Five hours on the road. Now ready for the next special stage after successfully mastering the winding mountain pass. A rally is all about maximum precision and functionality. This is where the 917 GR Rally Chronograph really excels: with a countdown rotating bezel that enables to-the-second target times to be easily read and accurately set, eye-catching red numerals for the last 15 seconds in the critical time zone, and an overview of all-important information at a glance on the classic dial under the anti-reflective sapphire crystal glass.
Thanks to the power reserve indicator, designed in the form of a fuel gauge, you can rest assured that your rally chronograph will go all the way to the finishing line and beyond. The sophisticated technical features of this timepiece guarantee the robustness of a high-end mechanical watch: model 917 GR is waterprrof, pressure-resistant up to 10 bar and resistant to low pressure, with Ar-Dehumidifying Technology to help slow down the ageing process of lubricants in the movement and prevent the crystal from fogging due to sudden cold. A top qualifier for both rallies and everyday wear.
