Omega DeVille prestige automatic chronometer. Reference 4500.31. 1120 movement. I have had this watch for almost five years. Service history unknown. The watch keeps good time and no issues. There are two nicks on the case at the 9:30 and 10:30 locations. The hands do have some pitting. But, the dial is perfect. And of course a black dial watch never goes out of style. Original deployment bracelet with extra links. $900 USD. I will cover insured shipping within the 48 continental US. International shipping at cost.
