This is a actually a RARE OMEGA! This is the seldom seen reference 166721 LARGE 38mm. stainless steel watch with wide gleaming bezel and steel screw-back. The watch has its original and extremely fine (and uncommon) serpentine OMEGA bracelet with long buckle. The winding crown is original. This original dial looks absolutely amazing in person and has the most subtle patina. The handset is original as well. This amazing OMEGA is powered by the robust caliber 565 movemenmt which appears in the Seamaster 200 dive watch series from the same year. The movement has been cleaned and is keeping accurate time. This price is probably too low-I would act fast.
