Respectable Member MyVintageOmega Apart from the Olympics time-keeping that Omega have always excelled in, I find that even the old Omega wrist-watches, whether or not they come with the Chronometer ratings, have always been more accurate than some other watches of greater popularity, for instance Rolex. For the price, Omega can be considered as the best value for money, wrist-watch. Thank-you.
