Two years ago, Maurice Lacroix launched its technological breakthrough, an exceptional timepiece with the world’s first square-wheel mechanism. With the name that suits to its character, the first Masterpiece watch had required several years of development before it demonstrated a totally new way of displaying time. This year, Maurice Lacroix presents a Masterpiece Roue Carrée Seconde Or Rose timepiece that comes with a new breathtaking design.
Created in the Limited Series of 88 pieces, Masterpiece Roue Carrée Seconde Or Rose will be officially presented at the Baselword 2012 watch and jewelry show. Unique by its striking elegance and luxury, this extraordinary watch is made of pink gold that surrounds a beautiful dark brown, almost black movement plate which is used as a watch dial. However, the central part of the watch is still the amazing, rhodium-plated and pink gold two-tone version square wheel that indicates seconds at the 6 o’clock position. It is driven by a toothed, cloverleaf-shaped wheel, as accurate as the traditional round wheels do. Besides, their hypnotizing movements offer a great visual spectacle for the wearer.
An engineer, Michel Vermot, the head of the development department at Maurice Lacroix, and its team from the Swiss Higher Education Institution, the Haute Ecole Arc, are responsible for this great technological achievement. In order to overcome problems that come with irregular gear profile of non-circular wheels and to get the constant transmission of energy, they used a silicon-machining technology to craft very accurate, light and self-lubricating micro-components.
The final result was the creation of a ML 156 hand-winding movement, with patented square and cloverleaf-shaped wheels. Manufactured and assembled by Maurice Lacroix, this rhodium-plated movement, decorated with a Grand Colimaçon design, oscillates at the frequency of 18,000 vibrations per hour (2.5 Hz) and provides the power-reserve of 45 hours.
Besides wheels, the dark brown dial also incorporates a luminescent seconds pointer at the 6 o’clock position, activated by a clover-leaf wheel at the 9 o’clock position. The power-reserve indicator takes the 3 o’clock position. Polished pink gold hours, minutes and power reserve hands are attached directly to the main plate.
The pink gold case is nicely executed with polished and satin-brushed finishes and it has the masculine diameter of 43 mm. A screw-down case-back is covered with a large sapphire crystal with an anti-reflective coating. Maurice Lacroix Masterpiece Roue Carrée Seconde Or Rose watch is available with a large-scaled brown crocodile strap with black calfskin lining and a pink gold buckle.
