Moritz Grossmann BENU Gangreserve SGD 1953 – Unique Piece Signed by Ralf Minge, the Legendary SG Dynamo Dresden Striker

The independent Glashütte watchmaker Moritz Grossmann  is celebrating its 10th anniversary this month. To mark this occasion, the company presents its eleventh special model, The BENU Gangreserve SGD 1953. The special piece has been hand-signed by legendary Dynamo Dresden striker, Ralf Minge, to celebrate the regional roots of the manufactory. The name ‘SGD 1953’ is often used by fans and is short for SG Dynamo Dresden football club and its founding year.

Dynamo Dresden’s iconic striker of the 80s and today’s sporting director has signed the unique new edition ‘SGD 1953’, a version of the BENU Power Reserve ‘Black Yellow’. Minge’s signature is applied in the form of a gold thread in the glass back of the watch.

The special model BENU Gangreserve SGD 1953 is presented in white gold. The two-coloured power reserve indicator of this unique model is painted to SG Dynamo Dresden’s signature black and yellow.

The watch is fully wound if the black part of the bar appears on the dial. As the spring runs out of tension, the bar becomes more and more ‘Dynamo’ yellow. The characteristic ‘D’ of the SG Dynamo Dresden logo decorates the centre of the black dial in discreet dark grey. The BENU Gangreserve SGD 1953 is offered with the calibre 100.2 in artistic hand finish as a single edition 1 of 1.
