Rugged Tech Meets Modern Connectivity: Tank S3 Pro Military Smartwatch Launches with Massive Battery and Phone Calls


The demand for rugged wearables that blend toughness with smart features is soaring, and Rogbid’s latest release is poised to dominate the market. Meet the Tank S3 Pro, a military-grade smartwatch engineered for adventurers, first responders, and outdoor enthusiasts who refuse to compromise on durability or functionality. Boasting a massive battery, phone call capabilities, and a design that laughs in the face of extreme conditions, this device is redefining what a rugged smartwatch can do.

Built to Survive: Military-Grade Durability
The Tank S3 Pro isn’t just rugged—it’s virtually indestructible. Built to meet the MIL-STD-810H military standard, it withstands drops, shocks, extreme temperatures, and vibrations. Its reinforced stainless steel frame and IP68 rating ensure resistance to dust, dirt, and submersion in water up to 1.5 meters for 30 minutes. Whether you’re scaling a mountain, navigating a desert, or working in a high-impact job, this watch is designed to keep up.

A Battery That Outlasts the Competition
Powering the Tank S3 Pro is a 680mAh battery, a standout feature in the rugged smartwatch category. Rogbid claims up to 30 days on standby or 10 days of regular use, including GPS tracking and health monitoring. Even with the always-on display and Bluetooth calling enabled, users can expect a week of uninterrupted performance. For those venturing off-grid, a power-saving mode extends longevity further.

Stay Connected Anywhere: Built-In Phone Calls
One of the Tank S3 Pro’s most innovative features is its Bluetooth calling capability. Equipped with a built-in microphone and speaker, users can make or answer calls directly from their wrist—no smartphone required. This rare feature in rugged wearables ensures connectivity during emergencies or hands-free convenience during adventures.
