Each watch is naturally one of one.The stone is cut into a thin disc before the dial components are assembled by hand. Applied indices with mirror-polished bevels create a precise contrast against the organic structure of the malachite, while BGW9 Super-LumiNova provides clear legibility after dark.Inside is the Swiss Made Sellita SW200-2 Power+ movement. Its 65-hour power reserve is complemented by improved winding efficiency and shock resistance. Each movement is individually COSC-certified and finished with Formex’s custom skeletonized rotor and thermally blued screws.The 41 mm stainless-steel case combines a screw-down crown with the patented Case Suspension System. Four integrated springs allow the case to respond to movement on the wrist while helping protect the movement from impacts.The stainless-steel bracelet is fitted with Formex’s patented butterfly clasp, offering on-the-fly micro-adjustment at 0, 3 and 6 mm without opening the clasp. Nylon, leather and rubber straps pair with the carbon fiber deployant clasp, providing 7 mm of gradual adjustment across six micro-steps. Every bracelet and strap can be exchanged without tools.Read MoreFEATURESSwiss Made Automatic MovementAn Automatic, also called self-winding watch, is a mechanical watch in which the mainspring is wound automatically as a result of the natural motion of the wearer's arm, to provide energy to run the watch, making manual winding unnecessary. All our Automatic movements are manufactured in Switzerland.ChronometerA chronometer is a watch that has been tested and certified to meet the most strict precision and accuracy standards. “Chronometer” isn’t just a name that any watch brand can print on the dial of its watches. It is an official nomenclature, defined by precise rules, which lay down the definition of the term “chronometer”, describing the categories, the test programme and the acceptable minimum requirements for wrist chronometers.
