CONTINUOUS INNOVATION

The quest for continuous improvement: This is Cartier’s ambition. An ambition where creative requirements became the driving force behind numerous watchmaking innovations. In 1904, the Maison created the first modern watch designed to be worn on the wrist. Since then, Cartier has filed over 100 patents and continues to file new ones regularly. These innovations converge with the expectations and values of each client.

PHOTOVOLTAIC PRINCIPLE

Also on the Tank Must, the Cartier Manufacture succeeded in applying the photovoltaic principle to the watch's dial without altering its aesthetics. A true technical feat, it relies on the delicate and invisible perforation of Roman numerals, whose openings let in light that reaches the photovoltaic cells hidden under the dial. It took four years for the development team to integrate this SolarBeatTM movement, with a lifespan of more than 16 years, into the Tank Must, the first to benefit from this technology.

AN INNOVATIVE NEW STRAP

The Tank Must watch introduces a supple strap made from an innovative material that doesn't contain animal products and guarantees a high level of quality and comfort.
It is made of 40% plant matter produced using waste from apples. The production procedure represents a step forward in preserving the environment by reducing our carbon footprint, as well as saving water and energy in comparison to manufacturing a calfskin strap.

INTERCHANGEABLE FOLDING BUCKLE

The interchangeable folding buckle is heavily inspired by the original Cartier folding buckle. Now patented, it is the result of a 3-year project in which each detail was painstakingly designed to provide very high levels of security, comfort and personalization. 

SMARTLINK

The SmartLink system allows the strap length to be adjusted by the owner without the use of a tool. Each SmartLink link is equipped with a push button that releases the fixing bar allowing for the removal or addition of links. A patent has been filed for this innovation.

QUICKSWITCH

With the QuickSwitch system, straps can be changed with a single push. Whether gold, steel or leather, an invisible mechanism located under the case allows for the strap color and material to be changed. A patent has been filed for this innovation.
