Art deco modernist bracelet

Genuine sterling silver art deco modernist bracelet. French. "crab" hallmark (means at least 800 / 1000 sterling silver). Silversmith hallmark unreadable for me....
Circa 1930. Very close to the very famous french makers described in the very nice book "Bijoux Art Deco et Avant Garde". Could be attributed to Jean Despres or Charlotte Perriand but more probably to Paul Brandt.
21cm long with clasp. 19cm without clasp. 3.5cm high. (8.25" - 7.5" - 1.4"). Excellent condition. Rare find.
