Sinn 903 St II Navigation Vintage Leather Watch 903.090 Vintage Black Leather

The Sinn 903 St II Navigation Vintage Leather Watch 903.090 is a highly sophisticated pilot chronograph designed for precision navigation and advanced functionality. With decades of heritage behind its design, this Sinn watch features a 41mm stainless steel case and an iconic slide rule bezel with logarithmic scale, allowing the wearer to perform calculations such as fuel consumption, distance and speed directly from the wrist. This makes it an indispensable tool for aviation professionals and enthusiasts alike.

Powered by a high quality column wheel chronograph movement, the watch delivers exceptional accuracy along with a power reserve of at least 60 hours. The classic tri compax dial layout includes chronograph counters for 12 hours, 30 minutes and continuous seconds, while luminous hybrid ceramic elements ensure outstanding readability in low light conditions. Sapphire crystal glass with anti reflective coating provides durability and clarity, while water resistance up to 200 metres enhances versatility. Finished with a vintage black leather strap, this watch combines technical mastery with timeless pilot watch design.
