The length of day on Mars is very close to that of Earth. I would propose a Mars second as 1.027 Earth seconds. A Mars watch could be made out of an Earth watch just by slowing a hair. Earth latitude and longitude could be used on Mars by using a nautical mile of .5324 of the Earth nautical mile (close to a kilometer).
