zhizhi Military Smart Watch Review – Worth the Hype?

Quick Verdict

The zhizhi military smart watch delivers a surprising amount of functionality for under $50. Bluetooth calling, 120+ sports modes and IP68 waterproofing make it a credible daily driver for anyone who wants fitness tracking without flagship pricing. Two weeks of real-world use showed me that it's not a replacement for a Garmin or Apple Watch — but as a do-everything starter smartwatch, it earns a solid 7.8 / 10. Keep reading before you buy.

What Is the zhizhi Military Smart Watch?

Right out of the box, the zhizhi military smart watch looks more expensive than its price tag suggests. The 2.06-inch display sits behind a slightly raised bezel, and the matte-black case gives it a utilitarian edge that stands out among the sea of rounded smartwatch clones on Amazon. It ships with two straps — a silicone sport band and a slightly more refined option — so you can swap looks depending on whether you're heading to the gym or a coffee meeting.

Under the hood, this is essentially a fitness tracker with a large screen and calling capability. The companion app (available on both iOS and Android) handles setup in under five minutes. Notifications, call handling, workout logging and sleep tracking all live there. The watch itself runs a custom OS that stays snappy for basic interactions, though you'll notice slight lag when scrolling through longer menus.

Hands-On Review

I unboxed this on a Tuesday morning and wore it through a full week before forming any opinions. First impression: the display is genuinely crisp. 466×466 on a 2-inch screen looks sharper than I expected at this price, and the IPS full-view tech means you get decent visibility from an angle — useful when you're glancing down mid-stride on a run.

The Bluetooth calling feature surprised me the most. I spend about 90 minutes a week on conference calls while walking the neighborhood, and the zhizhi military smart watch let me stay in the conversation without stopping to dig for my phone. Voice came through clearly enough for my end — the speaker on the watch itself is fine for listening, though anyone on the other end of a longer call will notice it's coming from a tiny wrist-mounted device. Short, functional calls only, in my experience.

What surprised me was the heart rate data during a morning interval session on day three. I wore it alongside my usual chest strap, and the zhizhi read consistently 8–12 bpm higher during high-intensity bursts. Steady-state cardio was closer, maybe 4–5 bpm off. That's typical for optical sensors at this price, but it's worth knowing if you're training by heart rate zone. I wouldn't rely on it for precision intervals, but for general activity tracking it's fine.

Battery life was honest. With notifications on, two workouts and about 30 minutes of Bluetooth calling per day, I got just over six days before the low-battery warning. That's close to the stated seven days. Charging via the magnetic puck took about an hour and 40 minutes from empty — not the fastest, but you won't be doing it daily.

Who Should Buy It?

You're looking for a feature-packed smartwatch on a budget and don't need medical-grade accuracy. If you want Bluetooth calling, fitness tracking and a big display without spending $200+, this fits. It's also a good choice if you like switching watch faces — the 250+ online options and photo upload feature keep things fresh.

Skip this if you're a serious runner or cyclist who needs built-in GPS and precise pace data. The zhizhi military smart watch is also not for you if you want seamless Apple Health or Google Fit integration — the proprietary app works, but the sync isn't as polished as what you'd get from Wear OS or watchOS.

Alternatives Worth Considering

Samsung Galaxy Watch 6 — If your budget stretches further, Samsung's offering delivers GPS on the wrist, sharper OLED display and far more polished software. It's three to four times the price, but the experience gap is real.

Amazfit Bip 5 — Huami's budget line offers longer battery life and built-in GPS at a similar price point. The display isn't as sharp, but the health tracking algorithms are more refined.

Fitbit Inspire 3 — If pure health and sleep tracking accuracy is your priority and you don't care about calling or voice assistants, Fitbit's slim band-style tracker is a cleaner, simpler option at a comparable price.

Final Verdict

The zhizhi military smart watch punches well above its weight for the price. Bluetooth calling, a vivid 2.06-inch display, 120+ sports modes and IP68 waterproofing add up to a package that would have cost double just a few years ago. It's not going to replace a dedicated sports watch or a flagship smartwatch, but as a daily fitness companion that can handle calls and notifications without draining your phone battery, it holds its ground. Battery life is honest, the two included straps add versatility, and the 250+ watch faces mean it won't feel boring after a month. Will I keep wearing it? Yes — with the caveat that I'll still reach for my chest strap on interval days.
