Switzerland(瑞士) is famous for its watches。 However, this country didn’t invent the watch。It was the British who did it。 Here is a story of how the watch was brought to Switzerland。

Many years ago , an Englishman was travelling to Italy 。 On his way he stopped in a small town in South Switzerland。 This Englishman travelled in a carriage(马车) inside which there was a carriage watch。 This was the earliest kind of watch。 A native shop assistant (售货员) happened to see the watch 。 He wondered what it was and asked the Englishman about it。 “ It is a carriage watch 。” said the man 。 This machine tells the time but now it isn’t working 。

At once the shop assistant offered to try to repair it 。 So the traveller handed him the watch。 The assistant was a very wise man 。 So it was not surprising that he managed to repair it 。 He even remembered how it was made。 As soon as the traveller had gone on his way , he made a watch exactly the same type。

Thus the watch-making was started in Switzerland。 Today Swiss watches are sold in stores all over the world。
