I’m sure that same bridge crew winds the chronometer in the drawer of the chart table every day at exactly the same time and then notes any error, the successive daily rate, with average daily rate.
When in danger
OR in doubt
Hoist all sail
and you know the rest.
They damn well better. On a carrier, there is more than one. I know there are at least two on the bridge, one on the flag deck and another in secondary conning.
Well yes and no, at least in the Navy. The chronometers are still compared every day and the rates noted but the old wind-up chronometers have long since given way to battery-powered quartz chronometers. I however, like any good QM, still have my chronometer key (7 1/2 half turns).
