Formex Perfects Its Bestseller: A Look at the New Essence 39mm COSC Watch

August 28, 2026

A Refined Evolution of a Modern Classic
Since its introduction in 2018, the Formex Essence has become a cornerstone of the Swiss watchmaker’s contemporary collection. As the first new model launched under CEO Raphael Granito after the brand’s 2016 relaunch, it has consistently been a top performer. The 39mm stainless steel variant, in particular, holds the title of Formex’s best-selling watch. For 2026, this beloved model has been refreshed with a series of significant enhancements. Rather than reinventing the wheel, Formex has chosen to refine its proven recipe, ensuring the updated Essence 39mm retains the core attributes that have made it a favorite within the enthusiast community while elevating its overall quality and user experience.

Enhanced Case and Bracelet Functionality
The new Formex Essence 39mm Automatic COSC maintains the celebrated dimensions of its predecessor, featuring a 39mm diameter, a slim 10.5mm thickness, and a 20mm lug width. The case, crafted from durable stainless steel with sapphire crystals on both sides, continues to house the brand’s patented case suspension system and guarantees 100 meters of water resistance. The most notable upgrades, first introduced on the 2025 limited-edition Essence 41mm “Space Ghost,” have been integrated here. These include a more robust screw-down crown for added security and an improved butterfly-style clasp for the steel bracelet. This advanced clasp now incorporates a sophisticated extension system, allowing for 6mm of tool-free, on-the-wrist adjustment for a perfect fit.

Upgraded Movement and Aesthetic Options
Beyond the external refinements, the 2026 Essence 39mm boasts a significant internal upgrade. The timepiece is now powered by the Sellita SW200-2 Power+ automatic movement. While based on the familiar SW200-1 architecture, this caliber features reworked components for greater efficiency. The result is a substantial increase in power reserve to 65 hours, a tangible improvement over the previous generation. Each movement is COSC-certified, assuring chronometer-grade accuracy. At launch, the watch is available in three striking dial colors: Formex’s signature Blue, a crisp Alpine White, and a warm Radiant Bronze. Buyers can pair their watch with the updated stainless steel bracelet or choose from various straps in rubber, nylon, or leather, all equipped with Formex’s clever carbon-composite deployant clasp featuring its own micro-extension system.

A Subtle but Significant Improvement
At first glance, the changes to the Essence 39mm might not be immediately apparent, which is precisely the point. Formex already had a highly successful and well-regarded design. The 2026 update focuses on subtle yet meaningful improvements that enhance durability, comfort, and performance. By incorporating a longer power reserve, a more secure crown, and a superior clasp mechanism, Formex has thoughtfully elevated its flagship model. These upgrades successfully build upon a winning formula, solidifying the Essence 39mm’s position as a leading choice for collectors seeking exceptional value and Swiss engineering.
