Absolutely right.  As I said in an earlier post, any watch with that degree 
of accuracy can be regulated so as to keep perfect time, with a bit of trial 
and error.  BTW, I saw a very well made recent film depicting the incredible 
history of the development of the marine chronometer.  It is unforgettable.  
The name is "Longitude".
