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.
