The Book Tower, an Italian Renaissance-style skyscraper located in the heart of downtown Detroit, is one of the city’s oldest and most spectacular architectural highlights. The Shinola Book watch takes its signature ovalene shape from a remarkable third-floor skylight, a stunning feat of glass and iron work that bears witness to the glory of Detroit design, history, and craft. This edition of our Book watch features a dial of lapis lazuli, a gemstone prized around the world since antiquity for its intensely deep blue hue. Crafted from stainless steel with a PVD gold plating and a matching five-link bracelet, this petite 25mm watch is a work of art and wonder. Engrave the case back of the Book to make it uniquely your own.
