I believe these bracelets were produced by the Bengel Company of Germany and retailed in France by French companies. This is a blue galalith and chrome gate bracelet. This piece has appeared in many art deco jewellery books. I have been fortunate to obtain five of these bracelets and they are all old unsold stock items. So I can currently offer these in red, purple, orange, red and black.
It measures 1 inch (2.5cm) wide and 7 inches long (17.5cm) and so will fit a small to medium sized wrist.
In excellent vintage condition.
