Antique ladies Waltham Orb Rock Crystal Pools of Light or Glass Ball Skeleton Back Watch Pendant. It has the skeleton back where you can see the gears. It is a manual wind movement and says nine jewels, serial # 30726802 dating to 1940, model L-8.75, grade # 879, size 8.75L, Movement is Hunting with a Breguet hairspring, Adjusted and all this was found doing some research online. Outer Gold rims tested 10k, not the inner lips - see last picture of where it tested 10k, however since it is not stamped anywhere I cannot say for sure.
It has a tulip link on top, and it dangles from a 1/20 14 kt gold filled chain that is 20 inches long. The watch runs and keeps time but I have not had it looked at nor cleaned. Total length of the watch from the tulip link to bottom is about 1 1/8 inches, the orb part is about 7/8 inches across to the end of the winding stem. In very good condition, some light wear and discoloration on the top tulip link and jump ring, the slit where you open the back shows scratches from being opened and closed over the years and note it is hard to open, the crystal or glass has some light surface wear and the pretty face is clean, and it runs and keeps time but I can't say it'll keep running since I did not have it professionally looked at.
