Elegant Vintage Favico "10k RGP Bezel" Watch With Extra Strap

Elegant Vintage Favico "10k RGP Bezel" Watch With Extra Strap. Likely from the 1960s in art deco cocktail style. Gold rolled plated I’m not sure what parts are GRP? The back plate is stainless steel. Condition is fair with signs of wear, scratches on all sections of the watch and bands. Movement: Manual wind (hand-winding) mechanical, not quartz. Does wind and I can hear it ticking but it does not keep proper time. So it will need to be looked at. Likely needs cleaned. Feel free to contact me with any questions. Thank you.
