This piece is of extremely high quality and in very good condition. It is very unusual to find a watch with minute repeating and chronograph that bears the poinçon de Genève mark on the movement, signifying that this watch has been awarded a chronometer standard rating. Any added complications in a watch mechanism can adversely affect the timekeeping, thus this watch is highly unusual in achieving chronometer standard timekeeping.
