The RÉSERVE DE MARCHE CLASSIQUE is reminiscent of a historical pocket watch by the Glashütte watch pioneer Moritz Grossmann. The slender casing in 750/000 white gold and a coordinating rhodié dial give the watch a bold aesthetic. In addition, the black Roman numerals and the Moritz Grossmann logo in typography dating from 1875 provide an effective historical counterpoint. The power reserve is designed as a two-colour bar-shaped indicator element. The display bar is slightly narrower and placed directly under the historical logo lettering. When the movement is fully wound, a completely white bar is displayed and when the power reserve decreases, an increasingly blue bar is displayed.

The sapphire crystal back on the rear of the watch reveals the fascinating interplay of the fine mechanical elements. As a sign of appreciation, Moritz Grossmann founder and CEO Christine Hutter has personally signed the RÉSERVE DE MARCHE CLASSIQUE. Her signature is embedded in the glass bottom in the form of a gold thread.

"Participating in Only Watch is a matter close to our hearts at Moritz Grossmann" emphasises Christine Hutter. "This is exactly what I wanted to express with my signature on the collector’s item. Our manufactory would like to contribute to helping children suffering from Duchenne. We have created a piece of "Schönstes deutsches Handwerk’"with a great deal of passion and hope to inspire all watch lovers with this piece".
