subject: Graham Swordfish Chronograph Iris [print this page] This must have been about the idea that crossed my mind to research and development department of London Graham when he
conceived Swordfish Iris the new watch inspired by the Maison dall'orologiaio English George Graham (1673-1751) led, playing
at home, at SalonQP 2011 .
Do you know what Iris? Rainbow. Its colors - so-called iridescent and indefinable - are a mix of iridescent hues, just like
the Swordfish Chronograph Iris. These effects were created during the machining of steel box: all the details that compose
it, are put under vacuum. The unique coating which subsequently form, caused by a reaction to the plasma consists of a
multilayer structure characterized by colors that change with the reflections of light.
Graham Silverstone Tourbillograph Full Black
The Silverstone Tourbillograph Full Black is a self-winding chronograph with column wheel and tourbillon. This is an
automatic movement with tourbillon perfectly developed to trace the DNA of the last Graham timepiece, the design is very
powerful and combined with rich content technology. The domed sapphire crystal is of extraordinary size (42 mm in diameter)
and provides a view of some details of the mechanism. The 48 members of his cage skeleton are intertwined with each other and
the total weight of the mechanism is reduced to only 0.485 grams. This building, called the tourbillon Cintr integrates into
the chronograph complication despite the use of a large diameter wheel.
The Calibre Graham built exclusively for the manufacture La Joux-Perret has come to light after four years of research and
two patents. Overall, the engineering know-how has acted by abolishing the intrinsic weaknesses of the tourbillon. First of
its fragility. The reduced number of elements, lightness, and the double-deck provides stability and rigidity to the
building. In Graham's call it "Tourbillon impact resistant." To reduce the sensitivity of the device controller to the
magnetics in the cage was made extensive use of special iron-free. Its exhaust vibrates at 28,800 vibrations / hour.
Graham pointed out that in the end result is to offer a friendly and aesthetics as the tourbillon complication with the
resistance of a military watch. The Tourbillograph Full Black has indeed passed the test Chronofiable , reference test
established in animals 70 Swiss watch industry for a period of 21 days, equal to six months of actual use.
Aesthetically, the Silverstone Tourbillograph Full Black has an exclusive sports. The thin steel case measuring 48 mm and is
well-titanium carbide with black PVD coating, such as its bezel. The dial, also black, has a shiny appearance due to rhodium,
the Arabic numerals are visible or blurred, playing a tone on tone effect.
The finishes of the caliber that La Joux-Perret has accustomed us are of Haute Horlogerie: even the smallest mechanical part
was rhodium. The rotor is supported on bearings and ceramic column wheel that controls the chronograph displays elements
