Garmin Instinct® 3 Smartwatch 45mm Solar Tactical - (Black)

Elite Stealth. Relentless Power. The Instinct® 3 Solar Tactical (45 mm) is the standard-sized evolution of Garmin’s most rugged series, launched in 2025. This model bridges the gap between the compact 40 mm and the oversized 50 mm, providing a balanced fit without sacrificing mission-critical tools. With a metal-reinforced bezel and a 5x increase in solar efficiency over its predecessor, this watch is designed to stay off-grid indefinitely while providing elite tactical utility.


Key Highlights
Unlimited Solar Battery: The new, high-efficiency Power Glass™ lens provides unlimited battery life in smartwatch mode and up to 130 hours in GPS mode (with solar), ensuring you never have to worry about a charging cable in the field.

Stealth & Security: Features a dedicated Stealth Mode to cut all wireless communication and GPS logging, plus a Kill Switch that wipes all user data and memory in seconds for sensitive operations.

Applied Ballistics® Built-in: Preloaded with the Applied Ballistics® Ultralight solver for long-range shooting solutions (requires a one-time unlock fee for full ballistic capabilities).

Night Vision Compatibility: The high-contrast, monochrome display features a dedicated NVG Mode that reduces brightness and allows the screen to be read clearly through night vision goggles.

Multi-LED Flashlight: An integrated flashlight with variable intensities. The Tactical Edition includes a Green Light mode, which is superior to red for preserving night vision and reading topographical maps in total darkness.


Mission-Ready Navigation: Multi-band GNSS with SatIQ™ technology offers pinpoint positional accuracy while the watch automatically manages power consumption. Features dual-position GPS formatting (MGRS/UTM).


New Training Intelligence: Includes Garmin’s latest Training Readiness, Sleep Coach, and Rucking Activity profile, allowing you to track the specific physical toll of weighted field marches.
