From product description:
With custom 3D printed watchbands made just for you and paired with your favorite Zub 40 timepiece, the NOOKA limited edition collection is one of the first hybrid accessories lines to pair the freedom of creation of 3D printing with high quality fashion.
This special edition has been made using technology of the future; 3D printed bands are fused into shape by a high powered laser, one layer at a time. Each band is created from an individually unique file and dyed in a small batch, using high quality fabric dyes. Over time you may see some wear in the color of your band, just like your favourite pair of jeans.
