The new version of Arnold & Son’s “DSTB” is alluring and intriguing timepiece is housed inside a 43.5 mm white gold case with gorgeous blue-finished dial (whichis actually part of the movement plate). It joins two other variations of the DSTB, which is part of Arnold & Son’s Instrument Collection. And like every other model from Arnold & Son, features an in-house mechanical movement. However this particular movement, the automatic mechanical A&S6003, is a true beat seconds (also known as a stop or dead beat seconds), which achieves the effect of a “ticking” seconds hand through clever mechanics. Further, Arnold & Son’s version showcases the true beat seconds’ mechanism entirely on the dial side. Not just the hands, but also the lever (specially shaped like an anchor), wheels and three palladium treated true beat seconds bridges are located in all their beauty on the dial side.
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.
The movement is finely finished with hand-chamfered and satin-finished lever and bridges, polished edges and fine circular graining and Côtes de Genève. The visible dial plate is blue PVD treated with large circular finishing, and screws with bevelled and mirror-polished heads. Complete with solid 22-carat red gold guilloché-decorated oscillating weight.
