EIGIIS S320B Rugged Military Smartwatch

Built to endure, with smart health tracking

The S320B combines a military-grade chassis with practical features you rely on in the field. It’s rated at 3 ATM for water resistance, meaning you can wash off sweat, splash through rain, and even swim with it. The 2.02-inch square TFT display stays legible in bright sun and dim environments thanks to tempered glass protection and an alloy case designed to withstand shocks and impacts from outdoor activities.

• Military-standard build tested for wide temperature changes (-40°C to 70°C) and impact resilience
• 3 ATM water resistance for swimming and water-related training
• Compass and LED flashlight for navigation and low-light tasks
• Silicone band with quick-detach design for easy swap and all-day comfort
• Bluetooth 5.2 with FitCloudPro app compatibility for seamless syncing
• Heart rate, SpO2 (blood oxygen), and blood pressure monitoring for comprehensive health tracking

What it tracks and how it helps

Designed for active lifestyles, the S320B tracks steps, distance, and calories to help you hit daily movement goals. The sleep tracker provides insights into your rest quality, while the multi-sensor setup (heart rate, SpO2, and BP) supports a more complete view of your wellness over time. Use the built-in activity modes to monitor workouts, runs, and outdoor adventures with real-time feedback on your wrist.

Smart features that keep you connected

• Call and message reminders with quick access to dial and answer calls

Battery life and charging

With a robust 400 mAh battery, you can expect 5–7 days of normal use and up to 15 days in standby. A full magnetic charging cycle typically takes about 2 hours, so you’ll spend less time plugged in and more time on the move.

Who this is for

• Outdoor enthusiasts and outdoor professionals who need a durable watch that won’t quit in demanding environments
• Athletes and trainees who want ongoing health metrics, including heart rate, SpO2, and BP, during workouts
• Anyone who prioritizes reliable notifications, music and camera controls, and long battery life on the go

Compared to typical fitness watches

The S320B stands out with a rugged, military-grade design, extensive environmental testing, and the combination of heart rate, SpO2, and blood pressure monitoring on a single wearable. Its 3 ATM rating and tough build make it a more capable companion for swimming, snow, and uneven terrain, while its long battery life reduces the need for frequent recharging during extended trips.

Whether you’re planning a rugged trek, a seaside workout, or late-night training sessions, the EIGIIS S320B is built to accompany you with dependable performance, precise health insight, and practical smart features that mesh with your daily routine.
