Caliber 99.3

It was already when finalizing the development of the Caliber 99.2 that Dirk dreamt of integrating an additional complication – the date. Both masters knew that this would require some more time to develop. The Caliber 99.3 unites the large eccentric second of the Caliber 99.1, the 99.2 power reserve and the new idea of the date display.
