How to choose the right one
Check the size first
You should start by looking at the physical dimensions. The Garmin HRM 600 measures 2.7 inches wide, making it a dedicated monitor rather than a standard wristwatch. If you prefer a wearable device, consider the Forerunner 55 at 1.65 inches wide. The Forerunner 70 is slightly wider at 1.68 inches. The Instinct E is compact at 1.57 inches. Verify the width and height match your wrist size. A larger device may feel bulky during sleep or daily wear. Ensure the length fits your strap preferences for a secure fit.
Compare the weight
Weight affects comfort during long workouts. The Garmin HRM 600 weighs 2.2 ounces, which is heavier than most watches. This extra mass may suit those who want a robust feel. The Forerunner 55 is lighter at 1.31 ounces. The Forerunner 70 weighs 1.4 ounces. The Instinct E is also 1.45 ounces. Lighter models reduce fatigue during running or swimming. Heavier models might stay in place better during high-impact activities. Choose based on how much weight you can tolerate on your wrist all day.
Look at the display
Screen type changes how you read data. The Forerunner 70 features an AMOLED display. This offers vibrant clarity for beginners who want sharp visuals. The Forerunner 55 has an always-on display, which is practical for quick glances without raising your wrist. The HRM 600 lacks a traditional watch face, serving as a sensor. Decide if you need a bright screen or just essential metrics. AMOLED screens consume more battery. Always-on displays are convenient but may drain power faster. Pick the screen that matches your visibility needs.
Match connectivity needs
Connectivity determines how data travels. The Forerunner 55 includes GPS for tracking location without a phone. The Instinct Esports Edition also has GPS for gaming sessions. The HRM 600 relies on a chest strap design, not wrist-based GPS. If you run without a phone, ensure the watch has built-in GPS. The HRM 600 requires a compatible Garmin watch to store data. Check if your existing device supports the monitor. For standalone tracking, choose a model with integrated GPS and clear signal specs.
Consider the activity
Your main sport dictates the best specs. Runners benefit from the HRM 600 for precise heart rate data. Swimmers also find this monitor reliable. Beginners should look at the Forerunner 55 for basic GPS and heart rate tracking. Outdoor enthusiasts need the Instinct E for its rugged build and compact case. Gamers might choose the Instinct Esports Edition for health tracking during play. Align the device with your primary activity. Each model targets a specific use case. Ensure the tracked metrics match your training goals for accurate results.
