In 1931 Rolex patented a self-winding watch movement, this was one of the first movements to be wound through the means of a rotor ‘weight’. This weight moved as the wearer moved their arm and wrist, constantly winding the mechanism. Hence the moniker ‘Perpetual’ as it would be perpetually wound. Midsize made from 1960 till 1986 and then 1987 till 2014. In 2014 saw the advent of the new Oyster Perpetual in 4 different sizes, 26mm, 31mm, 34mm and 36mm.
If you this example of 2010 you get those spring vibes. Soft colored markers on a silver dial, surrounded by 18k white gold bezel. It comes with original box and papers, so full set. The 31mm is a comfortable size for every lady, not too big not to small, very hot at the moment. We find it a ‘sweet’ watch, for a lovely lady!
