Here is an incredible opportunity to own a watch from the personal collection of Helmut Sinn!  Offered here is Mr. Sinn's personal Model 142, the iconic chronograph designed for the Spacelab missions.  Powered by the Lemania 5100, this chronograph features Day/Date displays, three sub dials and an internal rotating bezel (operated from the crown at 10 o'clock).  In absolutely beautiful shape inside and out, this impressive timepiece comes with documentation of Mr. Sinn's ownership.  Pictured on his website, HERE.
