In addition to the perpetual calendar complication and the power reserve indicator, the watch also boasts a very unusual feature – perpetual equation of time. A timepiece fitted with an equation of time complication displays the difference between mean solar time – our civil time based on a conventional twenty-four-hour period – and the true solar time, which varies with the earth’s irregular orbit round the sun. Mean solar time runs up to 14 minutes ahead of it, as is the case on February 12; or up to 16 minutes behind true solar time, as is the case on November 3. The equation of time complication is an extremely complex mechanism which is rarely featured in a wristwatch. While collectors nowadays look for watches that are rare and have an unusual feature, the Breguet Classique Grande Complication is an awe-inspiring example which will surely add value to any collection.
