The Ref. 2444 laid the design foundations for its successor, Heuer's famous Carrera line. Affectionately known as the "Pre-Carrera". This beauty is a three-register chronograph with three oversized sub-dials. Sized at 35 mm, the stainless steel stepped case is clean in its design. It features long lugs, and small round pump chronograph pushers. 

It is powered by the ever-reliable Valjoux 72 which was also used by the Rolex Daytona and later Heuer models.
