“The Jardur Import Company was the exclusive importer from Switzerland of
the well-known Jardur aviation waterproof Bezelmeter chronographs and the Jardur aviation waterproof wrist-watches. The Swiss cases containing the fine quality 17 jeweled movements. The Jardur precision timers were especially designed for pilots, and incorporated outstanding features necessary and desirable in all flying procedures.”
The specialization of the JARDUR as an instrument shows up in other ways as well. JARDUR sales and distribution were specifically directed to Post Exchanges and Ships Service Stores. Thus, virtually every one of these original chronographs has a guaranteed history of military service.
