This rugged smartwatch is built for the outdoors — score the Amazfit T-Rex 3 for its best-ever price
SAVE $90: As of July 18, the Amazfit T-Rex 3 is on sale for $189.99 at Amazon — that’s 32% off its original price of $279.99.
Fitness fanatics seeking a smartwatch that’s a little cheaper than the big brands like Apple or Samsung have got a strong alternative on offer in the Amazfit T-Rex 3.
As of July 18, the Amazfit T-Rex 3 Smartwatch is on sale for $189.99 at Amazon — a 32% reduction from its standard $279.99 — its lowest price ever since launching last year (according to the camelcamelcamel). If you’ve been looking for a smartwatch that’s as tough as your trail shoes, this deal might be what gets you off the fence.
This rugged-looking 48mm watch is designed for the outdoors, with a peak brightness of 2000 nits on its AMOLED display for clear map and workout visibility even under harsh sunlight. It’s also ready to handle some serious wear and tear, thanks to a 316L stainless steel bezel, freediving support up to 147 feet, and tested durability across extreme temperatures from -22 degrees farenheight to 158 degrees.
The battery life is another win here — the T-Rex 3 can go up to 27 days on a single charge with regular use or 180 hours in GPS mode. That’s a huge plus for anyone planning multi-day hikes or extended backcountry adventures. Speaking of GPS: with dual-band GPS, six satellite systems, and offline global maps, the T-Rex 3 offers precision location tracking even when you're off the grid. You’ll also get turn-by-turn navigation, a huge help when trails start to blur together.
For fitness junkies, this smartwatch covers a ton of ground with 170+ sport modes, AI-driven training plans, and real-time metrics across everything from hiking to surfing.
Alternatively, the Samsung Galaxy Watch 7 is still on sale for $159.99 at Amazon.
