Maurice Lacroix Watch Aikon Chronograph AI1018-PVB21-330-1. AIKON is the descendant of the Maurice Lacroix Calypso. This steel watch was one of the brands iconic models in the 1990s and bore the same design codes that live on in the AIKON. The integrated and water resistant case, the six arm bezel surrounding a flat sapphire crystal and the strap marked with an applied M logo made this model with its exceptional presence the brands most iconic product.
