The TomTom Spark is a line of six running watches, all of which include GPS, all-day activity tracking (steps, distance, calories burned, active minutes), automatic sleep tracking, Bluetooth to connect with smartphones, interval training and a water-resistant rating of 5 ATM.
The entry-level TomTom Spark only includes the features listed above. The TomTom Spark Cardio adds a built-in optical heart rate sensor. The TomTom Spark Music doesn't include a heart rate sensor, but does include 3GB of storage for songs. If you want both heart rate tracking and music storage, there's the TomTom Spark Cardio + Music.
TomTom is also offering two additional models of the TomTom Spark Music and the TomTom Spark Cardio + Music that will come bundled with a pair of TomTom-branded Bluetooth headphones.
The TomTom Spark Cardio + Music is available now for preorder in the UK for £190. Preorders will start on October 1 in the US for $249. The full range of Spark watches will be available for purchase on October 15.
