Vintage Tango Sterling Closed Bangle

This vintage bangle bracelet is made of sterling silver and does not have an opening. I'm not sure of the name for this chain type, but the bracelet looks like the letter S was made into a chain and flattened. S chain? The bracelet is stamped on the inside and says Tango, 626, and another stamp I can't read. I had to do some research, but it seems 626 is another way of saying 925... today I learned! This bracelet has some wear but is in good condition overall. Dimensions (across): 7.5cm x 7cm / 3" x 2.75" Width: 7mm Weight: 18.62g
