Wempe Glashütte I/SA watches

Wempe Glashütte I/SA is the watch brand of Wempe, the German watch and jewellery retailer established in 1878. Wempe's connection with Glashütte dates to 1939, when Herbert Wempe and Otto Lange founded the 'Glashütte Observatory' working group. In January 2005 Wempe acquired the Glashütte observatory, renovated it and opened its own watchmaking training centre there.

In 2006 Wempe launched its own wristwatches under the Wempe Glashütte I/SA name, in two collections, Wempe Chronometerwerke and Wempe Zeitmeister. The Chronometerwerke line includes in-house calibres assembled and finished in Glashütte, and the watches are chronometer-tested at the observatory according to ISO 3159. The Iron Walker collection followed in 2020.
