Our Review

Design & Build

The Military Smart Watch S10 makes a strong first impression with its rugged construction. The metal casing and materials meet military-grade standards for heat, cold, moisture, and dust resistance, making it suitable for outdoor adventures and demanding environments. At 110g, it's lightweight enough for all-day wear without feeling cumbersome on the wrist.

The 1.39-inch HD touchscreen delivers vibrant colors and responsive touch controls, which is remarkable at this price point. The display offers four brightness levels for visibility in various lighting conditions, and the customizable watch faces add a personal touch. You can upload your own photos, transforming the watch into something uniquely yours.

Build quality feels solid for a budget device, though don't expect the premium materials found on watches costing ten times more. The IP68 waterproof rating means you can wear it in the rain or shower, but it's explicitly not suitable for swimming, diving, saunas, or hot water exposure—a limitation worth noting for water sports enthusiasts.

Performance & Features

Where the S10 truly shines is its versatility. The 110 sports modes cover an impressive range of activities from mainstream options like running and cycling to niche pursuits like rock climbing, skiing, and boxing. During workouts, the watch tracks steps, distance, calories, and exercise time, providing useful data to help monitor your progress.

The call functionality works surprisingly well for a budget smartwatch. The 60-decibel speaker delivers clear audio, and the noise-canceling microphone ensures decent call quality. You can sync frequently used contacts through the GloryFit app, making it convenient to take calls without reaching for your phone.

Smart notifications are comprehensive once connected via Bluetooth, supporting WhatsApp, Facebook, Twitter, Instagram, LinkedIn, and more. The watch also includes practical features like music control, camera remote, voice assistant access, weather forecasts, sedentary reminders, stopwatch, alarm clock, calculator, and phone finder.

Health Tracking

The fitness tracking suite includes heart rate monitoring, sleep tracking, and pedometer functionality. While the manufacturer correctly notes this data is for reference only and not medical-grade, it provides useful insights into daily activity levels and sleep patterns. The health metrics help you understand trends and adjust habits accordingly, which is all most casual users need.

Battery Life

Battery performance is a standout feature. The 300mAh battery delivers up to 10 days of normal use and approximately 30 days on standby. Charging takes around 2 hours, which is reasonable. This longevity makes the S10 ideal for travel and outdoor activities where frequent charging isn't convenient. Actual battery life will vary based on usage patterns—heavy use of call features and continuous heart rate monitoring will drain it faster—but even conservative estimates suggest you'll easily get a week between charges.

Value

At £15.99, the Military Smart Watch S10 represents extraordinary value. You're getting features typically found on watches costing £50-100 or more, including call functionality, extensive sports modes, and solid battery life. The build quality, while not premium, exceeds expectations for the price.

The watch supports Android 5.0/iOS 9.0 and above, making it compatible with virtually all modern smartphones. The unknown software update timeline is a concern for long-term support, but at this price, expectations should be realistic. This isn't a device you'll keep for five years, but it'll serve well for a year or two of daily use.

Who Is This For?

This smartwatch is ideal for budget-conscious fitness enthusiasts who want comprehensive activity tracking without spending big. It's perfect for students, casual exercisers, or anyone looking for a backup smartwatch for outdoor activities where they don't want to risk damaging an expensive device. If you need basic fitness tracking, call functionality, and smart notifications at an unbeatable price, the S10 delivers.

Our Verdict

The Military Smart Watch S10 is a remarkable achievement at £15.99, offering features and build quality that shame many watches costing three or four times more. While it can't match premium smartwatches in refinement or long-term software support, it excels at delivering practical fitness tracking and smart features at an accessible price. For budget buyers or those seeking a rugged backup watch, this is an easy recommendation.
