While it's certainly possible that it's true, this is a secondary source,
and it would be nice to see some confirmation from a source written in that
period. Did the author cite a source for the information? The British Royal Navy
had a similar number of chronometers by 1790 at the latest. Is it possible
that the French were forty years behind the British? Of course, France had
been through one emperor and two revolutions by this date, one destructive and
chaotic (1789) the other constitutional (1830), and its colonial ambitions
were focused a bit closer to home --on Algeria with only a little water to
cross. So perhaps it's true that they had so few chronometers in 1833. It would be
interesting to confirm it.
