Occasionally you will stumble across the term „bicompax“, when it comes to dial design and the arrangement of totalizers. But what is actually the meaning of this term and where does it originally come from?
In 1936, the Swiss watch manufacturer Universal Genève SA launched the chronograph “Compax”, which displayed the measured minutes and hours on two sub dials. The “Tri-Compax” chronograph has been presented in 1944/45 and featured also a calendar with date, lunar phase, day and month besides the usual chronograph functions.
“Bicompax” is a more modern definition for chronographs with a pair of sub dials. This specification has strictly speaking technically no meaning, rather it has gradually established itself in the world of watches. Therefore this term has proven confusing for some watch enthusiasts and has led to a widespread use. Nonetheless, thanks to this terminology, there is no other word, which describes this special dial design with two totalizers better.
One of the most distinctive Hanhart trademarks is exactly this “bicompax” display format, coming from the legendary Hanhart manufacture Cal. 40, 41 and 42. The totalizers of small second and 30-minute counter are arranged horizontally at 9 o’clock and 3 o’clock. It can be found on every Hanhart chronograph.
