Jaeger LeCoultre Reverso Watch
It all started during the winter of 1930-1931. While travelling in India, the Swiss businessman and watch collector César de Trey attended a polo match at a club of British army officers. One of these officers, who had just broken the glass of his watch, challenged de Trey to create a watch model robust enough to resist to a polo match. César de Trey discussed the idea with Jacques-David LeCoultre, the then owner of the LeCoultre manufacture, who could provide the movements for the new watch.
LeCoultre appointed the firm Jaeger S.A. for the creation of the reversible case, which in turn contracted the French designer René-Alfred Chauvot, the actual inventor of the unique slide and flip mechanism. The result was an elegant watch with a dial that could flip, protecting it from shocks while offering a personalised engraved case-back. Source: timeandwatches.com
