Pelagic One tracks every length, stroke and turn from a sapphire-glass watch that weighs 31 grams and survives 100 metres down.
Lap count, pace and heart rate update on your wrist and in the app the moment you touch the wall.
Pelagic reads force through every pull. Pick a stroke to compare your rhythm with the ideal.
Pick a mode, press the side buttons or swipe the screen. Every number is live, just as it runs on the watch.
Up to 14 days with a daily one-hour swim. Twenty minutes on the magnetic dock covers your next three sessions.
Rated to 100 metres with a sapphire-glass front and a sealed, buttonless crown, so chlorine and salt water are no problem.
An optical heart-rate sensor, gyroscope and accelerometer count laps and strokes without a single button press.
Works in 25 m and 50 m pools and recognises freestyle, backstroke, breaststroke and butterfly automatically.
Ships in spring. Fully refundable until it leaves our warehouse.
