The Eight-Day Royal Navy combines these historic features with a high-performance movement and two of the hallmarks of the antic Arnold & Son chronometers: the power reserve display at 12 o’clock and the “large” small seconds at 6. Inspired by the company’s historic chronometers, the watchmakers and designers at Arnold & Son set out to create a new in-house movement featuring an eight-day power reserve together with a digital date display. This top-flight movement features an unusually open design and meticulous finishing. It delivers further proof of the brand’s creative flair and is the 18th movement to be developed and designed in the company’s own workshops in just five years. The ability to create an unending series of new, customized in-house movements enables Arnold & Son to make the perfectly designed, uncompromising timepieces for which it has made its name.
