Hamilton embraces our passion for aviation and our insistence upon accuracy with the Khaki ETO (Estimated Time Over). With a turn of the bezel to mark appropriate speed, desired arrival time or journey duration, the ETO makes the calculations to help you plan your journey. Official ETO aviation regulations allow five minutes tolerance: Hamilton does not.
