New Limited Edition Swiss Swatch SISTEM51 CREAM SUTM400 Automatic 42MM Leather

Essentially NOS Sistem 51 Automatic. Purchased in Swatch's NYC boutique and basically never have worn it except to try on. Pristine condition. Box is a bit worn from age. Great color that can be worn with anything. Super light and comfortable. Really a nice watch and interesting automatic movement. Good luck!
