Nivada Grenchen has announced a new collaboration with the retailer Chronofactum to release the Super Antarctic Chrysokoll. This special edition watch features a dial crafted from Chrysocolla, a distinct green and blue gemstone. Due to the natural variations in the stone, each dial in this series offers a unique pattern, ensuring no two watches are exactly alike. The release continues the lineage of the Super Antarctic collection, a staple in the Nivada Grenchen catalog. This specific partnership highlights the brand's ongoing strategy of collaborating with specialty retailers to create unique material variations of their historical designs. The announcement directs customers to the Chronofactum website for purchase details and availability.
