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.
2009 Samsung S9110
This is one of the slightly more unusual smart devices - a watch that was also a phone. This Samsung S9110 from 2009 was at the time touted as the world's thinnest watchphone, sporting a 1.76-inch touchscreen, Bluetooth, email support and MP3 playback. Samsung is another company that has made a number of attempts to crack the smartwatch market - more of which later in this gallery.
The 12mm thick device also supported voice recognition and speakerphone and had a 40MB internal memory.
