Precision by Green ladies wristwatch

Precision by Gruen vintage silvertone ladies wristwatch, stretch band with abalone shell inlay. Watch hands turn with post, works but needs a new battery. Very little signs of wear, but has one barely noticable scratch on the quarts. This watch is beautiful and I hate to part with it but as a collector, there comes a time I must let go of some things. The abalone shell really sets off this watch and makes it a unique art-deco piece!
