IWC Schaffhausen Ingenieur Chronograph and Ingenieur Chronograph AMG (2005)

In 2005, IWC added two new Ingenieur Chronographs to the  Ingenieur Automatics line: One is the classic, rather purist variation in a stainless steel case and the second watch in the Edition Mercedes-AMG has a titanium case.IWC Schaffhausen Ingenieur Chronograph and Ingenieur Chronograph AMG (2005)The inner workings of both timepieces are the same. And on the outside they are definitely the siblings of their respective Ingenieur Automatic models. Even the dimensions are the same: 42.5 mm diameter. In brief: Automatic chronograph movement cal. 79350, small seconds with stop function, chronograph with 30-minute counter. In addition to the division for seconds and eighths of a second that this mechanical movement can offer with its 4 Hz, the dial has an external tachymeter scale for precise determination of speed over a measured distance. This is a ‘must’, not only but especially for the AMG Chronograph.

Otherwise, pure purism, but only of the highest level. What is true for the Ingenieur Automatic movement, is also true for the Chronograph movement: A case that is strong as a safe is good, and a shield against extreme magnetic fields is better. This meant that the chronographs also had to grow in height in order to accommodate the soft-iron inner case.

What’s more, the Ingenieur Chronographs rise above the army of watches with stop functions because of a critical detail: the operation buttons of the chronograph are harmoniously and functionally integrated into the case. These buttons with their high operational security strike a historical note to another watch, the Ingenieur with chronograph and alarm that was built from 1991.

That watch also had the integrated chronograph buttons. But it, like the graceful women’s Ingenieur from 1988, had the quartz hybrid movement calibre 633, and the women’s model without alarm function the calibre 631.
