Retrograde clock

Regatta watch with retrograde displays

Complication with two additional seconds leaves (small 142 ° sectors): After the right hand has counted the seconds backwards from 0 to 30, it jumps back to 0 and the second second hand starts at the same time from its rest position at 30 seconds to run up to 60 . In the clockwise direction, however, the minute and second on the small raised leaf and all three types of hands on a separately adjustable, large central time display with fifths of a second run.

A retrograde clock , also known as a retrograde clock, runs counterclockwise . Such clockworks are offered for special clocks with an attached mechanism (e.g. shadow clocks) or for fun clocks. Clocks with Hebrew lettering are or were retrograde, according to the reading direction of Hebrew.

Well-known watches with retrograde display elements include the Timex Yacht Racer regatta watch , the Swatch Irony Retrograde with a counterclockwise stopper, and the Longines Master Collection Retrograde with three (day, date, 2nd time zone) and four (day, date, second, 2nd time zone) ) retrograde functions or the Maurice Lacroix Masterpiece Rétrograde with retrograde date hand.

For special functions such as B. Countdown or chronograph, there are also individual receding hands ( retrograde display as a complication ). In the case of a complication known as a retrograde display , a pointer showing the time or date moves over a segment of a circle (1 to 12 or 1 to 31) and jumps back to its starting position when it has reached the end of the segment scale.
