After a first unveiling at CES last month, Sony's new look stainless steel edition of SmartWatch 3 launches across the globe from this week. Sony designed SmartWatch 3 stainless steel with a sleek look. It’s the latest edition of Sony's wearable, specifically designed for Android Wear’s standalone functionality - meaning you can load tunes & playlists to the on-board memory, leave your Android smartphone at home and go for a run…and track that workout with the in-built GPS sensor and Lifelog.

Next up, Sony's modular SmartWatch 3 "holder" kit will launch over the coming weeks – it will allow you to customise SmartWatch 3 with any 24mm watch strap, but will also be available with either brown or black leather strap options to get you started. If you’re a current SmartWatch 3 user, it’s worth noting Sony will also make both the leather and stainless steel straps available for separate purchase from early spring.

After making premium versions of Golfshot and iFit available for the sporty SmartWatch 3 users out there, Sony says all new SmartWatch 3 stainless steel and "holder" kits will include vouchers for six months exclusive access to the Todoist Premium right out of the box. In case you haven’t heard, Todoist is a personal task manager and to-do list app that will help you achieve more each day by becoming more productive.

Headset for smarter jogs

Sony will also soon begin selling headphones that record data and offer tracking functions to runners.

Annouced at CES, the Smart B-Trainer is an all-in-one, lightweight, headset-style device made for runners and equipped with essential running sensors and music playback capabilities. It logs a variety of data on the move, including heart rate and route traveled. If the heart rate misses the target, a built-in feature can change the music to faster songs as an encouragement to pick up the pace. After a training session, data on the Smart B-Trainer is transmitted to the user's smartphone via Bluetooth.

The device features six sensors, including an accelerometer, a barometer and a GPS system. It can measure and record 11 types of running data, such as calories burned, distance and pace. It has a 16GB built-in memory and will debut March 7 and sell for around 27,000 yen ($220) in Japanese stores.
