Chronograph Watch - Model 917

The rallye chronograph
You’ve been on the road for five hours now. You’ve mastered the mountain pass with its hairpin turns, and are now ready for the next time trial.
Rallye racing requires extreme precision and reliable functionality. And that’s exactly what the 917 rallye chronograph delivers. For example with the easy-to-set countdown bezel that makes it possible to read off finish times with to-the-second accuracy.

With red numerals to call added attention to the all-important, final 15 seconds. The traditionally styled dial and non-reflective sapphire crystal glass make it easy to read all important information at a glance. And thanks to the
power reserve indicator (917 GR model), designed to resemble a fuel gauge, you can be sure that your chronograph is 100% reliable. In addition to technological sophistication, both models offer the robust reliability of a mechanical watch: shockproof and anti-magnetic, with a solid stainless steel case and the freedom from fogging that only the special Ar ®- dehumidifying technology from SINN can ensure. All in all, this new watch is perfectly suited for use in road rallies as well as any other situation.
