COLMI L28 Smart Watch

The COLMI L28 smartwatch combines a refined finish and compact design with a slim 7.9 mm profile. Its 48 × 41.5 mm case is designed to sit comfortably on the wrist.

AMOLED display and watch faces

The 1.32-inch AMOLED touchscreen has a resolution of 466 × 466 pixels for clear detail and vivid color. Its curved, frameless design complements the case, while the Always-on Display lets you check the time without waking the screen. Choose from more than 100 watch-face styles and customize the interface to suit your preferences.

Health and wellness monitoring

The VC30F optical heart-rate sensor supports continuous pulse monitoring and vibration alerts when irregularities are detected. Blood oxygen (SpO₂) measurement helps you monitor oxygen levels, including during sleep. Sleep analysis separates sleep into REM, light and deep phases to help you review sleep quality. Women's health features track the menstrual cycle, ovulation and fertile days.

AI features

The built-in GPT function can answer questions and assist with everyday tasks. AI Watchface lets you create personalized watch faces based on your preferences and style.

Activity tracking

With more than 100 sports modes—including running, cycling, jump rope, yoga and golf—the L28 tracks workout duration, heart rate and calories burned. Activity data can help you review training and work toward your goals.

Calls and smart functions

Bluetooth 5.2 connectivity, a built-in microphone and speaker with HD Voice support calls from the watch. You can answer or reject calls, browse contacts and view call history. The watch also displays notifications from apps such as WhatsApp, SMS and Facebook. A smart voice assistant provides hands-free access to functions and information.
