Sechseläuten is a fire and spring festival in Zurich at which the Swiss ceremonially drive out winter every year. This year, the traditional spring festival of the guilds will be celebrated in the form of a big folk festival on 8 April. As a highlight, the Böögg, an oversized snowman filled with wood shavings and firecrackers that symbolises winter, will be set on fire on a large pyre in the middle of Sechseläutenplatz at 6 p.m. on the dot.

Grossmann Uhren will celebrate the start of spring and its proximity to Switzerland by launching a very special watch to mark Sechseläuten. The Moritz Grossmann SECHSELÄUTEN is offered as a one-off piece in cooperation with the Swiss fashion label GROSSCOUTURE and will be presented from 2-13 April in their exclusive pop-up store on Zürich’s Paradeplatz.

The Moritz Grossmann SECHSELÄUTEN is presented in the classic design of the BENU line. At 12 o’clock there is a ‘6’ in the typical Swiss red on the dial. The colour of Switzerland also glimmers on the scale of the small second. Instead of the 60, a 6 is applied in the same shade of red. The Arabic numerals and the minute scale are in blue. The dial is in white enamel Grand feu.

Instead of the writing ‘Made in Germany’, which traditionally decorates the lower part of the dial of the Moritz Grossmann watches, on this model the writing SÄCHSI LÜTE between the small second and the minute highlights the connection to Sechseläuten and Switzerland.
