The true beat seconds is a traditional complication at Arnold & Son, paying tribute to John Arnold’s 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.

The case and movement of this essential timepiece have been entirely revised, refined, and improved. With two inaugural limited series – one in rose gold, the other in platinum – Arnold & Son reaffirms its historic attachment to marine chronometers.
