The listing, vintage Ritma Swiss 17 Jewels pendant watch, likely from the 1960s has ended.

Ritma Swiss 17 Jewels manual wind-up pendant watch. The watch is housed in a gold-tone, ball-shaped case with decorative star-like indentations. The watch face is silver with gold hands and markers, and it features the text "RITA," "INCABLOC," and "17 JEWELS." The term "17 Jewels" refers to the number of jewels (synthetic rubies or sapphires) used in the watch movement to reduce friction and wear on moving parts, a standard number for manual-wind mechanical calibers. "Incabloc" refers to a shock protection system for the watch movement. To wind the watch, the crown (the small knob on the side) needs to be turned clockwise until some resistance is felt, usually about 20-30 turns. Overwinding should be avoided as it can damage the mainspring.
