Vintage Silver Souvenir Panel Bracelets c. unknown

These bracelets were purchased as a lot from an estate sale, the owner of which travelled to many areas around Thailand and the Middle East. Both have signs of wear and tarnishing, please refer to photos for condition, but are both fully functional, wearable and has an oxidized, antique look to them.

I am not able to date both of these bracelets but the gold over brass bracelet, with circular panels and Arabic writing, has a safety chain and a box clasp, which dates back to the 1920's. The second bracelet, with square panels and silver on metal setting, has a foldover clasp, which can date back as early as 1900's. No markings on both.

Measurements:
Gold, Middle Eastern bracelet: 8" length with safety chain, 1.5" diameter for the panels, box clasp closure
Silver panel bracelet: 6" length, .75" width and length for the square panels, with foldover clasp

Materials:
Gold tone on brass
Silver tone on metal
