By working closely with aerobatic pilot Nicolas Ivanoff, Hamilton has managed to develop groundbreaking complications such as a cross-wind calculator and a world-timer function, as well as including innovative and high quality materials like weightless aluminium in its timepieces across the collection. These technical advances don’t, however, come at the expense of style, as sleek and refined case constructions are teamed with attractive dials and comfortable and varying straps or bracelets. Once again, Hamilton has used its past in order to shape its bold and exciting future, with the results being a visually and technologically stunning range of timepieces.   The Brand: Hamilton Since its foundation in 1892, Hamilton has amassed a reputation as the ultimate provider of accurate timekeeping combined with stylish design. In 1912, the company began producing pocket watches so accurate that they earned the title of “The Watch of Railroad Accuracy.” This lead to the brand being bestowed with the prestigious rank of supplier to the US military at the outbreak of both world wars, and American involvement in the Second World War saw the pioneering Hamilton Marine Chronometer become an invaluable navigational tool for the U.S. Navy. Hamilton in the post-war years has been defined by its unique and exclusive relationship with Hollywood. Beginning with the 1951 Frogman watch, Hamilton watches have featured in over 450 films, including on the wrist of Elvis Presley in 1961’s Blue Hawaii, in 2001: A Space Odyssey, and more recently in Interstellar and The Martian. In 2003, all production and the company headquarters were transferred to a state-of-the-art facility in Biel, Switzerland. Still a global force within the timepiece industry, Hamilton watches offer an unrivalled combination of storied American heritage, Swiss internal workings and a touch of Hollywood flair.
