BOC Tourbillon

In watchmaking, a tourbillon, also called a “rotating cage”, is a horological complication, added to the escapement mechanism, intended to improve the precision of mechanical watches by counterbalancing the disturbances in the isochronism of the resonator due to earth’s gravity. This mechanism was invented by French watchmaker Abraham-Louis Breguet in 1801.

This device is very complex to make, which is why it is fitted with very few mechanical watches. Blackout concept in the honor of being able to offer it now in its range.

It should be distinguished from the carousel with which it can be confused. The latter, invented in 1892 by B. Bonniksen, if it pursues the same objective and appears very similar, is based on a different mechanical arrangement. After much research (on the terms and concepts included in the tourbillon patent in particular) and discussions with a confrontation of points of view, we can agree, following the perspective of Joseph Flores that the fundamental criterion that signs a tourbillon is the presence a fixed cog on which the tourbillon cage engages. On the other hand, a carousel does not have this fixed wheel and its operation is rather based on the principle of a differential causing the carousel to rotate by meshing of two cogs producing a relative movement between them which differs. The criteria of rotational speed, as well as the position (central or eccentric) of the balance axis are now irrelevant to distinguish them.

Finally, if the initial Breguet patent included a cage held between two pivots (like a bicycle wheel), Alfred Helwig for his part designed around 1920 a variant making it possible to do without the second pivot (like a spinning top). To do this, the cage is fixed by a base which allows it to rotate while being held by this side only, which gives the impression of being not held when viewed from above and called the “fliegendes” Tourbillon. or flying tourbillon.

The Carbon forged

Forged composite is a type of carbon fiber SMC material composed of small pieces of carbon fiber composite material which are pressed into shape when the resin hardens. This contrasts with most carbon fiber composites, which are made up of larger continuous layers that are “laid” one at a time, often manually. Forged composite allows a wider range of shapes to be accurately formed compared to traditional carbon fiber. The forged composite contains a higher volume fiber content which, combined with a higher variation in strand orientation, increases the average strength and reduces variability compared to standard carbon fiber. third denser than metallic titanium but more resistant, and consists of carbon fiber cables sandwiched between two layers of film-coated resin. It uses about 500,000 intertwined fibers per square inch. The fibers contain interwoven and folded sheets of carbon atoms aligned with the length of the fiber, and the interlacing has improved the strength of the fiber. The result is improved load capacity measured in flexion per unit mass. Due to its chopped nature, it can be molded in much more complex geometries than traditional carbon fiber composites, and is suitable for fabricating three-dimensional parts and parts with intricate details such as thickness transitions, holes, compound curvature, etc.
Blackout concept uses forged carbon due to the unique appearance of the material. But also for its lightness, its resistance to shocks and scratches. The structure of the Pilot P03 series gearbox becomes practically indestructible.
Blackout concept to develop this model for nearly 3 years. The result is an excellent harmony between design and performance.

This week let’s discover the Swiss watches Blackout Concept. A brand whose links with the automobile are numerous, as you will see.

Blackout Concept was created in 2006 by Fabrice Letellier, a watchmaking enthusiast whose past is essentially automotive. After being a professional race driver, he ran an engine preparation company.

In the early 2000s, he appreciates customization and circulates in black matte cars with black rims … hence the idea of ??declining this concept in watchmaking!

Amazing activity for some, Blackout Concept realizes the customization of prestige watches. An activity carried out in Switzerland by Swiss watchmakers qualified and perfectly able to intervene on Rolex for example. This customized customization allows to create a unique watch, which can for example be made on a Rolex.

The brand also offers its own models since 2015, such as this Pilot P-01 Chrono Concept watch. A desire to create a range of quality and affordable quartz watches.

For this watch, BOC has selected a movement of the electromagnetic mecaquartz chronograph type from Miyota.

In other words, it is a hybrid movement between a mechanical watch and a quartz watch. Seiko had created the Spring Drive technology in 1998 with an electromagnetic regulator that guides a mechanical movement. The objective is to avoid any variation due to shocks or temperature variations, for example.

Designed and assembled in Geneva, this Blackout Concept watch is perfectly in the spirit of the company’s flagship customizations in terms of style.

In terms of presentation, the black stainless steel case has a retangular shape that does not go unnoticed. The matte black look continues on the easily adjustable rubber strap.

The sapphire crystal brings an appreciable solidity, for a watch usable daily without risking an unwelcome scratch. Water resistance to 100 meters, stopwatch, display of the day of the month,

On the back of the case, the number of the copy of this series limited to 300 pieces proves to us that we are dealing with a limited edition.

This Blackout Concept Pilot Watch P-01 Chrono Concept is available in several variants, no less than 6 variations that play on the colors. A box of 4 models Pilot is even proposed, for a price less than 3 watches.


Offer yourself a Swiss assembled watch at a bargain price and with a successful design: the promise of Blackout Concept is kept. The Pilot P-01 watch is attractive and pleasant to wear, and comes with a real originality.

Note that a Blackout Concept watch is guaranteed for two years, and is delivered in a beautiful box rigid, black and zipped with its certificate of guarantee.

Our thanks to Blackout Concept for the discovery of this Pilot watch, and to LTI Cars for the photo shoot with a Porsche 356.


316L steel / PVD

Blackout concept also chose this material.
Recognized for its many qualities, stainless steel is the one that best illustrates this evolution in the dressing of wristwatches.

It is interesting to note that luxury watch brands, accustomed to gold and platinum, quickly adopted it with a preference for 316L steel – also known as surgical steel.
Robust, non-allergenic and resistant to corrosion, it sometimes benefits from surface treatments that improve its qualities, such as PVD (Physical Vapor Deposition), DLC (Diamond Like Carbon) or BOC coating (DLC base) * on our customizations.

More efficient but rarer, the 904L steel, used by Rolex, is for example exploited in the space sector and the chemical industry. The manufactures size Oyster cases in massive Oystersteel steel blocks belonging to this family of super alloys.

* The black treatment B.O.C (Blackout concept) is a unique innovation created after several years of research thanks to the assistance of physical engineers in Geneva. They also managed to find the best possible ultrasound treatment, thanks to the chemistry NGL of Nyon (VD). The preparation before treatment is of great importance.
When the maximum results are achieved, our work can begin.

We will keep our development technology secret. In addition, we will surely remain for a long time the only company to offer a 10-year warranty on the BOC (Blackout concept) treatment. Our technique brings a result of incomparable brilliance and depth of black.
We are close to the ceramic keeping the shades of steel. Also know that the treatment B.O.C (Blackout concept) does not fear the scratchs.
B.O.C. Treatment = Quality, Resistance and Longevity
