(IDEX Online) - A major watch retailer has ditched the terms "men's" or "women's" and now describes watches as small, medium or large.Watchfinder & Co, Britain's largest seller of second-hand watches, says gender terms are "redundant, restrictive and outdated".It says it is reflecting a trend set by Kayne West, Jay-Z, Victoria Beckham and other celebrities to wear watches designed for the opposite sex.Matt Bowling co-founder of Watchfinder & Co, said: "By removing the men's and women's categories from our business, we are encouraging customers to explore and discover more watches, helping them find the right watch for them."With a large proportion of men's watches getting smaller and women's watches getting bigger, we feel that gender categories are now obsolete."
