Product Details
Palatial Big Date is elevated by a wide selection of dials, chosen among the most lavish and refined materials made available by nature : hard stones. Blue Lapis Lazuli, green Malachite and black Onyx offer their unique patterns and sheen to the polished allure of this collection.
Caliber JCAM52 is in a class of its own in the Jacob & Co. catalog. The large date and power reserve indication are sitting on top of a finely executed movement, chosen for its reliability. Developed in a hand-wound version, it does away with self-winding in order to shave off a precious few millimeters. This slimness is reflected in the overall design of Palatial Classic Big Date.
