2007 Sony Ericsson MBW-150
Still, the demise of Spot did little to dampen the tech industry's enthusiasm for smartwatches. But, as mobile phones become more sophisticated, the idea of pairing a watch with a phone became something for tech companies to explore.
Here's the Sony Ericsson MBW-150 – the watch could be paired with a Sony Ericcson phone via Bluetooth and had a small single line OLED display. When an incoming call is received, the watch would vibrate and show either the name of the caller or their number. The watch could also notify the wearer about new text messages, and came in three models: classic, music (above) and executive.
