Maurice Lacroix Masterpiece Gravity

Maurice Lacroix Masterpiece Gravity is the first timepiece to feature a fully silicium assortment. Developed in-house by this inventive watch brand, it is the latest example of the company’s forward thinking approach to watchmaking.

The Maurice Lacroix Masterpiece Gravity utilises the very latest cutting-edge technology, silicium. Maurice Lacroix’s Head of Movement Construction, Michel Vermot, in collaboration with Haute Ecole Arc, based in Le Locle, was the first person to develop and produce a complete assortment made in silicium.  The silicium assortment includes the double roller of the balance, the pallets and the escapement wheel.  Silicium, a self-lubricating, glass-like material, is three times lighter than steel.  The low mass consumes less energy, is more accurate and does not require regular lubrication.

The frequency of the Maurice Lacroix automatic manufacture Calibre ML230 is 18,000 vph (2.5Hz). It is a cadence that is ideally suited for silicium as it proves gentler to the glass-like substance than those experienced in some higher oscillating movements.

The brand has minimised the number of components to 188, avoiding unnecessary parts and, by default, providing a clean appearance and enhanced reliability. The Calibre ML230 is its 13th manufacture movement, reaffirming the company’s know-how and technical progress.

The Masterpiece Gravity is available in a Classical model, presented in a stainless steel case, and a Contemporary model, delivered in a sultry anthracite PVD finish. The diameter of 43mm bestows a generously sized area on which to display the various design components of the watch.

A key element of the Masterpiece Gravity is the “glass-box” sapphire crystal which is domed and magnifies the oscillator and assortment making them appear to sit high within the case and according a sublime three dimensional characteristic. An off-centre Hours and Minutes display features a white lacquered dial which is domed at its centre and retained with two mirror-polished screws. It includes diamond cut indexes on the Contemporary model and Roman numerals on the Classical model. Framing the extremities of the dial is a flat minute rail, featuring circular brushing.


Hours and Minutes hands are thermally blued or rhodium plated dependent on the model selected. A small seconds display partially projects over the disclosed balance assortment, masterfully exploiting depth and curving line.Adjacent the functions presented is a delightfully decorated canvas of Clou de Paris or Grand colimaçon. Again, dependent on the model chosen, this is rhodium or black gold treated.


The watch has an exhibition caseback, affording a view of the delightfully decorated self-winding movement, featuring Grand Colimaçon shaped Côtes de Genève motif. The generous proportions of the movement indulge the eyes with a large-scale view of each finely finished surface.
