This "100 Jahre Zeppelin" model combines classic elements such as a domed dial and crystal with the modern look of a chronograph. Inside the polished stainless-steel case with a diameter of 42mm ticks a precise quartz movement from Swiss manufacturer Ronda, which in addition to a chronograph function also has an alarm. The rounded crystal is made of specially hardened K1 safety glass. Luminous elements on the dial and hands ensure good readability even in the dark.This "100 Jahre Zeppelin" model combines classic elements such as a domed dial and crystal with the modern look of a chronograph.
