For the Master Square collection, Franck Muller designers once again drew their inspiration from Art Deco. The geometric purity of its lines ensures that the appearance of this model is perfectly harmonious and symmetrical. As its name indicates, the Master Square is square in shape with rounded angles that marry perfectly with the wrist. It is available in an infinite number of options thanks to its different case sizes, colour dials and Arabic or Roman numerals enhanced with a mirror or relief appearance. There is also a fine jewellery version with white or black diamonds. Harmony and balance are the watchwords when it comes to describing the design of the Master Square.
