Before World War I only women wore wristwatches, they were considered 'unmanly'. Wristwatches became fashionable as a result of their use by soldiers in WW1, who needed access to their watches while their hands were full. These first wristwatches, called 'trench watches', were made with pocketwatch movements, so they were large and bulky and had the crown at the 12 o'clock position like pocketwatches. After the war pocketwatches went out of fashion and by 1930 the ratio of wrist- to pocketwatches was 50 to 1. The first successful self-winding system was invented by John Harwood in 1923. http://en.wikipedia.org/wiki/Watch#Wristwatches:_1920 Jun 09 09, 12:11 PM
