Sinn Rallye Chronograph Model Series 917

Sinn presents the 917 rallye chronograph Collection dedicated to Rallye racing which requires extreme precision and reliable functionality. 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.

All in all, this new watch is perfectly suited for use in road rallies as well as any other situation.
