Caliber JCAA45 is an entirely new creation, designed specifically for The World Is Yours Dual Time Zone Tourbillon. To the original, defining dual time zone complication, it adds a central 30-second tourbillon. Its upper bridge is made of sapphire and the ensemble is topped by the compass rose that's an integral part of the collection.
What's more, and for the first time in the history of Jacob & Co. movements, this caliber is wound automatically by an off-centered micro-rotor. This special architecture dramatically reduces height, and allows for a 65-hour power reserve.
