Buying Guide

How to Buy a Smartwatch

This quick guide helps you pick the right smartwatch by outlining the most important buying factors, types available, key specs to check, where to buy, common mistakes to avoid, and fast expert tips to act on now.

Key factors to consider

Consider these core points before you buy.
  • Purpose: Do you want general wellness tracking, running and outdoor navigation, dive support, or full smartphone features like calls and apps?
  • Phone compatibility: Verify it works well with your phone OS and app ecosystem.
  • Battery life: Ranges from about 18 to 24 hours on many full-feature watches to multiple days or even weeks on battery-optimized models. Some advanced sport watches list up to 29 days in smartwatch mode.
  • Durability and water resistance: Ratings vary from basic splash resistance and 3ATM to 50m and dive-rated models. Match rating to your activity.
  • Size and comfort: Case sizes in this set run roughly 40mm to 51mm and displays from about 1.32 to 1.4 inches. Try on for fit when possible.
  • Budget: Prices can range from under $50 for basic options up to near $1,000 for premium multisport units. Decide what features justify your spend.

Types and important features to check

Know the main categories and the specs that matter.
  • Basic fitness trackers: Affordable, long battery life, step and heart rate tracking, simple notifications.
  • Everyday smartwatches: Bright AMOLED displays, phone notifications, call and music control, sleep tracking and more advanced health metrics.
  • Multisport and adventure watches: Built for GPS accuracy, multisport modes, durable materials, long battery life, sometimes built-in flashlight or dive support.
  • Dive-rated or technical watches: Designed for scuba and apnea with leakproof controls and deeper water ratings.
  • Key specs to verify: display type (AMOLED for clarity), glass and bezel materials (sapphire or hardened glass and metal or titanium bezels), GPS type (multi-band or phone-assisted), sensors (heart rate, SpO2, ECG availability), calling capability (speaker and mic), and battery charge times and fast-charge claims.
  • Remember sensor limitations: health metrics are useful for trends and training but are not a substitute for medical devices.

Where to buy and common mistakes to avoid

Buy online for price comparisons and quick delivery or visit a store to try sizes and straps. When buying online check seller reputation, warranty length, return policy, and shipping options. Some listings show free shipping and in-stock status while premium items may be low in stock.
  • Do not buy solely on price. Very cheap units may lack accurate sensors, reliable software updates, and good support.
  • Do not assume every model supports all features. Confirm phone compatibility, GPS vs phone-based tracking, and whether advanced features require a companion app.
  • Do not ignore warranty and return windows. Expensive units usually justify buying from authorized sellers or adding extended coverage.
  • Avoid relying on single reviews. Look for consistent feedback on battery life and sensor accuracy.

Expert tips and quick recommendations

Actionable tips to finalize your choice quickly.
  • Pick battery life that matches your routine. If you run long GPS workouts, prioritize longer GPS mode runtime or quick charging ability.
  • If you want strong outdoor navigation, choose a unit with multi-band GPS and navigation features, not just phone-dependent GPS.
  • For everyday wear pick AMOLED plus a durable glass if you care about screen clarity and scratch resistance.
  • Choose water rating based on activity. 3ATM is fine for showers and pools. Dive or scuba users need higher, dive-rated watches.
  • Try bands and case size in person if possible. A 40 to 42mm case suits many wrists while 51mm is more for large wrists and heavy use.
  • Buy from authorized channels when buying premium models. For budget units, prioritize sellers with easy returns and clear warranty terms.

Final Thoughts

Decide first what matters most to you: battery life, sports GPS, health sensors, durability, or price. Match that priority to a category, confirm phone compatibility and warranty, then buy from a reputable seller. That approach gets you a smartwatch you will actually use and enjoy.
