Glashütte Original - Preview Baselworld 2014: PanoMaticInverse

Glashütte Original - PanoMaticInverse.

Introduced to great success in 2008, the PanoInverse XL was the first of the Saxon watchmaker’s timepieces to reveal its inner beauty, presenting this very special form of fine adjustment on the face of the watch. This was made possible by the inverse positioning of the components that are normally visible through the case back’s sapphire crystal. To achieve this it was necessary to refine many of the movement components and to further develop individual components and sub-groups, which led to a completely new design of the manual winding Calibre 66.

The PanoMaticInverse, which celebrates its debut at Baselworld 2014, takes this idea further and is presented here with the new Calibre 91-02, a precise automatic movement with a ...

Stichwort: Hampden-Dueber Watch Co.

1929 wurde die gesamte Hampden-Dueber Watch Co. in Canton (Ohio) an Armand Hammer, einen Beauftragten der Firma Amtorg, für ca. 325.000 US$ verkauft. Bei der 1924 gegründeten Amtorg Trading Corp. mit Sitz am Broadway in New York handelte es sich um eine Außenhandelsvertretung des Obersten Wirtschaftsrates der UdSSR, die unter dem Motto "Amerika einholen und überholen" Know-How-Transfers vom Westen in den Osten abwickeln sollte und dafür die benötigte Finanzierung bereitstellte.

Die Amtorg ließ 1930 alle Maschinen und Teile in die damalige Sowjetunion verschiffen. 21 amerikanische Angestellte der Firma siedelten in die Sowjetunion um und unterrichteten die russischen Arbeiter in der Uhrmacherkunst. Im selben Jahr 1930 wurde von den Russen das neugewonnene Know-How in die Gründung der 1. Moskauer Uhrenfabrik (Poljot) eingebracht.

Uhrwerk mit Quarzoszillator als Zeitnormal

Quarzuhr

Bei einer Quarzuhr dient ein Quarzoszillator als Zeitnormal. Das Signal des Quarzoszillators wird über einen Teiler, der quasi dem Räderwerk des Gehwerkes entspricht, von 32.768 Hz auf 1 Hz heruntergeteilt.

Wesentliches Bauelement des Quarzoszillators ist ein Schwingquarz, der eine sehr viel höhere Ganggenauigkeit bringt als ein mechanisches System. Er besteht aus einem SiO2-Plättchen, das an zwei Seiten metallisiert ist. Durch Anlegen einer elektrischen Spannung verformt sich der Quarz. Durch die Rückkopplung kommt es ...
