Features and Construction

The UM90 combines communication capabilities with extensive tracking in a compact, wearable format. Its construction focuses on delivering a clear user interface and reliable connectivity for everyday and athletic use.
Material and Build
The watch face is protected by a glass screen material, providing a durable surface for the 1.28-inch display. The wristband is made from leather, offering a traditional watch aesthetic and an adjustable fit. The case itself measures 46.2mm in width, 46.2mm in length, and 11.7mm in thickness, contributing to an overall light weight of just 26.1 grams. This combination of materials results in a device that is designed to be worn comfortably throughout the day and during various activities.
Size and Practical Fit
With a case dimension of 46.2mm by 46.2mm, the UM90 presents a noticeable presence on the wrist without being overly bulky. The supplied leather strap is adjustable and is confirmed to fit wrist circumferences ranging from 140mm to 210mm, accommodating a wide variety of users. The 11.7mm profile and 26.1-gram weight are engineered to balance screen size with wearability, ensuring the device remains practical for continuous wear during both sedentary periods and physical exercise.
Uses and Placement

This smartwatch serves dual purposes: as a convenient communication hub and a detailed fitness companion. Its functionality is split between managing daily digital life and supporting targeted physical training.
Event or Professional Use
For athletic or training scenarios, the UM90's 24 sports modes allow for precise activity tracking. Modes include cricket, baseball, spinning, rugby, outdoor running, rowing, and swimming, among others, enabling users to record data specific to their workout. The IP67 waterproof rating ensures the watch can withstand immersion, making it suitable for swimming and use in rainy conditions. Features like distance measurement, calorie counting, and exercise tracking provide athletes with tangible metrics to review and improve their performance.
Everyday Home Use
In daily life, the watch functions as a health monitor and notification centre. It continuously tracks heart rate, blood pressure, blood oxygen, sleep patterns, and body temperature, offering insights into general wellbeing. The Bluetooth call function allows for hands-free conversations, while information push, weather display, and smart reminders keep the user updated. Music control and remote control selfie capabilities add convenience, and the sedentary reminder promotes movement throughout the day.
Benefits and Buying Value

The UM90 offers value by consolidating multiple devices and functions into a single, wearable unit, focusing on practicality and extended use through its design and feature set.
Reuse and Low Maintenance
The device is built for repeated daily use across different contexts. The IP67 rating protects it from sweat and water exposure during exercise or daily chores, supporting its reuse in varied environments. Magnetic charging simplifies power management for the 230mAh battery. The watch's software supports 17 menu languages, including Chinese, English, Korean, Japanese, and several European languages, ensuring it remains usable and relevant for a wide, international user base over time.
Why Choose This Product
Choosing the UM90 provides a direct solution for users seeking a smartwatch that prioritises both communication and in-depth health and sports tracking. Its key differentiators are the direct Bluetooth calling function, the large 1.28-inch screen for clear data display, and the unusually specific range of 24 sports modes. When compared generically to basic fitness trackers, it adds telephony; compared to simpler smartwatches, it offers more granular athletic monitoring. The combination of these features in one device, available in four colour variations (black, black brown, silver black, silver brown), makes it a practical, multi-purpose tool for modern, active lifestyles.
