Vintage Milos 10k RG art deco pendant/brooch watch

Vintage Milos 10k rolled gold art deco pendant/brooch watch. Possibly from the 30's or 40's. At its widest point including the loop to attach to a brooch or necklace it is 42mm. The glass is carved on its sides like a diamond and the caseback has a small stamp that says "10K.R.G". The dial has the name Milos just below the 12 and at 6 o' clock it has a sub-dial that displays seconds. Below the seconds dial it has a marking that reads "swiss". This is a manual wind watch and when I wind it, it does run and seems to keep the time. This would make a great gift for someone into the art deco aesthetic, could be used as a brooch, necklace pendant or even a wristwatch with a little creativity. As this is a vintage watch and I can only test it by winding and seeing if it runs and keeps time I cannot guarantee anything in the long term as with any vintage watch of this age.
