Glashütte Original celebrates anniversary of a watch classic

The Perpetual Calendar combines the pinnacle of horological expertise and maximum functionality in a truly unique way. 20 years ago, Glashütte Original gave the complication a face that is a firm feature in the Senator collection to this day. It was in 1999 that the Senator Classic Perpetual Calendar first presented the different calendar elements as elegant puristic windows instead of the previously customary circular displays. This harmonious arrangement has featured in every Perpetual Calendar model of the Senator series since.
