With the TEFNUT Lady Butterfly, watch manufactory Moritz Grossmann presents a slice of great happiness in the smallest space. In accordance with the artistic design created by Harriet Oberlaender, a swarm of colourful butterflies has been painted on the mere 29 mm mother of pearl dial by hand in the form of a miniature painting.
For the artist, the butterfly is a playful symbol of lightness and the preciousness of each moment.

The new model will be presented on 5 April 2019 to an exclusive audience in the Moritz Grossmann manufactory in Glashütte. In addition to the TEFNUT Lady Butterfly, selected works by the artist Harriet Oberlaender will also be on display as part of a exhibition of paintings.

Born in Zwickau, artist Harriet Oberlaender has lived and worked on the Cote d’Azur for more than 20 years and has inspired an international audience in numerous exhibitions in France and Germany. Her expressive, energetic works are characterised by a feeling of freedom, expanse and the search for true happiness. Her visual language leads straight to the heart. The butterfly – one of the key motifs in her works – is a symbol of the human soul that wants to unfold and fly.

The design of the TEFNUT Lady Butterfly was particularly close to the artist’s heart: ‘I’m really pleased that I’ve been able to realise the TEFNUT Lady Butterfly for Moritz Grossmann. I want every glance at the watch not only to reveal the time to the wearer, but also remind her of the happiness of a fleeting moment’.
