Sony has launched a different take on the smartwatch, with all the technology embedded in a band that users can attach to their favourite analogue face.
The Wena watch strap upgrades any traditional watch with fitness tracking, contactless payments and phone notifications.
All of the technology has been carefully designed to fit within the gentle curve of the watch clasp, including a small OLED screen where notifications are displayed.

Two strap designs are available: the Wena Wrist Pro, a classic metal link style in either silver or black, or the Wena Wrist Active, which has a silicone strap made for fitness.
The Active model comes with additional GPS and heart tracking. It also has a "quick-release system" that allows the watch face to be easily removed during exercise, making the accessory lighter and giving it the appearance of a Fitbit-style fitness tracker. Both band styles are 20 millimetres wide and attach to any watch that takes an 18-, 20- or 22-millimetre lug, although Sony also offers the option of five of its own watch face designs.
