Amazfit T-Rex 3 vs Gabb Watch 3e: which should you buy?
Get the Amazfit T-Rex 3. It is a tough outdoor watch with dual-band GPS, free offline maps and weeks of battery, and for an adult it does far more than the Gabb Watch 3e. The Gabb is a kids watch with its own phone number, made for a child and a watchful parent.
Who should get the Gabb Watch 3e
Get the Gabb if the watch is for a child. It is a first phone a kid wears, with its own number for calls and texts to contacts a parent approves, and Safe Zone alerts that tell a parent when the child leaves a set place. It works without a phone, and parents manage it in the MyGabb app on an iPhone or an Android phone. The T-Rex is not built for that job.
The differences that matter
Battery is the clearest split. Amazfit rates the T-Rex 3 at up to 27 days of typical use and up to 42 hours of accurate GPS. Gabb rates its watch at 14 to 18 hours of normal use, so the Gabb goes on the charger every night.
Water and build come next. Amazfit rates the T-Rex 3 10 ATM and certified for freediving to 45 m. The Gabb is water resistant but not for swimming.
Navigation is the third. Dual-band GPS across six satellite systems keeps your position on a long hike, and offline maps show you the way.
On an iPhone the T-Rex works with some features missing: quick replies to calls work with Android only.
Price and value
The Amazfit T-Rex 3 costs $270.01 (checked Nov. 15, 2026) and the Gabb Watch 3e costs $209.99 (checked Nov. 15, 2026). The Gabb Watch 3e is cheaper by $60.
Budget for the service too: the Gabb needs a monthly Gabb plan and an activation fee on top of the watch. The T-Rex needs no plan. For your own hikes and dives, get the T-Rex.
