Big companies have been trying hard to make the long-awaited smartwatch "revolution" happen, so tick tock, what's taking so long?
Smartwatches are just not very smart when left to their own devices - they need to be connected to a smartphone for full functionality.
While the industry is growing quickly, nearly all still need a smartphone's Bluetooth connection to tell you much more than just telling the time.
Apple's smartwatch is rumoured to exist already... or not exist at all. Or exist sometime soon
What a smartwatch could potentially do, at least to thousands of children in the 80s, was typified by the wristwatch David Hasselhoff's character used in Knight Rider to control his car.
But the industry is still so new there are many different approaches.
"Smartwatches can already be split into three or four categories," says senior analyst Josh Flood, of ABI Research.
"There are notification watches - the really basic ones which just link to the phone, voice-capable smart watches which is a really cool idea and health and fitness smartwatches for heart rate and running."
Others see even greater potential.
"Through NFC [near field communication], could you transfer travel cards to the watch?" says Skooks Pong, vice president of Synapse, a company working with Nike to develop its FuelBand activity tracker/watch hybrid.
