Moritz Grossmann BENU No. 1 (Unique piece in 750/000 rose gold)

Posted on by

This unique timepiece was the very first watch manufactured on the early premises of the manufactory on Hauptstraße in Glashütte following the revival of the name Moritz Grossmann.

The watch, limited to a run of 100, was sold out after a short time except for this one. The solid silver dial in the shade argenté is adorned with Arabic numerals and handmade brown-violet hands tempered over an open flame.

The BENU No. 1 in rose gold radiates individuality and unobtrusive elegance in its classic design; qualities that also characterise the uncrowned old master and the man who gave the company its name, Moritz Grossmann.

The BENU No. 1 is offered with the calibre 100.0 in the high artistic hand finish with the engraving 001/ 100.
