Germany will be celebrating the 30th anniversary of German reunification on 3 October 2020, an event we would like to acknowledge with the U1 DE special edition. The reunification has another significance beyond this historical date for us as a German watchmaker. For us it’s synonymous with the story of two companies which continue to actively embrace the merging of east and west to this day: qualified engineer Lothar Schmidt, owner of Sinn Spezialuhren, and Doctor of Engineering Ronald Boldt, co-owner and Managing Director of Sächsische Uhrentechnologie GmbH Glashütte (SUG), have continued to develop the partnership established in 1999 between Sinn Spezialuhren and SUG. Lothar Schmidt has held 74% of all SUG shares since the disastrous flood of 2002. Working with Ronald Boldt, he has created an upmarket case manufacturing company, which is now successfully managed primarily by son Daniel Boldt.
To mark this special occasion, we’ve designed the watch in Germany’s national colours. The colours black, red and gold, which have always been a symbol of German reunification and are anchored in the constitution as the colours of the flag, go all the way back to the Wars of Liberation (Germany, 1813 – 1815). The black, red and gold flag appeared in its present-day form at the Hambach Festival of 1832 for the first time. Reunification was celebrated with the raising of a black, red and gold flag in front of the Reichstag building in Berlin.
