Model '''757''' is a [[chronograph]] by [[Sinn]] produced from [[2007]] to present.

==Overview==
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 [[Sinn Instrument Watch|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.

The [[Sinn 756]] is a similar model with a smaller case and plain [[bezel]].
