A barometer and clock are very handy to have onboard. The barometer doesn't have to be accurate because you are looking for trends not actual pressure (unless you are landing helicopters onboard). Most will do the trick. I have an old fashioned anaroid which works well but you have to look at it every hour or so and write down the pressure to note trends. I also have a modern digital one which is great because it records the pressure and shows you the trend.
The clock is for looks only. Most watches are as good and the most accurate time onboard will be your GPS. In order to call your clock a chronograph you would have to start recording daily error and keep a log. I don't think anyone does that anymore. Most folks just get the correction from GPS or a time hack on HF whenever they need really precise time for astronomics.
There is a tide in the affairs of men,
Which, taken at the flood, leads on to fortune;
Omitted, all the voyage of their life
Is bound in shallows and in miseries.
