These 35.5mm. (full-sized) Omega Seamaster Chronometer watches are becoming difficult to find. This is a splendid example, with a completely original dial and Baton hand-set. The dial displays some subtle patina that is rather pleasing to the eye. The beads of rice bracelet is original and will fit up to 7.5 inches. The automatic winding CHRONOMETER GRADE 23 jewel movement was just cleaned and is accurately keeping time. These watches are uncommon, as they are similar to the CONSTELLATION line of watches, due to their chronometer grade movements (this one adjusted to 5 positions like the CONSTELLATION). These are becoming hard to find. This is the only watch you will ever need-and looks fabulous on the wrist!
