With the Aikon Master Grand Date, Maurice Lacroix gives life to a brand new movement and design. A newcomer to the company's line of manufacture movements, the ML331 calibre features a balance visible through a large skeleton aperture at 8 o'clock on the dial and a double date window, visible at 10 o'clock, integrated into the thickness of the calibre itself. The movement can also be glimpsed through the small seconds counter at 4 o'clock, as well as through the sapphire crystal-protected back. The hours and minutes are off-centred at 2 o'clock. The 45-millimetre case in polished and matt steel is topped by the knights on the bezel and is fitted with a Cordura strap that can easily be exchanged for a steel bracelet, supplied with the watch, thanks to the practical EasyChange system.
