An Equation Of Time (aka EOT) complication indicates the difference between "true" solar time (that of nature) and "mean" solar time (that of man). As the earth orbits around the sun in an elliptical (oval) shape & the axis is tilted - there are only 4 days a year when the day is exactly 24 hours long April 15th, June 14th, September 1st and December 24th. All other days of the year the days are shorter or longer - depending in the position of the earth. This watch will show the difference between the "mean" time & the "true" time. Since the of the days are fixed year after year (at the same location) a watch can be manufactured to replicate the correction via a shaped cam which elongates & shortens the days accordingly.Decorated skeletonized rotor - can be personalized for an additional cost, the standard version has the AP letters.These watches need to be set at the factory in Switzerland to your exact location - this location will be printed on the rim of the EOT bezel ring. Delivery for this watch can take between 12-24 weeks. Orders for this watch are considered "special order items" & cannot be canceled. A 50% deposit is required to place an order for this watch.

Equation of Time (EOT) Complications - all of these complication are synchronized to the perpetual calendar with no corrections necessary:
Sunrise sub-dial at the 3 o'clock position - advance & reverses as necessary throughout the year.
Sunset sub-dial at the 9 o'clock position - advance & reverses as necessary throughout the year.
