After the successful launch of their exclusive collection of mechanical wristwatches in 2009, the watch manufacturer Hanhart begins 2010 with three new Primus models. The new collection immediately became a sign of the times. An exclusive, sporty chronograph line, consisting of a few select pieces, elegantly designed, combining the historical element with the latest technology – and with the unmistakably unique signature that has distinguished Hanhart since 1938: the red button that safeguarded pilots from accidentally resetting the deceleration time.
