Grande Reverso Duo

Jaeger-LeCoultre SIHH 2011

The new Grande Reverso Duo is distinguished by its generous dimensions and by a dial design that has been entirely rethought to provide enhanced aesthetics and greater readability. The travel time zone is adjustable via the crown and located on the front side. In order to maintain the precision of the minutes and seconds, the adjustment is performed in one-hour jumps of the hour hand. To make everything user friendly, the date follows the travelers local time display and can jump both forwards and backwards. The home time display is located on the back.
The front shows the small seconds and the date in a central arc of a circle aperture, both clearly readable on the rectangular white dial combining vertical guilloché work and a Clous de Paris motif. Swiveling the case reveals the hidden face of the Grande Reverso Duo in the form of a double black dial displaying the time in a second time-zone complete with a 24-hour and day/night indication. This second dial featuresClous de Paris, horizontal guilloché work and satin-rushed/velvet surfaces.
The Grande Reverso Duo is powered by a new caliber 986 driving all six hands. The large balance oscillates at 28,800 vibrations per hour. The larger case size has also made it possible to increase the power reserve to a full 48 hours.
