Heir to the noble British watchmaking traditions, the Arnold & Son TB88 is entirely in line with the prestigious creations by the famous 18th century English horologist John Arnold. It revives the magic of marine chronometry in a wristwatch size. The TB88 True Beat is distinguished by its Manufacture-made true beat seconds movement which is so impressive that it has been inverted or “turned inside out” so as to reveal through the front the beauty of its symmetrical “double 8” architecture, its 16 bridges, its large balance and its two barrels. Finally, true beat seconds mark time in jerking motion as a tribute to the first chronometer, n° 36, now displayed at the National Maritime Museum in London.
