BENU Power Reserve Black/Yellow


For the kick-off with Dynamo Dresden, Moritz Grossmann presents the “Black/Yellow”, a special model of the BENU Power reserve.

The Moritz Grossmann manufacture has a presence as a player at many international events but also places emphasis on its traditional roots with commitments to numerous regional activities. In 2017, the company announced its collaboration with SG Dynamo Dresden. Grossmann CEO Christine Hutter: “In the past years, Dynamo has scored impressive gains with a track record that has elevated the eleven into the 2nd league. Our encounter with sporting director Ralf Minge and chief trainer Uwe Neuhaus was a delightful introduction to a magnificent team, and we look forward to an inspiring spirit of collaboration.”

Moritz Grossmann is now presenting the BENU Power reserve in an edition limited to 11 watches. The special “Black/Yellow” BENU Power reserve model in white gold for Dynamo Dresden stands out with the inimitable aesthetic appeal of the watch family. With its two-colour power-reserve indicator, this watch is the perfect choice for a version in Dynamo Dresden’s livery. When the watch is fully wound, the bar in the dial aperture shows black and gradually turns yellow as time elapses. The black dial is adorned with a stylised ‘D’.

The stainless steel rhomboid hands, manufacture-crafted especially for the BENU, are filled with yellow HyCeram and contrast brilliantly against the dark dial. Additionally, the black alligator leather strap is accentuated with yellow contrast stitching. The limited-edition serial number appears on the caseback. The noble High-Artistic finish of the calibre 100.2 movement can be admired through the display back.

As of immediately, the “Black/Yellow” BENU Power reserve can be ordered directly from Moritz Grossmann; subject to availability, buyers can specify the edition number – from 1/11 to 11/11 – that they prefer.
