The Basics

In 2015 Glashütte Original took up the spirit of discovery once again with a new version of its Senator Observer, a sophisticated observation watch (also known as a ‘deck watch’) evoking the enthralling history of navigation at sea. The Saxon manufactory’s in-house dial manufactory has made extensive use of luminous surfaces to make the new Senator Observer easy to read in the absence of light: the elegant white gold hour and minute hands, bold Arabic numerals, and chapter ring hour indexes are all highlighted with green Superluminova, a phosphorescent pigment that absorbs light by day and emits it at night. The hand and indexes of the small seconds subdial at 9 o’clock and the power reserve indicator at 3 o’clock are also luminous by night. By day the matt black dial offers an elegant backdrop and contrast to the Arabic numerals, drawn in a font once widely used for precision pocket watches made in Glashütte at the beginning of the 20th century. At the centre of the lower half is the noted watchmaker’s compelling Panorama Date display.

About Glashütte Original

Glashütte Original logo

With the reunification of Germany in 1990 came the transformation of VEB Glashütter Uhrenbetriebe into the Glashütter Uhrenbetrieb GmbH. The company is the official legal heir to all formerly independent watch companies extant in Glashütte up to 1951. Since 1994 the brand name “Glashütte Original” has stood for fine German watchmaking with a high degree of production depth. In 2000 … Glashütte Original was honoured for the first time with the much sought-after title of “Watch of the Year”: Readers of the trade publication “Armbanduhren” and the “Welt am Sonntag” newspaper put the classic Senator “Perpetual Calendar” in first place. In October the Manufactory joined the Swatch Group Ltd., an important step for the growth of the locally renowned brand into a global luxury brand. Glashütte Original is part of the Swatch Group group.
