Buben & Zorweg’s Pythagoras World Time Tourbillon

May 2006

At BaselWorld 2006, Buben & Zorweg presented its new World Time collection of mechanical clocks, including the first ever world time mechanical clock with a tourbillon.

This 15-day mantle clock was named after the famous Greek mathematician, Pythagoras, because of its striking triangular shape. It has a flying minute tourbillon incorporating the B & Z initials and an intricately crafted silver-plated dial. There are indicators for world time, seconds, date and a power reserve.


The movement is made by the German manufacturer Erwin Sattler and is cased in macassar wood, metal and crystal.
