The design of the present bracelet is believed to have been inspired by the Maginot Line, a system of defensive fortresses constructed in northeast France to divide French and German-occupied territories during WWII. The fortresses were characterized by their linear design and thick concrete walls, many of which were built underground, giving them a mound-like appearance. Outside the main structures, a series of “dragon’s teeth,” similar in shape to the bracelet’s sapphire-set links, were arranged to impede the procession of German tanks.

A bracelet with links of similar design is in a photograph of Mauboussin's vitrine at the World's Fair in New York in 1939. This photograph can be seen on page 118 of Mauboussin by Marguerite de Cerval.
