About any watch it can’t be
claimed that that it will give exact time at every place. Even the watches which
are matched with Atomic clocks are not accurate. In such watches a built-in radio
catches signals from long range towers which are connected with atomic houses
of different regions of world, however their range is only limited to 1500
miles because of which they can’t cover big regions like north America, Canada,
etc. But now Japans watch Maker Company SEIKO made ASTRON wristwatch in which
first time Global Positioning System (GPS) is used. And only because of GPS it
can automatically set its time anywhere in world.
