advantageous for users who wish to keep a continuously visible seconds hand or digital seconds display, even when their wrist is stationary.
## watchOS 26 Enhancements
With the rollout of watchOS 26, Apple has improved 26 watch faces to fully utilize the 1Hz refresh rate. This upgrade allows for a more lively and interactive interface, as users can experience a ticking seconds hand or a digital seconds display at all times.
### Supported Watch Faces
The following watch faces and applications have been fine-tuned to support the 1Hz refresh rate:
– Activity Analog

Alongside the watch faces, both the Stopwatch and Timer applications can showcase real-time advancements in Always-On mode, enhancing usability for those who depend on these tools.
## Exclusive Features and Compatibility
It is critical to recognize that certain watch faces are reserved for Hermès or Ultra models. Additionally, the Apple Watch Series 10 also accommodates the 1Hz refresh rate for faces and applications. At the time of the Series 10’s introduction, merely three watch faces were capable of utilizing this feature: Flux, Reflections, and Activity Digital.
## Conclusion
The Apple Watch Ultra 3 and Series 11, integrated with watchOS 26, signify a remarkable progression in smartwatch technology. The sophisticated LTPO3 displays and the revamped watch faces offer users a more captivating and effective experience. As Apple continues to enhance its offerings, these advancements establish a new benchmark for user expectations from their wearable tech.
