Buying Guide: What to Look for in a Swim Tracker Watch
nnnnWaterproof Rating and Depth
nnnnNot all water-resistant watches are suitable for swimming. Look for a rating of at least 3ATM (30 meters) for pool swimming, or 5ATM (50 meters) for open water and more intense use. The EURANS watch boasts IP68 waterproofing, which is ideal for pool laps and daily splashes. The Enfit offers 3ATM, good for shallow swimming, while the moutarlier features 5ATM (50m) for serious swimmers. For a deeper dive into waterproof watches, see our best watches for swimming article.
nnnnGPS Tracking for Open Water
nnnnIf you swim in open water, built-in GPS is essential for tracking distance and route. The moutarlier watch features built-in GPS with fast signal lock, so you can leave your phone behind. The EURANS and Enfit rely on connected GPS via your phone, which is fine for pool swimming but less accurate for open water. For triathletes, GPS accuracy is critical; check out our best GPS watches for triathlon guide.
nnnnHeart Rate and Health Tracking
nnnnMonitoring your heart rate during and after swimming helps gauge effort and recovery. All three watches offer 24/7 heart rate monitoring. The EURANS also tracks blood oxygen and stress, while the moutarlier includes abnormal heart rate alerts. Sleep tracking is another bonus for overall wellness. For triathletes who need comprehensive data, our best triathlon training watches guide covers top options.
nnnnBattery Life for Extended Use
nnnnSwim sessions can be long, and you do not want your watch dying mid-workout. The EURANS offers up to 7 days of normal use, the Enfit also lasts about 7 days, and the moutarlier claims 7 days heavy use or 20 days light use. For frequent swimmers, a watch that can last through a week of training without frequent charging is ideal. If battery life is a top priority, see our best triathlon watches guide for more comparisons.
nnnnFinal Thoughts
nnnnAfter reviewing these three swim tracker watches, we believe the best choice depends on your swimming style and budget. For swimmers who want a reliable, budget-friendly option with solid health tracking and IP68 waterproofing, the 1.83″ HD IP68 Waterproof Smart Watch from EURANS is an excellent pick.
