The HM by Arnold & Son showcases a dial crafted from pietersite, a decorative mineral known as the “stone of storms,” evoking Cornwall’s tempestuous skies and foaming waves. Available in 18-carat red gold or steel, the ultra-thin 39.5?mm case houses a manual-winding A&S1001 calibre, 2.70?mm thick, offering a 90-hour power reserve. Limited to eight gold and eighteen steel pieces, the HM displays only hours and minutes, reflecting understated elegance. Paired with a matt blue alligator strap, it celebrates both English watchmaking heritage and the spirit of those who navigate life’s storms with grace.
