Highlight
Core Feature
Heatstroke Warning
● Uses high-precision sensors (±0.1°C) to continuously track both ambient temperature and body surface temperature.
● Instantly alerts when the risk of heatstroke is detected, giving users time to rest, hydrate, and stay safe.
● More reliable than relying on experience alone—helping users and teams prevent accidents before they happen.
High-accuracy watch
● Daily time deviation is less than one second, ensuring users always keep accurate track of time.
● Especially useful in special work environments where timing is critical for breaks, shift changes, or safety reminders.
● Reliable precision means teams can coordinate tasks smoothly and reduce risks caused by timing errors.
● Offers the same precision and reliability for managing your daily schedule.
Reliable Performance
● Certified with IP67 dust and water resistance, proven to withstand sweat, rain, and tough site conditions.
● Backed by strict durability tests, ensuring the device works steadily in 90% of daily and industrial scenarios.
● Users can trust it won’t fail on the job, and managers gain peace of mind knowing equipment is dependable.
Lightweight Comfort
● Breathable strap design keeps the device cool and comfortable, even during long hours of work.
● So light and simple that users barely notice they’re wearing it.
