Josef Pallweber of Salzburg took out a Patent in England on 1883 for his mechanism to display the time in digital format.  It was adopted by International Watch Company in 1884 and produced by them for about five years.  In 2018, to celebrate their 150th anniversary, IWC produced a wristwatch with a similar mechanical digital display as a tribute to Pallweber.  Made in limited numbers these wristwatches are priced from $30,000.
