The DSTB 42 Red Gold is the perfect demonstration of what Arnold & Son does best: technical watchmaking that is elegantly showcased.

The elegance of a unique clock ticking
A bold reinterpretation of time
With the DSTB 42 Red Gold, Arnold & Son revisits one of its most iconic models. This exceptional watch highlights its true second mechanism – also known as a dead second – directly on the dial, a watchmaking feat that combines precision technology and spectacular design.
With a 42 mm 5N red gold case, this limited edition is in the tradition of the marine chronometers developed by John Arnold for the Royal Navy. Its deep blue dial, obtained by PVD treatment on a sunburst finish, gives this piece a striking aesthetic, where every detail is designed to captivate the eye.
A true seconds mechanism on display
The distinctive feature of the DSTB 42 Red Gold is the true seconds display directly on the dial. Usually hidden at the heart of the movement, this mechanism is here exposed under three openworked and finely chamfered red gold bridges. The characteristic lever, in homage to historic marine chronometers, drives the large seconds hand with rigorous precision, illustrating the unparalleled expertise of Arnold & Son.
A new-generation caliber
The DSTB 42 Red Gold is powered by the A&S6203 caliber, a manufactured self-winding movement optimized for performance and finesse. Only 5.54 mm thick, it incorporates a 22-carat gold oscillating weight and offers a 55-hour power reserve. Its regulating organ beats at a frequency of 28,800 vibrations per hour, guaranteeing remarkable precision.
A perfect balance between tradition and innovation
With its case resized to 42 mm in diameter, the DSTB 42 Red Gold is part of a contemporary approach to fine watchmaking. More ergonomic and refined than its 44 mm predecessor, it retains all the majesty of its watch display while being more comfortable on the wrist.
This limited edition illustrates the expertise of Arnold & Son, a company that perpetuates the heritage of Swiss haute horlogerie by reinterpreting the major chronometric advances of the 18th century. The DSTB 42 Red Gold is not just a watch: it is a mechanical work of art, a tribute to time and its absolute precision.
