Will it change the face of wearable technology?

The hotly anticipated Apple Watch went on sale
24 April 2015 and there are 38 different versions
available. These include two different face sizes,
38 millimetres (1.5 inches) and 42 millimetres (1.7
inches), to suit smaller and larger wrists, and
multiple strap and metal variations. Prices
range from £299 ($349) for the basic Sport model
to £13,500 ($17,000) for the top-of-the-range
18-karat gold Apple Watch Edition. In fact, Apple
has invented a new kind of gold for its luxury
timepiece. Rather than combining three parts
gold with one part silver or copper, which are
standard metals used in alloys, Apple has used
ceramic instead, a low-density material that
makes the gold twice as hard and more resistant
to scratches.
You can expect to get about 18 hours of typical
everyday use out of your Watch between
charges, but the battery life can be extended to
about 72 hours if you activate the Power Reserve
feature that turns most of the functions off. It
will then take approximately 2.5 hours to go
from zero to full charge when you clip on the
wireless charger.
As well as being able to accurately tell the
time to within 50 milliseconds via the
customisable face, the Watch can also run a
variety of other functions when paired with an
iPhone 5, 5C, 5S, 6 or 6 Plus. It can be used to
make and take phone calls via the built-in
speaker and microphone, receive and send text
messages by dictating them, selecting from
preset templates or simply selecting an emoji,
and it can track your fi tness using a variety of
built-in sensors. However, it can only measure
the distance you travel when you have your
GPS-enabled phone with you too.
Thousands of apps have also been developed
for the Watch, enabling you to access social
networks such as Facebook and Instagram,
summon a taxi via Uber and identify the name
of a song using Shazam. It will also come in very
useful when travelling, as you’ll be able to use it
as your boarding pass at the airport and as your
room key when you get to the hotel.
