My wife's Kundo, of vintage about 1982 or earlier, has worked fine right up to the last month. Suddenly slowed & stopped as if batt. needed replaced. Did replace batt. but cannot restart. Pendulum is free & hands may be moved to correct time. But a new batt, correctly installed does no good. Of several batts. tried, all check out to the proper voltage. (Very similar circumstance as Clive, Dec. 2009. Quite a coincidence.)
