Dial signed, in good conditionDIAM: 41 mm THICKNESS: 13 mmNOTE: The production of chronographs was intense in Germany in the 1940's. Beside the Glashutte watchmaking industry, there was Schwenningen am Nackar, where the Company HANHART created a chronograph of high prestige, with one or two pushbuttons. This example of single button chronograph was used by almost everyone, from the Wehrmacht to the Luftwaffe. But above all, the War Navy had the major use of this watch.
