The Apple Watch Ultra and Apple Watch Ultra 2 feature a dedicated “Night Mode” specifically designed for outdoor athletes, divers, hikers, and stargazers. When activated, Night Mode shifts the entire watch face into an intense, high-contrast monochrome red filter while blacking out all background pixels.
Red light wavelengths have the least impact on the human eye’s rhodopsin pigment, preserving your natural scotopic (night-adapted) vision in pitch darkness while eliminating glare that could disturb others during nocturnal activities. Here is how to enable Night Mode, configure automatic activation, and customise supported watch faces.
Supported Watch Faces for Night Mode
Night Mode is an exclusive feature engineered for the Apple Watch Ultra display hardware and is supported natively on two primary watch faces:
- Modular Ultra: The data-dense digital watch face designed for endurance athletes and navigation.
- Wayfinder: The technical analogue/digital compass watch face built for exploration and hiking.
Standard watch faces (such as Infograph or Activity Digital) do not support the dedicated red Night Mode filter, though they can be customised with red colour schemes in the Watch app.
Method 1: Turn On Night Mode via Face Customisation
Starting in watchOS 10 and continuing through watchOS 11, Apple streamlined Night Mode controls into the watch face customisation screen:
- Wake your Apple Watch Ultra display and navigate to the Wayfinder or Modular Ultra watch face.
- Press and firmly hold the centre of the screen until the watch face selector interface appears.
- Tap the Edit button at the bottom of the screen.
- Swipe left through the customisation screens until you reach the Night Mode panel (located past “Dial”, “Bezel”, and “Colour”).
- Turn the Digital Crown to choose your preferred setting:
- Auto: The ambient light sensor continuously monitors lighting levels. When your environment drops below a specific lux threshold, the watch automatically shifts into red Night Mode. When ambient light increases, it reverts to standard colour.
- On: Permanently locks the watch face into red Night Mode, regardless of daylight or room illumination.
- Off: Disables Night Mode entirely, keeping standard colours active even in pitch darkness.
- Press the Digital Crown twice to save your selection and return to the active watch face.
Method 2: Configure Night Mode from Your iPhone
If you prefer adjusting settings on a larger screen, you can configure your Ultra watch faces using the Apple Watch companion app on your iPhone:
- Open the Watch app on your paired iPhone.
- Under the My Faces carousel at the top of the “My Watch” tab, tap your active Wayfinder or Modular Ultra face.
- Scroll down to the Night Mode section.
- Select Auto, On, or Off.
- The change syncs instantly to your Apple Watch Ultra over Bluetooth or Wi-Fi.
Why the Auto Setting Is Recommended for Outdoor Enthusiasts
For most users, selecting Auto provides the best hands-free experience. When stepping into a dark tent, navigating nighttime trail runs, or checking navigational coordinates under a starlit sky, the ambient light sensor triggers red illumination without requiring manual interaction. As soon as you switch on a headlamp or step indoors, the screen seamlessly shifts back to crisp multicolour readouts.
Utilising Night Mode protects your dark adaptation, maximises readability during extreme nighttime conditions, and leverages the full capabilities of your Apple Watch Ultra display.
