7 Best Budget Smartwatches Under 100 That Will Blow Your Mind (2026)

If you had told me five years ago that I’d be wearing a device on my wrist that monitors my blood oxygen, tracks my REM sleep, and lets me answer phone calls—all for the price of a decent steak dinner—I would have laughed. Back then, the wearable market was a “you get what you pay for” wasteland. You either dropped $400 on a high-end flagship or settled for a glorified pedometer that looked like it came out of a cereal box.

Top 7 Best Budget Smartwatches Under 100: Expert Analysis

Finding a watch in this price range requires a discerning eye. You want to avoid the “no-name” clones that flood online marketplaces and stick to reputable brands like Amazfit, Xiaomi, and Nothing. Here are the top 7 real products currently dominating the market in 2026.

1. Amazfit Active 2

The Amazfit Active 2 is arguably the gold standard for what a budget wearable should be. It bridges the gap between a simple fitness tracker and a full-featured smartwatch with surprising elegance. In my testing, the 1.75-inch AMOLED display was a standout—punchy, bright enough for the Texas sun, and incredibly responsive. It features the Zepp OS 3.0, which feels much more “grown-up” than previous versions.

• Technical Specifications:

  • Display: 1.75-inch AMOLED, 390 x 450 pixels.

  • Sensors: BioTracker PPG biometric sensor, Accelerometer, Geomagnetic, Ambient light.

  • GPS: Integrated Circularly-polarized GPS antenna (5 satellite positioning systems).

  • Battery: 300 mAh; up to 14 days typical use.

  • Waterproof: 5 ATM.

• Customer Review Analysis: Users frequently praise the “premium feel” for such a low price. The most common feedback mentions the accuracy of the GPS during morning runs. However, some Android users reported that the Zepp app requires a lot of permissions to function correctly.

• Professional Applications: Ideal for casual marathon training and everyday health monitoring.

• Pros:

  • ✅ Stunning AMOLED screen.

  • ✅ Built-in GPS is remarkably accurate.

2. CMF Watch Pro 2

Nothing’s sub-brand, CMF, has disrupted the industry with the CMF Watch Pro 2. This watch is for the minimalist. It doesn’t try to look like an Apple Watch; it has its own circular, industrial aesthetic with interchangeable bezels. If you value design as much as data, this is one of the best budget smartwatches under 100 for your style.

• Technical Specifications:

  • Display: 1.32-inch AMOLED, 466 x 466 pixels, 620 nits brightness.

  • Sensors: Heart rate & SpO2, Accelerometer.

  • GPS: Built-in multi-system GPS.

  • Battery: 305 mAh; 11 days typical use.

  • Waterproof: IP68.

• Customer Review Analysis: Reviewers love the unique UI—it’s monochrome and clean. A recurring complaint is that the vibration motor feels a bit “buzzy” compared to high-end haptics, and the GPS can sometimes take a minute to lock in urban environments.

• Warranty: 1-Year.

• Professional Applications: Great for office environments where you want a sleek, non-distracting notification hub.

• Pros:

  • ✅ Unique, stylish design.

  • ✅ Long battery life (11 days).

  • ✅ Very affordable price point.

• Cons:

  • ❌ IP68 rating is not suitable for swimming.

  • ❌ Software is very basic.

3. Fitbit Inspire 3

For the purists, the Fitbit Inspire 3 remains the king of the “slim” form factor. While it looks more like a band than a watch, its smart features allow it to compete in this category. It’s the go-to for someone who wants to forget they are wearing a device.

• Technical Specifications:

  • Sensors: Optical heart rate, SpO2, Skin temperature, Accelerometer.

• Pros:

  • ✅ Elite-level sleep and stress tracking.

  • ✅ Small and incredibly light.

4. Redmi Watch 4

Xiaomi’s Redmi Watch 4 is a beast of a budget watch. It features a massive 1.97-inch AMOLED display and an aluminum alloy frame—materials you usually only see in watches twice its price. It’s one of the best budget smartwatches under 100 for people who like “big” watches.

Comparison Matrix: Technical Specifications

To help you narrow down the best budget smartwatches under 100, here is a breakdown of how they compare head-to-head.

Performance Metrics: Fitness & Health Accuracy

Not all sensors are created equal. When searching for the best budget smartwatches under 100, accuracy is the most important metric.

Why Buy a Budget Smartwatch? (The Science & The Value)

You might be asking, “Why shouldn’t I just save up for an Apple Watch?” That’s a fair question. However, the best budget smartwatches under 100 offer a specific value proposition that high-end watches can’t match: Focus and Battery Life.

The Battery Life Paradox

High-end watches are essentially tiny smartphones on your wrist. They run complex operating systems (like WatchOS or Wear OS) that are constantly “thinking.” This drains the battery in 1-2 days. Budget watches use “RTOS” (Real-Time Operating Systems). These are much lighter and more efficient, allowing a watch like the Redmi Watch 4 to last three weeks on a single charge. 🔋

How PPG Sensors Work (The Tech Behind the Glass)

Most budget watches use Photoplethysmography (PPG) sensors. These sensors shine a green light into your skin and use a light-sensitive photodiode to measure how much light is reflected back. Because blood absorbs green light, each pulse causes a dip in the reflected light. By measuring these dips, the watch calculates your heart rate. In 2026, even budget sensors have become highly accurate for steady-state cardio (like walking or running).

Table: Benefits of Budget Smartwatches vs. Traditional Watches

The Ultimate Buying Guide: What to Look for in 2026

When you’re hunting for the best budget smartwatches under 100, it’s easy to get distracted by flashy marketing. I always tell people to focus on these four pillars:

1. Display: AMOLED vs. LCD

If you can find an AMOLED screen (like on the CMF Watch Pro 2), take it. AMOLED screens have individual pixels that turn off completely for true blacks, which also enables the “Always-On Display” (AOD) feature. LCDs are cheaper but require a backlight, which looks slightly grey in the dark and consumes more power for AOD.

2. GPS: Built-in vs. Connected

• Built-in GPS: The watch has its own antenna. You can leave your phone at home and still track your run.

• Connected GPS: The watch “borrows” the GPS from your phone via Bluetooth. If you don’t bring your phone, you don’t get a map.

  If you’re a runner, built-in GPS is a non-negotiable requirement for the best budget smartwatches under 100.

3. The Ecosystem (The App)

A watch is only as good as the app on your phone.

• Zepp (Amazfit): Very detailed, integrates with Strava and Apple Health.

• Mi Fitness (Xiaomi): Clean, but sometimes has sync delays.

• Fitbit App: The most user-friendly, but many features (like “Daily Readiness”) are hidden behind a monthly subscription.

4. Durability and Water Resistance

Look for “5 ATM” if you want to swim. This means it can handle pressure equivalent to 50 meters of depth. “IP68” is fine for a shower or rain, but I wouldn’t take it in the pool.
