Arnold & Son HMS1
The Arnold & Son HMS1 is part of the company’s Royal Collection, which epitomizes the maritime roots of the company and its namesakes, John Arnold and his son. The hand-wound AS1001 proprietary movement powers the HMS1, and the see-through caseback reveals its superior design and superlative finish. The watch’s phenomenal 80 hour power reserve comes from a double barrel design, which also buttresses the amplitude of its power and thereby its accuracy. With classic marine chronometer styling, the thin 40mm HMS1 has more than meets the eye.
