• Strap: The strap material is crucial for swimming. Silicone is popular due to its water resistance, quick-drying properties, and comfort. Nylon and specialized rubber straps are also good options. Leather or metal link bracelets are generally less suitable for prolonged water exposure. Look for straps that are easily replaceable and secure.
• Water and Dust Resistance: This is paramount for any swimming smartwatch. You’ll encounter two main ratings:
  • IP (Ingress Protection) Rating: This indicates protection against solids (dust) and liquids (water). An IP68 rating means it’s dust-tight and can withstand immersion in water under specific conditions (e.g., 1.5 meters for 30 minutes). While good for splashes and accidental immersion, IP ratings are not designed for sustained swimming or high-impact water activities.
  • ATM (Atmosphere) Rating: This is the most relevant rating for swimmers. It measures static pressure resistance.
    • 3 ATM (30 meters): Suitable for splashes and rain, but not for swimming or showering.
    • 5 ATM (50 meters): The minimum recommended rating for showering, surface swimming, and shallow water activities. This level can handle the pressures of arm movement during swimming.
    • 10 ATM (100 meters) or higher: Ideal for competitive swimming, high-impact water sports (like surfing or whitewater rafting), and even recreational diving. Watches like the Garmin Fenix series often boast 10 ATM or higher. Always prioritize an ATM rating of at least 5 ATM for swimming.

Display

A clear and visible display is essential for checking your stats mid-swim.
