François Borgel
Towards the end of the 19th century in Geneva, Switzerland, François Borgel set up a business making watch cases. In 1891, he patented the screw watch case design that most often bears his name today, the Borgel case. This case was used for Borgel pocket watches before achieving wide use for Borgel wristwatches during the First World War, often purchased by officers to wear in the cramped conditions of the trenches instead of the standard issue pocket watches of the day, hence the terms Borgel officer’s watch or Borgel trench watch.
