On the 50th anniversary

The key for the future in-house developed movement lies again in the past: Fascinated by the Maltese cross mechanisms in the old precision pocket watches and by a drawing in an old manual for watchmakers by Hermann Sievert (1914), Dirk was favouring this position of the springs also for the new movement. Together with his team, he developed a unique Maltese cross construction, visible through sapphire glass, which realizes an almost linear torque to power the balance by means of two barrels connected in series, thus permitting a higher rate accuracy. Further the Maltese cross construction serves as an interlock device which can clearly be noticed when the watch is fully wound.

Apart from the big screw balance with a Breguet spring beating with classic 18,000 semi-oscillations, the D. Dornblüth & Son team integrated another classic but forgotten element of the 1940s: the short anchor escapement with a lowered escape wheel. This special construction considerably reduces the positional errors caused by the anchor escapement.
