One for the mystery dial collectors and tonneau watch lovers. For sale we have an excellent piece of design from the 1940s by Election, one of their mystery dial watches, seemingly following the same design as the Marvin Gyroplan.

 The slate grey dial is original, with central hour disc and outer minute disc. The white painted signing is clear and balanced, creating a stylish display. The tonneau case is formed of Steel and has a facetted design which catches the light. Inside is a manual wind Election calibre 306 movement which is recently serviced.


The mystery dial is known as such due to the un-conventional display of the hours and minutes. On this example, the minutes are indicated by a central disc which has a pointer towards the minutes. The outer disc has a different colour pointer which indicates the hours. The discs spin to demonstrate the time which is a novel and appealing technique.


The first mystery dial configuration was designed by 19th century Frenchman Jean-Eugene Robert-Houdin who was known as the father of modern magic. Prior to his magic exploits, he followed his father’s footsteps as a watchmaker.


He designed a clock which he incorporated into his act, with the hands appearing to merely float, with the transparent dial. This was achieved using clear discs with concealed toothed edges, with the mechanism also hidden. Cartier also created the Model A Mystery clock in 1912.


Marvin manufactured the earliest mystery dial wristwatch with the Gyroplan in the late 1930s. Examples were also manufactured by Election in the same design, such as this.


It wasn’t until the 1940s that other makers applied the concept to wristwatches, first by Juvenia, known as the Mystere. It was also used by makers such as Longines, Le-Coultre, Vacheron Constantin, Election and Zodiac.


Examples by Election are quite uncommon and are some of the more stylish examples available. They tend to make use of rectangular and tonneau shaped cases, with this example having a Stainless-Steel case with facetted design. The dial is good and original, of a tonneau shape with pointed sides matching the top of the case. It measures 22mm x 29mm, with a lug-to-lug measurement of 36mm.
