TRACKMASTER CHROMIUMThe pioneering automatic column-wheel Chronograph-Tourbillon has been imagined to pay tribute to the brands' passion for dynamism, performance and boldness. This exceptional timepiece features a very unique and innovative Tourbillon specifically engineered for a “sports” chronograph function-watch assembled on a “tyre effect” strap.The Trackmaster Chromium has been developed in the vein of Graham- London's “high adrenaline” timepieces leading to the creation of a new concept of Tourbillon, a new technology, a new manufacturing process and two new patents. As mechanical art explorers and craftsmen, four years of unremitting endeavours were necessary to the development of such a masterpiece.Powered by a column-wheel (black PVD coated) chronograph movement ensuring greatly enhanced precision, known as R.A.C or “roue à colonne”, this particular time instrument features a unique see-through case construction which allows a fascinating look through the refined mechanism of the “one minute” Tourbillon.The off-centre construction of the Tourbillon has the advantage of being lighter and therefore more reliable with a better resistance to shocks. The cage only weighs 0.485 grams and is made of 48 pieces. The high degree of precision is reinforced with the unique “Coq” and upper bridge construction which are shaped in the tradition of English high precision timepieces reminiscent of the 18th century. The high frequency of the balance wheel is 28'800 alternations per hour. It permits an easier adjustment and a more precise running.In addition, the double bridge construction, coated with black PVD, on both sides, front and back, a classical “à la Breguet” is clearly more reliable than a “Tourbillon Volant”. The reinforced Incabloc anti-shock system, including spiral, balance, escapement wheels and anchor, guarantees an excellent shock resistance that is vital for a “sports” Tourbillon with Chronograph function.Made for sports' and watch making passionate, the Trackmaster Chromium features exclusive material and decoration such as “Clous de Paris” on the case, silver galvanic dial, a large oscillating weight made of black Chromium and a silver segment and an integrated rubber strap which create dynamism and a perfect symbiosis between the technology and the look.
