Its transparency is alluring, and the perpetual movement inside displays well its playful spirit. Thus, to the great joy of aficionados of watchmaking and unusual writing implements, the Tourbillon Open Side pen continues to reveal – in the style of a genuine manufacture – the authentic gearwheels of a fragment of a watch's movement. And this time, the pen does so not only on its upper tip, but also sideways, as it were, on the upper lateral section. And the mechanism is visible through a sapphire crystal, ultra-resistant and scratchproof.

The leather attraction

A band of embossed crocodile leather covers the upper section, which adds to the grip comfort and produces the wonderful haptic feel of a noble and sensual material. The X stitching, inspired by the greatest French saddle-maker, hides away discreetly under a clip, whose robustness and suppleness are characteristic of the TF Est. 1968 brand, the Schmidt system that connoisseurs value so highly. This venerable attachment system will last forever. It is made up of 58 parts, giving an elasticity that prevents breaking. Its polished finishing avoids damage to one's pockets, the lapels of fine shirts or jackets made of delicate materials.

The Schmidt mechanism chosen pushes out the nib by turning the body of the pen. It is compatible with all the regular refills on the market.

Trendy colors, weapon of mass seduction

Each Tourbillon Open Side roller is numbered. And each one belongs to a color family that combines contrasts with esthetic exactitude. For instance, the rose gold hue, the product of the finest type of plating, melds with brown leather. The steel or gun-metal hue, a matt surface tending towards all-black with an industrial countenance, plays around with black leather. Today, in its 2014 version, the Tourbillon Open Side continues to seduce with vigor: it is soft to the touch, loves to be caressed, attractive to the hand, and makes writing flow. It is still in its noble casing, a start of, or a link in, a chain made up of an endless choice of cufflinks, key chains, or other writing implements of a horological nature.
