The acclaim of the public and connoisseurs reserved for the now famous square wheel has led the rangeto be extended towards a level of ultimate refinement. In 2010, Maurice Lacroix revolutionized the mechanics of time by designing a square gear wheel, a first in watchmaking history which, beyond its aesthetic value, inaugurated a new way of charting the onward march of time. In 2011, the Maurice Lacroix square wheel offered new angle on time's course with its focus on the seconds hand. This year,the Masterpiece Roue Carre Seconde has been adorned with pink gold in order to highlight theexclusivity of its display mechanism. Designed by engineer watchmaker Michel Vermot in collaboration with the Haute Ecole Arc du Locle, the square wheel mechanism took years of development. By definition, the gears of the non-circular gearwheels cannot be regular. The principal challenge was therefore to determine the shape of their teeth, inorder to guarantee constant power transmission. The wheels were made using LiGA technology, arevolutionary process combining the techniques of photolithography and electro forming to produce micro components of high precision and finesse, unmatched by traditional machining methods.
