Arnold & Son DSTB for Only Watch 2019

Arnold & Son for Only Watch 2019

The dial-side true seconds mechanism already marked the DSTB out as unique. But the Only Watch edition also allows its owner to personalise the complication's characteristic true seconds counterweight.
Arnold & Son’s DSTB model calls on the watchmaking science of John Arnold, a British watchmaking genius active in the late 18th century. Throughout his career, he focused his efforts on the quest for extreme chronometric accuracy. John Arnold garnered renown in part for his marine chronometers, which naturally featured a dead-beat seconds mechanism – more favourably known as a true seconds.


Instead of incorporating it into the movement, the DSTB places the entire true seconds mechanism on the dial side, making it easy to understand and, above all, spectacular. The components of this unusual display can be found under a large transparent sapphire circle punctuated with light sky-blue indexes.

Arnold & Son has gone further still in the pursuit of uniqueness. The winning bidder for the DSTB Only Watch will be invited to choose the shape of the true seconds counterweight to replace the anchor-shaped piece. Arnold & Son will produce the component in question and incorporate it into the watch. The piece will then be both personal and unique.
