Wouldn't it be beautiful to watch the glittering dark sky over the most beautiful and characteristic mountains of our country (Slovakia) at every look on your wrist? The snow-covered Kriváň, as the dominant mountain of the High Tatras, over which the endless night sky stretches, was our inspiration for the creation of this exceptional limited edition pieces from which we produced only 150 pieces. The authenticity of the dark sky is ensured by a dial made of genuine Aventurine stone. Because this stone is really fragile at the thickness of the dial used and can easily crack, there are only a few factories in the world that can apply (not glue) indexes with legs to it. In practice, this means that 24 small holes for the hour indices plus one larger hole for the hands need to be drilled in one dial. Thus, the completion of one perfect dial is preceded by six or more dials that cracked or were otherwise damaged during production. Each dial is unique in its structure, as is this exceptional limited edition.
