What to know before buying

Listing details to confirm

The listing identifies a 0.9-inch OLED/AMOLED screen, while the title and product description call it a solar-charged display. Its battery table lists 28 days, whereas the solar claim says unlimited only in smartwatch mode with all-day wear and 3 hours per day outside in 50,000 lux. Customer feedback is mixed on solar performance and connectivity, so confirm the desired display and operating-mode expectations before buying. The preloaded Applied Ballistics solver requires a one-time purchase through the AB Quantum mobile app. Health estimates are not medical measurements, and Pulse Ox is not available in all countries.

Frequently asked questions

Does solar charging mean unlimited battery life?

The listing makes that claim only for smartwatch mode with all-day wear and 3 hours per day outside in 50,000 lux conditions. It also lists a 28-day battery life, so treat the solar statement as conditional rather than a general runtime.

What tactical features are listed?

The listing names stealth mode, kill switch, waypoint projection, jumpmaster activity, dual-position GPS format, night-vision-goggle compatibility and a rucking activity.

Is Applied Ballistics included at no extra cost?

The solver is described as preloaded, but using it requires a one-time purchase through the AB Quantum mobile app.

Can it be used for medical monitoring?

It offers health estimates including wrist-based heart rate, sleep monitoring and Pulse Ox, but the listing says it is not a medical device. Pulse Ox is not available in all countries.
