The Sinn 903 St HB Navigation Chronograph 903.095 Limited Edition is a tremendous chronograph with the impeccable Sinn quality, design and finishing level. 

The watch has all the basics right, such as 200m water resistance, scratch-resistant sapphire glass with an AR coating, a very comfortable fine link bracelet with an additional leather strap and a solid LJP L110 mechanical (automatic) chronograph movement, which boasts 60 hours of power reserve, that is visible through the display caseback window. But it goes beyond that with DIN 8309 anti-magnetism, bezel with logarithmic scale and slide rule function and just a simply stunning vintage design.

This beautiful Limited Edition watch is limited to 500 pieces worldwide.
