The model J861/9, in Black and green color, black and green and white indices, offers perfect readability thanks to its sapphire crystal.
The choice of a sapphire crystal ensures exceptional visibility of the watch and gives it tremendous resistance to scratches. Due to its characteristics, sapphire crystal is exceptionally hard. Only diamond offers greater hardness than this material and is the material of choice for pieces that withstand the test of time while maintaining their beauty and good presence. Moreover, the crystal on this watch includes an anti-reflective treatment, greatly preventing the occurrence of uncomfortable reflections that hinder the correct reading of the dial under certain lighting conditions.
