This competition is now closed. Congratulations to the winners, who are Adam Rowledge from Rugby, UK, Katie Zwarts from London, UK and Graham Williams from Wrexham, UK.
To celebrate the launch of the smartwatch, three lucky readers could win a combination of both a band and watch face of their choice from the Wena range, which stands for "wear electronics naturally".
All of the technology is embedded within the smooth curve of the watch band, including a small OLED screen where notifications are displayed.
This means that users can upgrade any traditional watch with various smart features such as fitness tracking, contactless payments and phone notifications.
Readers can win a choice of three different Wena watch versions, including the stainless-steel Wena Wrist Pro, which boasts a classic metal link design and comes in either silver or black.
The third option is the Wena Wrist Active, which has a silicone strap made for fitness. This version also features an additional built in GPS and heart rate monitor.
Both strap styles are 20 millimetres wide and attach to any watch face that takes an 18-, 20- or 22-millimetre lug. However Sony also offers the option of five of its own watch face designs.
You can choose a premium Mechanical watch face, which features a transparent back through which you can see the Miyota 905S movement. There are also two solar-powered models and two entry-level quartz models, each available in Three Hands and Chronograph styles.
The straps connect to a phone via Bluetooth, and users can customise the look of their notifications with a range of seven coloured-LED lights and vibrations.
The watches are also available to buy on the Sony website or in store.
Competition closes 10 July 2019. Three winners will be selected at random and notified by email, and their names will be published at the top of this page. Entries from UK and Ireland only.
