Casio Pulse Watch JP-100W - this Casio pulse sensor enabled JP-100W was released in 1987. The watch is in amazing original unrestored condition. The resin case and crystal are in great shape and have very light scratching typical of a gently worn watch of it's age. It comes on a vintage made in Japan genuine Casio strap. I'm not sure if it's original but it would be period correct. Please review all the pictures in the gallery. The battery is resent but I did notice the gasket has been previously damaged when it was jammed between the case and case back. Pulse sensor and all functions are working.
