The Rolex Oyster
Following the end of World War I, global trading resumed and Rolex watches were being sent abroad, particularly to the the hot and humid tropical countries of the British Empire. Many of the watches were found to have rusted on arrival following a long damp voyage!
Hans Wilsdorf (co-founder of Rolex) was determined to produce a ‘water-proof’ watch and commented;
“We must succeed in making a watch case so tight that our movements will be permanently guaranteed against damage caused by dust, perspiration, heat and cold. Only then will the perfect accuracy of the Rolex watch be secured.”
The Rolex Oyster watch was produced a few years later in 1926 with a ‘three-piece’ case, (the front and back screwing into the body). An iconic design that has become probably the best selling waterproof wristwatch.
The ‘Oyster’ name was registered in 1926, an inspiration of Wilsdorf when he struggled to open an oyster at dinner.
