The Essence Leggera is an ultra-light and uncompromisingly forward-thinking high-precision Swiss Made watch. With its subtle structure and a smooth, slightly silky feel, the 40g (1.4oz) case made of Carbon Fiber Composite was entirely developed in-house. Bezel and crown are made of scratch-proof Zirconium Oxide ceramic. Unique features, such as the patented Micro-Adjustment and Case Suspension Systems, will make the Essence Leggera wear exceptionally comfortable on your wrist.

Carbon Fiber Composite and Ceramic Case

The deep black color of the Formex Leggera case is achieved through material choice rather than surface coating like DLC or PVD. This ensures that your watch will always stay black. With a hardness that surpasses that of any traditional metal used in watchmaking, Zirconium Oxide ceramic is a scratch-proof material that will never show any signs of wear or aging. Being the most exposed components of a watch case, both the bezel and crown are made of this high-tech ceramic.

Suspension System

Since the beginning of Formex in 1999, the patented Case Suspension System has been an integral part of every single Formex timepiece. Its two main functions are:

  • absorbs shocks to protect the mechanical movement from heavy impacts
  • adds to the comfort on the wrist by adapting to the wearer’s movements

Modeled with high-performance bikes and racing cars in mind, the Formex patented case suspension system works by integrating four springs between the upper and lower watch case. The result is the ultimate shock absorption system designed to protect the mechanical movement and deliver unparalleled comfort to the wearer.

This patented case suspension system brings form and function together for Formex Swiss watches. It’s functional, it’s state of the art engineering and it’s unquestionably unique - all in one watch.


Under the hood beats a Swiss Made Sellita SW-200-1 automatic movement ensuring both accuracy and reliability. It comes in its highest quality grade ”Chronometer”, using top of the line components only found in Chronometer-grade movements. Each of the movements undergoes the COSC-certification process, a meticulous 15-day rate test to ensure extraordinary levels of mechanical accuracy and precision. Only the movements who pass the stringent assessment will be certified and engraved with a unique serial number. The movements’ power reserve extends to approximately 41 hours.


The updated Leggera collection comes with a series of multi-finished, in-house manufactured dials. Choose the extremely thin forged carbon fiber dial for a unique piece, as each dial has an individual pattern, created by machining the forged carbon fiber. The Arctic White and Mamba Green dials come with the Essence’s signature horizontal lines which are individually CNC-machined into the dial base. The Electric Blue dial has a mesmerizing sunray finish while the Cool Grey comes in glossy cement look. Hands and hand-applied indexes are mirror polished on the bevels to increase legibility during the day, while deep-filled grade A BGW9 SuperLumiNova emits a strong, blue lume in low light conditions.

Straps and Clasps

Formex has teamed up with WatchGecko to create a matching, all black NATO strap. For a perfect fit and comfort on the wrist at all times, the leather and rubber straps use the all-carbon Formex Deployant clasp with gradual, 7mm fine-adjustment system. All straps can be changed without the use of any tools and in just a few seconds.

For even more wrist comfort, Formex added their patented Carbon Fiber Composite Deployant Clasp that allows for 7mm of gradual fine-adjustment, allowing for a perfect fit on the wrist in all conditions and temperatures. The clasp is interchangeable and can be used on multiple leather and rubber straps.
