Arnold & Son Instrument Dial Side True Beat – DSTB
Limited Edition of 125 PiecesThe “true beat” is a traditional complication of Arnold & Son, and this model pays tribute to the watches produced by John Arnold during the second half of his career, when he and his son were the first to develop marine chronometers that could be produced in quantity at reasonable prices. Those technically superior, widely distributed chronometers helped solve the problem of determining longitude at sea.
The newly developed in-house automatic caliber showcases the true beat seconds’ mechanism entirely on the dial side. Not just the hands, but also the lever, wheels and three palladium treated true beat seconds bridges are located on the dial side, also the true beat seconds lever is shaped like an anchor paying homage to Arnold’s maritime achievements.
