Notes

The Hatot self-winding system, called “Rolls”, made it possible to adapt a self-winding mechanism to both rectangular wristwatches and small-sized lady’s writswatches. Most often found in gold plated or chromium plated cases, 18K gold cases such as this lot are extremely rare.

--

Movement based on the French invention patent No. 704 910, delivered on January 11, 1930, to Société Anonyme des Etablissements Léon Hatot, Paris (France), for a “Perfectionnements aux montres dont le remontage est assuré automatiquement par les déplacements et secousses qu'elles subissent, et aux systèmes analogues”.
