Introduced at Baselworld in 2007, Sinn designed the 757 to be a "super" tool watch with a pilot's watch bezel. The company refers to this range as Instrument Watch and this model (along with the related Sinn 756) as "Duochronograph". No model in this range includes the small seconds subdial typically seen on a Valjoux 7750 watch, though the typical chronograph registers are retained at 6:00 and 12:00.
Duochronograph by Sinn with automatic winding, tegimented stainless steel case with dehumidifying technology, captive, tegimented stainless steel turning bezel with minute ratcheting and UV-resistant matte black dial.
This watch combines a whole range of advanced technologies. And according to a Chronos report (Special Issue 2/2007) it comes at a sensational price-performance ratio: For other manufacturers a watch with these properties would cost many times more.
From the beginning, a UTC option was also offered on the model 757. An extra hour hand, independently adjustable, is added. As of 2008, Sinn began offering its DIAPAL oil-free escapement technology on some 756 and 757 models. These also add a UTC independently-adjustable hour hand. In 2009, a blacked out "S" model was also offered.
