POTTWATCH recalls the history of the Ruhr Valley and gives you the opportunity to share the love for your home with others. In the dark, a luminous effect illuminates the dial - as a miner's lamp once did the miner's way. The last hard coal from the Prosper-Haniel coal mine in Bottrop, refines the back of our timepieces. Every single watch is unique, individualized by the raw material that shaped the region so strongly. Made in Germany - assembled in Duisburg.
