I have no SEIKO, but I am always amazed what the can do for small money! I know from Seikos runnig 20 years, something what we cannot say about some "so called" luxery brands. Best Walter
"5717" one push chronograph which was introduced for the first Tokyo Olympic in 1964. Very, very nice! Hope this one still runs as it is supposed to! Thanks for showing it here! Ken
