====== Sinn 103 Ti Ar ====== {{wst>image_cr|Sinn|103 Ti Ar}} {{wst>image_cr|Sinn|103 Ti Ar UTC}} *Main Article [[Sinn 103]] The **103 Ti Ar** (**103 Ti Ar UTC**) is a [[pilot's chronograph]] by [[Sinn]]. The **103 Series** has been a classic in the ranks of high quality and functional chronographs. Whether with acrylic or [[sapphire crystal]] glass, from [[titanium]] or stainless steel, it fulfilled almost all the wishes and demands of professional use as a pilot's watch, but only almost all requirements. With the **103 Ti Ar UTC** a last gap in the model family is closed. The 103 UTC is based on the [[ETA]] movement [[Valjoux 7750]] with a [[second timezone]] especially interesting for pilots and frequent flyers. The case of this model is made of pure [[titanium]] and equipped with the argon technique developed by Sinn. The pilot's bezel, also made of pure titanium, was partially anodized black for a better readability. The classic [[dial train]] of the 103 UTC has been supplemented by a bright yellow hours hand for the [[second timezone]]. The glass bottom allows free insight into the complex mechanics of the Valjoux 7750. The 103 UTC is available with the classic leather strap or a solid pure titanium band. The 103 Ti Ar won the [[Goldene Unruh]] award in [[1998]].
