The Sinn 903 St II G is a 41 mm automatic navigation chronograph that combines the iconic technical sophistication of the 903 series with a galvanized green dial enhanced by an elegant sunburst finish.
Its integrated rotating bezel with logarithmic scale allows various calculations, including time, distance and conversions. The tricompax layout of the silver sub-dials structures the dial, while the numeral 12, indexes and hands in luminous hybrid ceramic ensure excellent legibility in the dark.
The 903 St II G is powered by the LJP L110 automatic caliber, a column-wheel chronograph movement offering a power reserve of at least 60 hours. Its Sinn DSP technology allows the directly operated rotating bezel to remain water-resistant to 20 bar, completing a chronograph that combines functionality, precision and refinement.

What is a quick-release spring bar, and how does it work?
The spring bar is the small spring-loaded pin that connects the strap to the watch lugs. On a quick-release spring bar, a small lever protrudes from beneath the strap. Pull it with your fingernail and the pin retracts, releasing the strap.
Change your strap in four steps
- Pull the quick-release lever to release one side of the strap, then the other.
- Insert one end of the new strap’s spring bar into the lug hole.
- Pull the lever, align the other end with the second hole, then let go.
- Gently tug on the strap: you’ll hear a slight click, and it’s in place.
A strap for every occasion
Calfskin for the weekend, cordovan for work, alligator for special occasions: your watch can change its look as quickly as you do. One watch, several straps, and just as many personalities.
Select the quick-release spring bar option on the product page for each strap when adding it to your cart.
