## Description

【2025 】This Military Smart Watch is specifically designed for professional outdoor sports enthusiasts. It is waterproof, shockproof, and dustproof, making it suitable for any rugged environment.

Review: All the basic stuff you need in your first smart watch. Good battery life.
Review: Its a good basic health watch for the price. Hanfit app is a bit overbearing but useful and its software will interact with Google fit. Fyi It doesn't provide blood pressure though (not sure that's a bad thing in my experience, most aren't very accurate). As a very basic introduction into health/smart watch its not a bad purchase. Its fairly large face makes it easy to see and read, for me battery life is rather good at 5 days between recharge. I have android so it can play music, answer calls, and give basic notifications, and has a rather large selection of customizable options. I will say that its internal speaker/mic definitely leaves a bit to be desired (reasonably loud but sound quality is low for calls/music) but for its price compared to the price's of big name brand smart watchs it does a pretty decent job for the price. May sound like im kinda knocking it down on technicalities but if this one breaks I'd buy it again based on its price
