Walkie-Talkie, 5-Level Flashlight & Dual-Band 6-System GNSS in a Rugged Build
The KOSPET TANK T4C is a smartwatch built for job sites and outdoor field work where standard consumer watches are not adequate. The two features that distinguish it from typical rugged watches are the built-in short-range walkie-talkie and the integrated 5-level LED flashlight — both are genuine field tools rather than marketing additions. The walkie-talkie connects up to four T4C units simultaneously within a 40-metre range via the Apexmove app, enabling direct voice communication on a job site without reaching for a phone. The flashlight runs up to 5 hours at full brightness across five adjustable output levels.
The build quality matches the field positioning: stainless steel bezel, zinc alloy frame, Gorilla Glass 3, and 5 ATM + IP69K certification covering submersion and high-pressure water jets. The 1.5″ AMOLED at 1,000 nits peak brightness stays readable in direct sunlight — a practical necessity for outdoor use that most 300–600 nit displays fail at. Dual-band 6-system GNSS covers GPS, GLONASS, Galileo, BeiDou, QZSS, and NavIC for accurate positioning in forests, canyons, and urban canyons where single-band GPS drifts.
The GH3026-4PD optical sensor handles 24/7 heart rate, SpO2, stress, and sleep monitoring, with a 60-second one-tap check that reads all four vitals at once. At 500mAh with a pure cobalt cell the battery covers 12–15 days of typical use, dropping to around 21 hours under continuous GPS. The 22mm quick-release silicone strap is replaceable with any standard 22mm band.

Frequently Asked Questions
How does the built-in walkie-talkie work?
The walkie-talkie function connects up to four T4C units directly within a 40-metre range via the Apexmove app platform. It enables direct voice communication between team members without picking up a phone — designed for job sites and field environments where hands-free group communication is practical. All units must be T4C models running Apexmove.
What is the difference between the T4C and the TANK T4?
The T4C adds the walkie-talkie and 5-level flashlight that the T4 does not have, and is lighter at 60.7g versus approximately 77g. The T4 has a higher water rating at 10 ATM (45m dive-rated) versus the T4C's 5 ATM, a full stainless steel MIL-STD-810H body, 32GB internal storage, offline downloadable maps, and a 2-year warranty versus 1 year. Choose the T4C for job-site field tools; choose the T4 for diving, extreme environments, and offline mapping.
Does the 6-system GNSS work without a phone?
Yes — the dual-band GNSS module is built into the watch and operates standalone. It tracks position using GPS, GLONASS, Galileo, BeiDou, QZSS, and NavIC simultaneously for accurate positioning in challenging environments including forests, canyons, and dense urban areas. Route data syncs to Strava and Apple Health when reconnected to the phone.
