On August 1st 1785, the Count of Lap\u00e9rouse set sail with two ships, 220 men and five chronometers by Ferdinand Berthoud, Watchmaker and Mechanic by appointment to the French King and Navy. For two years, he charted half of the world with the help of his sextant and chronometer navigating instruments. The latter were made of bronze, a sturdy and stable material that can nonetheless also become oxidized \u2013 as confirmed by the sextant recovered on the spot where Lap\u00e9rouse\u2019s ship foundered, in the South Pacific. This was the tool that inspired the theme of the Chronom\u00e8tre FB 1R Edition 1785. This chronometer, endowed with a tourbillon and constant force ensured by a fusee-and-chain transmission system, has an octagonal case resembling a marine chronometer as glimpsed between the spokes of its gimbals. It features an architecture similar to that used by Berthoud and a regulator-type display. The 1785 edition is a series of five watches, all made of bronze. Each has been oxidized using a different technique and yielding a distinct aesthetic result, ranging from yellow through classical green to deep chestnut brown. All these shades have been stabilized and are certified non-toxic. Each is unique in terms of its appearance and the approach behind it.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sailing the high seas owes everything to the bronze marine chronometers of navigation\u2019s golden age.
