I remember asking the salesperson if there were plans to incorporate, at the very least, the heart rate function into a watch on your wrist and possibly even GPS functionality.

The salesperson was quite confident that a watch would NEVER have the capabilities to monitor heart rate and a GPS was way too large to be incorporated into a watch.

I learnt a long time ago that using the word never in terms of technology is dangerous - and so it would be the case in this scenario.

The latest feature that caught my attention was the ability for a watch to measure blood pressure. Most people would be familiar with the process of measuring blood pressure. A sphygmomanometer is used with a cuff and stethoscope to measure the systolic and diastolic pressure.

Which is now replaced with just a watch (and a cuff that is needed for calibration once every 4 weeks).

I have been watching (sorry - couldn't help it) the development of wrist technology with interest and, even involved in technology, I find it incredible what the humble wristwatch is capable of.

My Mum was absolutely gobsmacked the day I showed myself and my daughter making calls between our two watches. As kids we used to joke about having a watch like Dick Tracy but here we were actually using this technology that was first dreamt of in cartoons.

The combination of cellular capabilities and GPS and motion sensors delivers fall detection.

Some modern watches will detect a fall and, if the watch detects no further motion for a minute, the watch will automatically call emergency services.

There is a focus on health with many of the watches so there is no surprise that watches will detect heart rate; blood oxygen levels, sleep patterns and some can even allow you to take an ECG.

The list of features continues with GPS mapping and notifications from social media and other apps popping up on your watch in addition to other alerts that may be anywhere from an irregular heart rate to notice that someone is at your front door.

Listening to music with Bluetooth headphones has never been easier and I still see retail assistants give me a smile of childhood awe when I use my watch to pay for items. With all of these features, most smartwatches are capable of being underwater to a depth of 50 metres - which finally allows the metaphor to be tested when someone is said to be able to talk underwater with a mouth full of marbles.
