The hours are tucked into the foliage in the Olympic Automatic as the minutes churn at the bottom of a cascading waterfall, creating a serene forest scene at sunset. Illustrated by Kenneth Crane. What is a jump hour? A jump hour watch is a unique timepiece where the hour indicator does not slowly sweep across the dial. Instead, it displays the hour numerically in a small window and instantly "jumps" to the next number at the exact moment the 60th minute of the previous hour ends.
