TAVAT believes that there is somewhat of a creative combustion that occurs when you place top-of-their game designers, master craftsmen, and expert manufacturers together. Ideas and intent collide and fuse, and something new and wonderful can take form. That something wonderful is the engineering behind the Tactile hinge.

TAVAT is taking the greatest eyewear-making traditions to more stylish and sophisticated heights and is pioneering a new take on "traditional eyewear."

The Tactile hinge is an icon of timeless elegance: simple, functional, iconic, and as the name suggests: preceivable to the touch. Just like a fine Italian wine, this hinge improves with age.

How does it work?

Hidden inside the main body of TAVAT's Tactile hinge is a spring and piston.  The spring pushes the piston forwards which interacts with the teeth of the gear which creates the unique sound you hear and gives the signature feel when you open and close our frame. Over time, the teeth of the gear smooths giving a more fluid feel. This hinge has been tested for 30,000 opening and closing operations, equivalent to 8 years continuous use, and still maintains performance 

External Cam (Ex-Cam) *Non-Flex

TAVAT’s Signature Ex-Cam Hinge guarantees a high-tech mechanical precision, from opening to closing there is a fluid motion, accompanied by a burst of energy that gives the whole a feeling of precision and quality. Thanks to this innovation, TAVAT was nominated for the Silmo d'Or award in Paris, on October 2010.

How does it work?

All of this is allowed due to the study of a sliding cam, it’s relationship to the double wires connected by the barrel and the insertion of a spring hidden inside the hinge working in compression over time.

This precise engineering, favours the temple to open and close with a typical “click” sounding movement, which gives a high-quality and technical print to the whole frame. 

External Cam (Ex-Cam) *Flex

TAVAT'S  "Super Elastic Alloy" is not your typical "flex."

Taking advantage of space age technology, a super elastic alloy, used in Satellites when they reach the orbits and must unfold their mirrors and antennas has been adapted to the Ex- Cam hinge to make it perform as a spring without degradation.

The frame retains its original Iconic yet functionally designed hinge and incorporates this super elastic material which allows us to retain the original design and offer a flex hinge at the same time. 

The flex comes from the "Super Elastic Alloy" we have used for the part connecting the temple block to the front cylinder. The alloy was originally developed by NASA®, for the deployment of the very long antennas and solar panels, which are opened once in orbit.
