Watches are very rarely just an excuse to put something cool on your wrist.
As is the case with the five watches shortlisted for our Technical Innovation of the Year award, they are marvels of innovation - and usually the result of years of research and development.
The world of horology has been obsessed with coming up with solutions to everyday problems since the very beginning of the wristwatch.
What we see in these contenders goes beyond that.
These are the watches of tomorrow ready to wear today.
