I have an older GE table clock on the nightstand. It makes zero noise and keeps excellent time. Another benefit is that it has no alarm, a superfluous accessory for a retired guy.
FWIW, I've used those ship's clocks, mainly for shooting location with a sextant. Accuracy was kept by tuning the radio in the wheelhouse to the Denver broadcast of universal time with a count down to the hour and second, adjusting the clock accordingly. A couple of seconds of inaccuracy would put your location 100 miles off, East or West. I have no clue how they did it before radio, accuracy was probably not an issue.
