Have you ever dreamed of having a fashionable watch of great value?

A small watchmaker in Switzerland in 1922 designed the first automatic watch to show the day,month,and date.Only seven of these splendid watches were ever made and these watches were almost lost to history.Today,it is so hard to get an original watch that some watch historians are even willing to offer $ 200,000 for one.

These watches attracted a lot of people for their splendid color,fashionable style,and new uses in the 1920s.The owners of the watches were admired and set apart from the crowd.Because the number of the original watches is very limited,owning such a watch will make you feel very special.

Today,you are offered the same kind of watch with improvement.The watch has a 24-jewel mechanical(机械的)movement,the kind desired by watch collectors.The watchmaker has made the movement of the watch much more modern with an automatic rotor(上弦装置)so that the watch never needs to be wound by hand.The watch comes in a very beautiful case with a crocodile design on it.To get a watch in such a perfect design means to get a chance to know a piece of watch making history and to wear such a watch will show your personal taste and social position.

You can get the watch either in person or by mail at an affordable price.You will also receive good service from the watch seller.If you are not satisfied with the watch after you get it,you may simply return it within 30 days.Don’t miss the chance to realize your dream.
