37-39mm
Arnold & Son fits the irregular swirling chatoyance of Namibian pietersite — the 'stone of storms' — into its 39.5mm × 7.82mm HM ultra-thin case, powered by the in-house manual A&S1001 calibre with a 90-hour power reserve. Each dial is naturally unrepeatable. Steel limited to 18 pieces (CHF 16,200), red gold to 8 pieces (CHF 27,100).
