Talk about RARE, this is the original piece from URWERK. Felix and Martin had a dream of the brand they wanted to create, but no resources. These pieces were made without the use of CNC and the sale of them funded the company. It was made in Stainless Steel because they could not afford gold for the cases. This is why the 102 was actually made BEFORE the 101.

Note that the watch currently for sale has the black time display (not the silver in some pics and videos). It has the very rare original box and papers and is on an aftermarket strap.
