Vintage 1940s chronograph, retailer-signed "Löwenthal" on the dial (a period jeweler/retailer rather than the movement manufacturer, common practice for Swiss chronographs of this era). Steel case, two-pusher chronograph with 30-minute counter and running seconds sub-dials, tachymeter and telemeter scales printed on the outer dial. Dial shows age spotting/patina consistent with the period.

Recently serviced and keeping accurate time. Watch is fitted to a vintage expanding bracelet (please confirm if original — see photos).

Please review all photos carefully, especially dial condition, as they form part of the description.
