The 17.09 is an evolved daily wearer with new, extra functionality and overall design updates. For the first time, we bring laser-etched, lume-filled sapphire to our entry level watch: the indices have now moved to the underside of the top crystal and glow with a new intensity. They reflect the graphic design language first shown on the 18.01 H41 and 27.01, and are complimented by a bold new handset derived from the 20.01 Chronographs.
