For sale today is a rare, good condition trench watch circa 1910s - 20s.
This trench watch is from at least 1913 - ~1920s. This watch is of the "Hebdomas 8 Day" patent which as the name suggests is a very early 8 day or 192 hours power reserve movement. To speak briefly of the history of the trench watch; the first purpose-made men's wristwatches were produced by the Swiss brand Girard-Perregaux for the German Navy in 1880. These were quickly followed by many other wristwatches from other familiar brands like Omega. The "Hebdomas 8 day" patent however has an entirely seperate history.
The 8-day movement was invented in the 188 in the Vallée de Joux in Switzerland. The patent was granted later on January 10, 1889. This watch featured predominantly in iconic pocket watch and wrist watches where the larger mainspring caused the balance assembly to move on the watch down to 6 o'clock and then was exposed as an early "open heart" design. However, the movement was also admired for its functionality in a trench watch and was added to many like our example here. Having an 8 day power reserve would have been useful for an officer of the Great War.
This watch has been overhauled by our watchmakers just before sale and comes with our 12 month warranty.
This is a real piece of history for an affordable price and one day these pieces will be even more rare than they are now.
