Formex Essence FortyOne Automatic Chronometer Malachite 41 MM

$2,490.00 USD

The Essence 41 Malachite introduces the first natural stone dial to the Essence 41 collection.

Cut from genuine malachite, each dial carries its own pattern of bands, swirls and natural variations, ranging from vivid green to almost black. 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.

DIAL
Genuine malachite dial with naturally formed bands, swirls and variations ranging from vivid green to almost black. As every piece of malachite is unique, no two dials share the same pattern. Hand-applied indices and hands with mirror-polished bevels provide a precise contrast against the organic structure of the stone. BGW9 Super-LumiNova on the hands and indices ensures clear legibility in low-light conditions.

To keep your watch performing at its best, we recommend avoiding strong impacts, extreme temperatures, and prolonged exposure to moisture unless your watch is designed for water activities. After exposure to salt water, rinse the watch gently with fresh water and dry with a soft cloth.

For mechanical watches, regular wear helps keep the movement running smoothly. If the watch is not worn often, manual winding may be needed depending on the model. Quartz watches may require battery replacement over time.

Leather straps should be kept away from excessive water and humidity to preserve their appearance and longevity.

Because care recommendations can vary by brand and model, please refer to the manufacturer manual included with your watch for detailed operating instructions, water resistance guidelines, and service intervals.

Why We Carry This Brand

We carry Formex because the brand approaches watchmaking differently. There is real attention placed on comfort, finishing, and functional engineering rather than relying purely on heritage marketing. Their watches consistently overdeliver once you experience them in person.
