I bought the Casio Duro and now it's on week three of it's "accuracy acceptance". If it's over a second a week off, it's going back. So far, it looks good. All our watches, about 30 between us, are quartz and all but one are 5 seconds or less a month. Even my wife's very old fashion watches (Avon) manage to stay under 8 seconds a month. Two newer ones think they are Atomic time pieces and stay within a second a month. One of them is a Citiizen Tough. So.....my question....
