Khaki Aviation Chrono Quartz Quartz | 44mm | H76712151 This item is being sold as junk because it is not working. I think it is in relatively good condition. There are some minor scratches. The clasp is broken. I don't know if it can be repaired. This sporty quartz chronograph with a 44mm stainless steel case commemorates Hamilton, the official timekeeper of the Red Bull Air Race 2018. It's a perfect fusion of aviation style and Swiss precision.
