Huawei Watch D2 users are in for a significant upgrade with the release of firmware version 5.1.0.18(SP2C00M05). This update introduces HarmonyOS 5.1, bringing a fresh new look and enhanced functionalities to your wrist, promising a more engaging and insightful user experience.
A Fresh Perspective: New Layouts and Personalized Watch Faces

One of the most notable visual enhancements in this update is the introduction of a brand-new hex grid layout. This innovative design offers a dynamic way to view your apps. Users can now easily show or hide app names with a simple top-to-bottom swipe, and seamlessly switch between hex grid, traditional grid, and list display layouts, providing greater customization to suit individual preferences.
Expressing your unique style is also made easier with a selection of new pre-installed watch faces. The Tranquil Landscape watch face, with its elegant traditional Chinese design, offers a serene and refreshing aesthetic. For those who prioritize information at a glance, a new watch face with the maximum number of modules allows for extensive customization, packing essential features into even the smallest display areas. Additionally, the color cutout watch face merges fashion and art, providing comprehensive customization options to truly make your device your own. More Calm Scenery styles can be downloaded via the Huawei Health app.
Deeper Insights: Advanced Health Monitoring
Beyond aesthetics, this update significantly enhances the Watch D2’s health tracking capabilities. A key new feature is average sleep HRV (Heart Rate Variability) monitoring. This advanced metric provides valuable insights into your sleep quality and your body’s recovery from fatigue and stress. Complementing this, the feature also continuously monitors your heart rate, respiratory rate, and SpO2 levels during sleep, establishing a physiological baseline and offering timely health alerts to help you maintain optimal well-being.
Streamlined Convenience: Enhanced Features and Rollout Information
The update also includes several practical optimizations designed to make your daily interactions with the Watch D2 even more convenient. The limit for syncing favorite contacts has been expanded to 30, accommodating a wider range of user needs. Furthermore, the alarm creation process has been simplified, now allowing you to edit the alarm name directly while setting it, saving you time and effort.
Please note that this update is being rolled out in phases. While some users have already begun receiving the update, others may need to wait a few more days for it to become available on their devices. Keep an eye out for the notification on your Huawei Watch D2!
