With the
Twenty-8-Eight Tourbillon, first released in 2010, DeWitt took a major
step forward as the calibre DW8028 was its first entirely home-made
Tourbillon movement. A landmark in the history of the brand showcasing
yet again the depth of its know-how and its autonomy.
DW8028 - solid and reliable
The
DeWitt calibre DW8028 is a manually wound movement integrating a solid
and reliable Tourbillon mechanism. Its construction is rather classical,
using age-old and recognized technical parameters as a basis: 18’000
A/h, 72 hours power reserve. The movement is equipped with a Swiss
anchor escapement with a variable-inertia balance and a spiral with a
Breguet curve sequenced at 2.5 Hz.
The balance, as well as the escape wheel and the anchor are made of 18 carat yellow gold.
A signature plate for the master watchmaker
The
Twenty-8-Eight Tourbillon fully complies with the very demanding
finishing norms of the DeWitt Manufacture. Entirely hand-made, the
finishing is here of a rare quality and can be observed through the
sapphire crystal back. Meticulously angled, polished and satin-finished,
the barrel and cage-bridges are finely decorated with Côtes de Genève.
Also, two miniature “W” signatures are to be found on the crown and on
the golden buckle.
A little plate, bearing the signature of the
master watchmaker and placed on the barrel-bridge, further witnesses the
pride and affection put into the creation of each timepiece. A direct
connection is therefore established between the client and the
watchmaker behind his work of art. Indeed, one particularity of DeWitt,
so essential to the final quality achieved for the product, is that
every watch is entirely assembled, adjusted and tested by a single
master watchmaker, from A to Z.
Strength and Finesse – a design about duality
The
dial of the Twenty-8-Eight Tourbillon is all about duality! On the
upper part, a set of columns compose a very masculine and imposing Art
Deco construction with a futuristic touch. It also sends us the image of
the front of a powerful 1930’s steam engine. The lower part of the dial
opens up into a large and beautiful circle symbolizing wholeness, the
infinite nature of energy and... female power.
However large
the opening, the entrance into the heart of the beating movement is
protected by a semi-transparent grille that only intrigues us more on
what is happening inside.
The underlying pattern represented on
the dial is a large radiating sunray that reaches right out to the
sides. It is divided in two different colour zones as the Roman and
Arabic numerals are placed on a Rhodium or Palladium circular applique
that embraces the whole dial.
