Product Details
Palatial Big Date is the one Jacob & Co. collection that pays a clear tribute to watchmaking classics. The elegant 42-mm case is elevated by its lug design, curved and gracious, which turns Palatial Big Date into an everyday-wear timepiece. The choice of a slim case of contained dimensions goes hand in hand with a sense of symmetry : the large date balances the power reserve indicator at 6 o'clock.
Palatial Big Date is further 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.
