The Hamilton 992B Railroad Special can serve as a cost effective mechanical marine chronometer for celestial navigation if kept horizontal at constant temperature. See link:
1970 was the last year of production so if a sailor trys to use one for CN then it should be serviced by a professional (good for five years) then rated in the position as secured onboard before a journey/race. This would be a cost saving choice to consider as a small craft racer in the 2018 Golden Globe Race.
