"

The story of bringing to life a Legend...”

CHAPTER ONE

Inspiration: WHERE IT ALL STARTS

At Styljoux Workshps the fundamental step in the birth of a Styljoux writing instrument is the idea. It might come as a surprise, but we simply do not make a pen because there is demand on the market. We do not analyse the market to see what the market wants and we respond with an appropriate product.

At Styljoux we regard the process of making a writing instrument as a creative process akin to creating a sculpture or a painting. The inspiration is crucial. The product has to be born. It has to have an artistic quality which uplifts the creator and resonates with the viewer.

The genesis of the original Styljoux collections Le Calibre and Flamingo is such a process. A form and aesthetics that translates a certain state of mind. The collections have a language of their own. A powerful body, for Le Calibre, that pursues elegance and modernity. A fluid and timeless shape for the Flamingo. The emotion they transmit is all too familiar to the Styljoux aficionado.

This heritage has to be guarded and nurtured. Hence the House of Styljoux will passionately continue to refine our artistic vision whilst relentlessly pursue technical and material innovations.

CHAPTER TWO

SKETCHING

Any new idea starts in our Ideas Lab. This is the very heart of our brand. The place where we set to evolve our classic designs into new expressions. To facilitate the design process we bring together under the same roof designers, material and micromechanics engineers and craftsmen.

Creativity is required primarily at this stage. No idea is rejected, but carefully considered and refined. The designers experiment with shapes, materials and colours. A regular and intense exchange takes place with the engineering team to see what is possible from a technical point of view. Craftsmen are consulted in regards to finishing options or manufacturing possibilities.

New or improved mechanics are explored at same stage. As a unique manufacturer of precision movements and mechanical components we pay close attention to our technological side. Complex movements like the weight adjustment mechanism are designed here.

CHAPTER THREE

COMPUTER DESIGN

Once the sketching is done and the direction agreed the design is computer programmed. Using powerful CAD software the concept is developed into a more concrete vision.

The shape of barrel parts or components can be very complex. Unlike most pens on the market Styljoux writing instruments often have a complex 3D architecture. Each element has to be individually programmed to exact specifications. Any error at this stage will result in unusable parts. Only perfectly calculated dimensions and a superior engineering will result in a flawless finished product. Potential engineering flaws are tested at this stage in a virtual environment.

CHAPTER FOUR

PROTOTYPING

Rapid prototyping is initially used. Many different resin and aluminium versions are produced. A sense of weight and proportion is acquired.

Furthermore a 10:1 scale model is produced from the CAD model. This draws attention to more subtle issues before the smaller, pre-production prototype version is made. It's critical stage, when most technical flaws are indentified and rectified. Any uncovered flaws may result in future costs and delays.

Depending on the complexity of the movement, one to five prototypes are performed to validate the mechanism. It takes on average one month for watchmakers and 3D engineers to create a finished prototype.

Once the design team and engineers and pleased with the result, the prototype is sent for a small batch production. This is when the pre-production pieces are made. They are made employing 5 axes CNC machines capable of using up to 24 different tools to machine parts at incredible tolerances. For barrels the maximum acceptable tolerance is 0.01 mm whilst for parts is 0.001 mm.

CHAPTER FIVE

TESTING

Once manufactured, the pilot batch is subjected to a brutal series of 35 tests. They last a few weeks and simulate conditions in all environments similar to what a pen would experience over the course of its long life. Issues discovered at this stage are solved and a new pilot batch is produced. Once the new batch passes all tests without further problems, is the model ready to go into series production.

Among the most important test are impact, abrasion, climate, corrosion and UV and practical tests.

Impact test. One of the most extreme is the 'chapuis extreme'. The pen is relentlessly rolled and shaken inside a tumbler for hours and subjected to continuous impacts from all sides.

Here, the pen is shaken around inside a small container for hours on end, subject to knocks and impacts from all sides.

Abrasion test. Components and parts are repeatedly subjected to friction forces from all angles. The aim is to ensure that moving parts will resist the test of time without breaking because of material fatigue. Each Styljoux writing instrument has an projected life expectancy of at least 50 years.

Climate test. Pens are tested inall thermal condition present on Earth. From the extreme cold of Antarctica to the humid and hot tropical environments. Pens are placed in a test container where, over a period of days, they are exposed to sudden and prolonged changes of temperature and humidity.

Corrosion and UV. To ensure that material do not develop signs of corrosion materials are submerged for a fortnight in a cocktail of aggressive salts dissolved in fluid. Strong UV rays are directed on the surface of the components to ensure that there is no change in coloration.
