Otherwise known as Dial Side True Beat.  Here's the scoop, straight from Arnold & Son -

The DSTB is part of the Instrument Collection and, like every other model from Arnold & Son, features an in-house mechanical movement. The true beat seconds is a traditional complication of Arnold & Son, and this watch 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 reflected Arnold & Son’s commitment to exceptional precision and solved the problem of determining longitude at sea.

Upholding that legacy, Arnold & Son’s master watchmakers thrive on creating complicated movements for exquisite timepieces. Such is the case with the DSTB watch, a truly innovative technical and architectural achievement. The newly developed automatic movement 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 in all their beauty on the dial side. Making the watch even more alluring is the fact that the true beat seconds lever is shaped like an anchor – paying homage to Arnold’s maritime achievements.

The true beat seconds are superbly indicated via a large sapphire dial that occupies the top left portion of the dial at 11 o’clock. At the 4 o’clock position, a domed and white lacquered subdial indicates the hours and the minutes via blued hands. These generously proportioned, overlapping indications translate into a stunning three- dimensional dial.

This restructuring of the intricate mechanism yields a concept not achieved in the watch industry heretofore. The self-winding calibre A&S6003 has 229 components. In true Arnold & Son style, the palladium treated movement features Haute Horlogerie finishing with hand-chamfered and satin-finished lever and bridges, polished edges and fine circular graining and Côtes de Genève rayonnantes. The visible dial plate is blue PVD treated with large circular finishing, and screws with bevelled and mirror-polished heads.

The magnificent timepiece is housed inside a 43.5 mm 18-carat white gold case with anti-reflective sapphire crystal and caseback for viewing the superbly finished movement and, complete with solid 22-carat red gold guilloché oscillating weight. This edition of the DSTB will be limited to 125 timepieces – underscoring the brand’s commitment to exclusivity and excellence.
