Dial side true beat

The true beat seconds is a traditional complication at Arnold & Son, paying tribute to John Arnold’ marine chronometers. The DSTB (Dial Side True Beat) self-winding movement showcases the true beat seconds’ mechanism entirely on the dial side. Not just the seconds’ hand but also the lever, wheels and bridges; making the watch even more alluring. The true beat seconds lever is shaped like an anchor – paying homage to Arnold’s maritime achievements.
