Moritz Grossmann 37 ARABIC Black&White

Premièred in London on 11 July 2019 at the international Moritz Grossmann Roadshow 2019, the 37 ARABIC Black&White watch features a high-contrast design in black and white gold featuring lively Arabic numerals in white.

With the 37 ARABIC Black&White, the independent Glashütte manufacturer Moritz Grossmann interprets the iconic colour contrast with an outstanding feel for aesthetics and elegance.

The deep black dial allows the lines of the white elements to stand out brilliantly. Brilliant 750/000 white gold effectively sets off the case and the winding crown and gives the watch an exquisite frame. A strap made of black alligator leather with a white gold clasp underlines the elegant design character. The housing is slim with a diameter of 37 mm. As a smaller version of the successful BENU line, the 37 ARABIC Black&White captures its characteristic rhombic design language.

The sweeping white numerals in Arabic script are a real eye catcher and almost seem to dance around the pair of hands. This forms a calm fixed point in its straightness. The hand crafted Grossmann hands made of polished stainless steel can be read precisely.

Two further details emphasise the play of opposites with their white colouring: a Moritz Grossmann logo completely in white and a harmonious white “Made in Germany” seal of approval. Both were varied for the 37 ARABIC Black&White.

The watch appears in the manufactory calibre 102.1. With a diameter of only 26mm and a height of just under 4 mm, the mechanism follows the classic basic construction with a 3/5 plate. It works with an uneven escapement specially developed for this mechanism size as well as a modified regulation. The casing made of sapphire crystal provides a fascinating insight into the movement play of Grossmann’s building elements, which shine in an artistic finish.
