Bonjour

En plus Laco était un des 5 fournisseurs de la Luftwaffe
« The German government demanded five manufacturers to build competent B-uhr watches which were both anti magnetic and able to be chronometer certified. It is believed that A. Lange & Sohne, a principal supplier of the time, could not deliver the watches in time for the amounts needed. The German government therefore brought the raw movements and cases to other watchmakers for mounting and regulating. The five companies that were assigned to build the watches were A.Lange & Sohne, International Watch Company, Laco, Stowa and Wempe. B-uhr was derived from the German word “Beobachtungs-uhr” meaning “Observation Watch”.
