Is the Garmin Forerunner 45 Worth Buying?

The Garmin Forerunner 45 remains one of the most compelling entry-level sports watches on the market in 2024. At its price point, it delivers impressive training capabilities, reliable health monitoring, and exceptional battery life that outperforms many competitors. Whether you’re a casual jogger or someone training for their first 5K, this watch offers genuine value without forcing you to choose between features and affordability.

How Does the Garmin Forerunner 45 Look and Feel?

Garmin’s design philosophy emphasizes function over fashion, and the Forerunner 45 exemplifies this approach perfectly. The watch features a compact, understated 39.5mm case with a 1.04-inch monochrome LCD display. The 240×240 pixel resolution isn’t flashy, but it’s remarkably crisp and readable in bright sunlight—a genuine advantage over AMOLED screens that can wash out in daylight.

The silicone watch band feels durable and lightweight at just 38.5 grams. The buttons on the right side have satisfying tactile feedback, and the overall build quality feels premium despite the budget-friendly price. The watch is water-resistant to 50 meters, making it safe for swimming and snorkeling but not diving. It’s available in black, white, and red colorways.

What Health Features Does the Garmin Forerunner 45 Offer?

The Forerunner 45 integrates a reliable optical heart rate sensor for continuous monitoring throughout the day and during workouts. You’ll get heart rate zones, resting heart rate tracking, and heart rate variability measurements to assess training stress and recovery status. The watch also monitors sleep quality with automatic sleep detection and provides detailed breakdowns of light, deep, and REM sleep phases.

Daily activity tracking includes step counting via the accelerometer, calories burned estimation, and an intensity minutes metric that Garmin calls “Intensity Minutes.” The watch lacks more advanced sensors like a blood oxygen (SpO2) sensor or ECG sensor, which is notable for the price category. However, it does track your stress levels using heart rate variability data, offering guided breathing exercises when stress levels peak.

How Long Does the Garmin Forerunner 45 Battery Last?

This is where the Forerunner 45 genuinely excels. The watch delivers an impressive seven days of battery life with typical use, or up to five days if you’re running with GPS enabled daily. Garmin achieves this through the efficient monochrome display and power-conscious Garmin OS. Compared to smartwatches using Apple Watch or Wear OS, this longevity is remarkable. You’ll charge this watch roughly once per week, compared to the daily charging required by most competitors.

What Smart Features Does the Garmin Forerunner 45 Have?

The Forerunner 45 provides smart notifications for incoming calls, texts, and app alerts directly to your wrist. You can view weather information, control music playback on your paired smartphone, and set silent alarms. However, there’s no contactless payment system like Apple Pay, Google Pay, or Garmin Pay, which may disappoint those seeking complete smartphone replacement functionality.

The watch connects via Bluetooth to the Garmin Connect mobile app, available on both iOS and Android app stores. The app ecosystem is robust, allowing you to browse training plans and download widgets, though it’s not as extensive as Apple’s or Samsung’s ecosystems. You can respond to notifications with quick replies on Android devices but not iOS.

How Well Does the Garmin Forerunner 45 Track Sports?

The Forerunner 45 excels at run tracking with dedicated running profiles for outdoor running, trail running, and treadmill modes. The GPS receiver with GLONASS support provides accurate distance and pace measurements, typically within 1-2 percent accuracy in real-world conditions. For cyclists, there’s a cycling profile that leverages the accelerometer to detect cadence.

The watch offers 11 indoor and outdoor sport modes covering swimming, strength training, yoga, and more. During workouts, you’ll see real-time metrics including pace, heart rate zones, cadence, and elevation data courtesy of the barometric altimeter. The touch-and-hold training alerts warn you if you’re drifting outside your target heart rate zone, which proves invaluable for structured interval workouts.

Pros

• Outstanding seven-day battery life crushes competitors like the Apple Watch Series 9, which requires daily charging
• Exceptional value at under $200, delivering features found on watches costing twice as much
• Highly accurate GPS with GLONASS and reliable optical heart rate sensor for consistent health monitoring
• Monochrome display offers superior sunlight visibility and contributes to remarkable battery efficiency
• Intuitive interface and buttons-based navigation require no learning curve, making it perfect for newcomers to sports watches

Cons

• No blood oxygen (SpO2) sensor or ECG sensor limits health tracking depth compared to mid-range competitors
• Absence of contactless payment (Garmin Pay) eliminates a key convenience feature found on most modern smartwatches
• Monochrome display, while practical, feels dated compared to vibrant AMOLED screens on rivals like the Samsung Galaxy Watch

Who Should Buy the Garmin Forerunner 45?

Beginners entering the running world will find this watch immensely helpful without overwhelming complexity. Casual fitness enthusiasts who prioritize battery life over constant screen updates should absolutely consider this model. Budget-conscious athletes unwilling to sacrifice core features for affordability have found their match. Weekend warriors and joggers training for distance events benefit from the reliable GPS and heart rate monitoring. Anyone checking out the best Garmin watches for value will consistently land on the Forerunner 45.

Who Should Skip the Garmin Forerunner 45?

Serious endurance athletes requiring extensive sensor data should explore higher-end Garmin models with altimeters, barometric pressure sensors, and temperature sensors. Users demanding a color display or always-on screen should look elsewhere. Anyone requiring contactless payments or comprehensive smartwatch features beyond fitness tracking will find this watch limiting. If you’re comparing Apple Watch vs Samsung Galaxy Watch, those ecosystems offer deeper integration but sacrifice the battery life advantage the Forerunner 45 provides.

How Does the Garmin Forerunner 45 Compare to Competitors?

Against the Apple Watch SE, the Forerunner 45 sacrifices a color display and app ecosystem for dramatically superior battery life and lower price. The Apple Watch requires daily charging and costs $249 versus the Forerunner 45’s $199 price tag. Compared to the Samsung Galaxy Watch 4, Garmin’s entry-level option offers simpler operation and better longevity, though Samsung delivers more sophisticated health features and wireless payments through Samsung Pay.

Final Verdict

The Garmin Forerunner 45 represents outstanding value in the sports watch category. It delivers essential training features, dependable health monitoring, and battery life that makes weekly charging feel like a luxury rather than a chore. The monochrome display proves practical rather than limiting, and the straightforward interface welcomes newcomers to the wearables world. While it lacks some advanced sensors and modern aesthetics, these omissions enable the aggressive pricing and exceptional efficiency.

For runners, casual athletes, and fitness enthusiasts seeking reliability without complexity, the Forerunner 45 is a genuine recommendation. It won’t impress tech enthusiasts chasing the latest features, but it will consistently perform day after day, week after week, requiring minimal fussing and maximum training insight.

Final Score: 8.2/10
