What to know
Formex created the Essence 41 Space Ghost around a genuine slice of Muonionalusta meteorite. Its natural Widmanstätten structure makes every dial different, while a proprietary rhodium treatment protects the iron-rich material and sharpens its silvery appearance. Thermally blued hands and markers add contrast inside a 41mm steel case measuring 46.5mm lug-to-lug and 10.6mm thick.
The model also debuted Formex’s intermediate steel Essence size, combining a screw-down crown and 100-metre rating with the brand’s suspended inner case. A redesigned bracelet clasp provides 0mm, 3mm or 6mm adjustment on the wrist. The COSC-certified Sellita SW200-2 Power+ automatic movement delivers 65 hours of reserve, and the annual production batch is limited to 150 pieces.
