TomTom has unveiled two new GPS sport watches.
The Dutch company has announced the TomTom Runner, specifically for joggers, and the TomTom Multi-Sport, specifically for swimmers and cyclists.
Both new sport watches use a large display, have a single button for operation and will comfortably fit all wrist sizes for men and women, the company says.
TomTom's consumer managing director, Corinne Vigreux, said the new watches address the failings of most GPS watches currently on the market.
"We know that most GPS watches on the market are too bulky and complicated to use while training. We have developed a range of ultra-slim GPS sport watches that are far more comfortable to wear and far easier to use."
Both the TomTom Runner and Multi-Sport watches have three "graphical training modes" including race times, distance, time or calorie goals, and a zone mode that allows a pace or heart-rate target to be set, the latter with an optional heart-rate monitor.
TomTom says the one button control on both watches can be easily controlled in all weather conditions and while wearing gloves.
An indoor tracker feature can track indoor runs on a treadmill and both watches can sync and share statistics and data through popular running sites and platforms such as RunKeeper and MapMyFitness.
Both the TomTom Runner and Multi-Sport watches feature a scratch resistant display, are waterproof up to a depth of 50 metres and have a battery life of "up to 10 hours".
The TomTom Multi-Sport adds a dedicated bike mount, a cadence sensor, a built-in altimeter, and a swimming motion sensor.
Both the TomTom Runner and TomTom Multi-Sport watches will be available in mid-2013 but TomTom is yet to announce Australian pricing or release details.
