Sinn 903 St BE II Navigation Chronograph Bracelet Watch 903.091 Bracelet

The Sinn 903 St BE II Navigation Chronograph Bracelet Watch 903.091 is a masterfully engineered pilot chronograph that combines decades of aviation heritage with cutting edge innovation. Designed for precision navigation, this Sinn watch features a highly functional slide rule bezel with logarithmic scale, enabling calculations such as fuel consumption, distance and speed directly from the wrist. The 41mm stainless steel case has been completely redesigned for enhanced durability and performance, while maintaining the iconic aesthetic that defines the 903 series.

At the heart of the watch is a high precision column wheel chronograph movement, delivering exceptional accuracy and a power reserve of at least 60 hours. The striking dark blue dial features a classic tri compax layout with three sub dials for chronograph functions, while hybrid ceramic luminous elements ensure outstanding visibility in low light conditions. Sapphire crystal with anti reflective coating provides superior clarity and protection, while water resistance up to 200 metres ensures versatility in demanding environments. Finished with a stainless steel bracelet, this navigation chronograph offers the perfect blend of technical excellence and timeless pilot watch design.
