Notes

Uhrenfabrik Union Glashutte's Johannes Durrstein series of limited edition wristwatches. Using classic gold "cushion" cases, the series includes: a simple hand-wind (No. 1); a perpetual calendar (No. 2); and a flying tourbillon (No. 3) all limited to 50 pieces each.
Flying Tourbillon. As opposed to regular tourbillon regulators in which the carriage is fitted in a plate and secured by a bridge, in flying tourbillons, the lower bearing of the carriage is fitted in the plate in the regular way, the upper bearing is fitted beneath the carriage, and the carriage is built around a free (flying) arbor. On the top of the carriage, there are neither pivot nor bridge.
Union In 1883, the Dresden watch wholesaler, Johannes Durrstein realised that in times of financial hardship only a very small number of his clients could afford the fine and expensive original Glashütte watches. This led to his establishing the Präzisions- Taschenuhrenfabrik UNION Glashütte in Sachsen, where he made fine precision watches and everyday watches of modest price. Even today, this traditional company makes watches that represent the highest level of German watchmaking and that are entirely conceived and made in Glashütte.
