Watch The Navigation Chronograph 903 St II G

The Watch

The watch presented here is a high-precision timepiece crafted in Germany. Designed for men, it embodies a sophisticated yet robust aesthetic thanks to its 316L stainless steel case. This material delivers outstanding corrosion resistance and ensures the timepiece stands the test of time. With a diameter of 41 mm and a thickness of 14.5 mm, it commands a strong wrist presence while remaining comfortable to wear. Its round shape combined with matte and polished finishes adds a modern, elegant touch, while the domed sapphire crystal with double anti-reflective treatment guarantees perfect legibility in any conditions.

The Dial

The dial is undeniably the visual centerpiece of this Sinn watch. Its rich green hue, enhanced by a sunray finish, captures light exquisitely - producing subtle, dynamic reflections that shift with every movement. Dark Arabic numerals meet hand-applied indices, all coated with a hybrid ceramic luminescent material for effortless readability in low-light conditions. A discreet data window is elegantly placed on the dial. The tricompax layout offers a clean, intuitive arrangement of the three galvanized silver sub-dials dedicated to the chronograph - a functional addition that blends seamlessly with the overall aesthetic.

The Movement

The engine of this impressive watch is its Swiss automatic La Joux Perret LJP L110 movement. This precise caliber embodies Swiss watchmaking excellence, beating at a frequency of 28,800 vph (4 Hz) for accurate timekeeping. The column wheel mechanism adds an extra layer of complexity and delivers an incomparably smooth operation. With a power reserve of 60 hours, this movement offers generous autonomy for those who love rotating between pieces. Chronograph functions include a chronograph with a stop-seconds device, synchronized for the display of hours, minutes, seconds, and dates. An integrated magnetic shield also protects the movement from magnetic fields, preserving long-term precision.

The Strap

The strap on this watch is crafted from brown calfskin leather, blending luxury with everyday functionality. Quality contrast stitching highlights its elegant profile and durability for both daily wear and special occasions. The 22 mm lug width ensures a balanced proportion with the watch case. It fastens with a silver pin buckle. You also have the option of a stainless steel bracelet, available via the dropdown menu, secured with a deployant clasp. The polished and satin steel finishes contrast beautifully with the elegance of this watch.

Water Resistance

The water resistance of this timepiece is exceptional, certified to 20 ATM (200 meters). This makes the watch an ideal companion for swimming, diving, and watersports where ruggedness and water resistance are non-negotiable. A screw-down crown and screw-down caseback together ensure the internal components stay fully protected from water intrusion.
