Maurice Lacroix Masterpiece Square Wheel “Pink Pearl” Limited Edition

The Masterpiece Square Wheel (formerly the Masterpiece Roue Carrée) is the only watch in the world to feature a functional square wheel mechanism. Maurice Lacroix now enhances this collection with a new model, the Masterpiece Square Wheel “Pink Pearl”, a sparkling feminine timepiece dedicated to beautiful wrists.

The Masterpiece Square Wheel “Pink Pearl is a beautiful timepiece which commands attention with each facet of its form – Shimmering pink mother-of-pearl dial, sparkling diamond set case and pink large-scale crocodile-skin strap with a pearl effect finish.

The stainless steel case, measuring 43mm in diameter, provides the ideal size for the depiction of time, ensuring ease of readability. The Masterpiece Square Wheel “Pink Pearl” features diamond-cut Hours and Minutes hands which illuminate in poor light with a white glow. They convey time with traditional elegance and grace. The printed indexes for the hours and minutes are accentuated with glistening diamonds.

A power-reserve indicator is located adjacent to the crown, showing the status of the mainspring against a printed series of indexes.

The allure of the Masterpiece Square Wheel has always been the interaction between a clover-shaped and square wheel. The “Pink Pearl” continues to mesmerise with its innovative seconds display. The open-worked square wheel with a luminous tip at its centre captivates eyes.

Two overlapping recessed areas provide demarcation for the clover-shaped and square wheels. The grey surface is actually an exposed area of the movement bridge, effectively the chassis of the movement within. It reminds the wearer that inside the “Pink Pearl” resides much beauty.

A large sapphire-crystal caseback reveals the sophistication of the Maurice Lacroix automatic manufacture Calibre ML 156, the 10th manufacture movement created by Maurice Lacroix. It is presented with Grand Colimaçon decoration, features 249 movement components, a swan-neck regulator and screwed balance.

This impressive specification stands testament to the exemplary craftsmanship practised by Maurice Lacroix in its desire to meet the demands of the most discerning clientele.
