Clocks have been invented since "God knows when", and like everything else, they are constantly evolving into complex mechanisms that blow our minds away. They tell time in the most amazing way especially when it comes to clocks inside wristwatches. Every piece of this tiny machinery is very well calculated and put together with utmost precision so that not a single piece can go wrong. The price for these timepieces are very high, but every cent is well represented from their precision engineering to beauty and high quality. Actually, you're not losing money, you're owning a treasure.
