Founded in 1999, iconic Swiss brand Formex has carved out its place in the watch industry by crafting high-performance, robust, and timeless timepieces built to take on the most demanding conditions. Combining unparalleled know-how with relentlessly refined expertise, the brand brings obsessive attention to detail to every model - leveraging cutting-edge innovations and technologies, and handpicking every material that goes into each watch. Prepare to be captivated by the authentic charm and ultra-chic style of this extraordinary Forty One Mamba Green 0331.4.6300. From the Essence Leggera collection, this "Swiss Made" watch will become your go-to daily companion, carrying you through your greatest adventures with effortless fluidity. Draping your wrist in refinement and modernity from day to night, it delivers style, comfort, and elegance in every second. Its round case is built using Formex's patented suspension system for outstanding shock resistance and all-day wearability. Weighing 40 g, the case is crafted from carbon fiber composite and was developed entirely in-house with painstaking attention to every detail. It measures 41 mm in diameter, 11 mm thick, and 46.50 mm in length - dimensions perfectly suited to men's wrists. The bezel is secured by visible screws and elevated with a brushed finish, lending the whole piece a touch of elegant subtlety. Matching the bezel, the crown at 3 o'clock is crafted from scratch-resistant zirconium oxide ceramic. Its knurled design ensures a confident grip for easy adjustment of hours, minutes, and date. The dial is shielded from shocks and everyday wear by a sapphire crystal with an anti-reflective treatment, guaranteeing excellent legibility from every angle. On the caseback, the eight-screw caseback ensures water resistance to 10 bar. A transparent anti-reflective sapphire crystal opening gives you a front-row view of the movement housed inside.

The Dial

Made in-house, this round Mamba Green dial captivates with its textured design and clean finish. Its green base is crafted from forged carbon fiber, creating one-of-a-kind patterns that lend the whole piece a distinguished character. Horizontal lines and a brushed finish reinforce its timeless appeal while adding a dynamic edge. A slender seconds hand sweeps the dial, flanked by two polished baton hands indicating hours and minutes. Beveled gray hour markers with a polished finish are hand-applied around the dial, making it easy to read the time at a glance. The 12 o'clock marker features a double form for a striking visual, while the 3 o'clock marker is cut away to accommodate a date window with a black background. For flawless readability in the dark, hands and markers are coated with Grade A SuperLumiNova BGW9, emitting a powerful blue glow once the watch is plunged into darkness. A minute track graduated with fine lines runs along the rehaut for precise timekeeping. The brand signs the watch with its name and logo below 12 o'clock, marking the opposite end with the collection name "Essence" and the designation "Chronometer", along with the "Swiss Made" label at 6 o'clock.

The Movement

A COSC-certified automatic chronometer movement of exceptional quality brings this watch to life, driving its hands and date window with remarkable fluidity in any situation. Highly efficient, reliable, and accurate, the choice fell on the Sellita SW200-1 caliber. COSC certified, decorated, and fitted with a skeletonized rotor featuring thermally blued screws, it incorporates premium components such as a Glucydur balance wheel, making it highly shock-resistant and anti-magnetic. It beats at 28,800 vph - 4 Hz - and is fitted with 26 jewels. This Swiss mechanism delivers precise, reliable display of hours, minutes, seconds, and date under any conditions. Power reserve: 41 hours.

The Strap

Choose from three available straps, each giving this watch its own distinct character. Equally refined and on-trend, each option will keep up with every adventure while elevating any look, day or night.

Made by WatchGecko, the first strap is a NATO type - the go-to choice for divers and deep-sea enthusiasts. Crafted from braided nylon in a sleek black colorway, it pairs effortlessly with any outfit while delivering all-day comfort. Supple, timeless, and built to last, this strap features a black pin buckle in stainless steel for a secure hold throughout the day.

For the second option, the brand chose a black rubber strap that nails sport-chic style for any occasion. It combines comfort, flexibility, and durability - equally at home in the city or in the water. It keeps your wrist looking sharp from morning to night, secured by a deployant clasp crafted in carbon with a patented 7 mm incremental micro-adjustment system for a comfortable, secure, and perfectly dialed-in fit.

Ideal for wrist sizes between 16.50 and 19.50 cm, the third and final strap is crafted from Italian calfskin leather. It brings a touch of captivating refinement and modernity to your everyday look, finished in a rich green tone with tone-on-tone stitching for a polished effect. Its carbon deployant clasp features a patented 7 mm incremental micro-adjustment system, letting you wear your watch with ease and confidence - always perfectly fitted to your wrist.

It's worth noting that these straps are easily interchangeable thanks to their curved quick-release spring bars, and feature a lug width of 22 mm.

Water Resistance

This model is water-resistant to 10 atmospheres, or 100 meters. We're talking a genuinely water-resistant watch - ready to dive into aquatic life right alongside you. From puddles to the pool, this timepiece handles it all without breaking a sweat. Shower, bath, or serious swim? No problem. That said, our Ocarat watch experts want to be clear: despite its water resistance, this model is not suited for diving (professional or recreational) and is sensitive to high-pressure cleaning equipment. We also recommend keeping the crown and pushers clear during immersion.
