The Sinn 903 St II B E is a 41 mm automatic navigation chronograph, instantly recognizable by its deep blue dial paired with silver subdials and ivory-colored luminescent elements.
Its integrated rotating bezel with logarithmic scale makes the 903 a true calculating instrument on the wrist, used notably to work out times, distances or fuel consumption. The indices, the 12 numeral and the hour and minute hands incorporate luminescent hybrid ceramic elements, ensuring outstanding legibility in the dark.
The 903 St II B E is powered by the LJP L110 automatic caliber, a column-wheel chronograph movement with a power reserve of at least 60 hours. Visible through the sapphire crystal caseback, it completes a technical construction featuring Sinn DSP technology and water resistance to 20 bar.

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.
