Stopwatch for Astro Nav

[Bilgediver]

Thanks for the replies, much appreciated.

I have a cheap'n'cheerful £10 waterproof Casio that lives on the binnacle with the hour beep set to remind us to update the log on passage. If I were to synchronise that to the Greenwich time signal (Radio 2 or 4) when in the UK, then log the time changes observed per day over a period of days after setting, perhaps this could be the 'chronometer'?

I have to say, I like the idea of removing any steps in the calculation - the numbers just swim around at the mo!

I have read that there are time signals available on VHF so that you can sychronise watches anywhere in the world but can't seem to find any way of receiving them - does anyone have any ideas here?

Cheers,
Pete

The time signals are on short wave but you need to reed up about them to make sense of the gaps etc in the rythym of the beeps to understand what they are saying.
