A true innovator came from that region of Britain but was forgotten for a few centuries until his flight surfaced a few decades ago, his name was John Harrison -


"The application of a Timekeeper to this discovery is founded upon the
following principles: the earth's surface is divided into 360 equal
parts (by imaginary lines drawn from North to South) which are called
Degrees of Longitude; and its daily revolution Eastward round its own
axis is performed in 24 hours; consequently in that period, each of
those imaginary lines or degrees, becomes successively opposite to the
Sun (which makes the noon or precise middle of the day at each of
those degrees and it must follow, that from the time any one of
those lines passes the Sun, till the next passes, must be just four
minutes, for 24 hours being divided by 360 will give that quantity; so
that for every degree of Longitude we sail Westward, it will be noon
with us four minutes the later, and for every degree Eastward four
minutes the sooner, and so on in proportion for any greater or less
quantity. Now, the exact time of the day at the place where we are,
can be ascertained by well known and easy observations of the Sun if
visible for a few minutes at any time from his being ten degrees high
until within an hour of noon, or from an hour after noon until he is
only 10 degrees high in the afternoon; if therefore, at any time when
such observation is made, a Timekeeper tells us at the same moment
what o'clock it is at the place we sailed from, our Longitude is
clearly discovered." John Harrison

The 24 hour system and the Lat/Long system fits inside the 1461 day system which in turn is derived from a specific set of references using the annual motion of the Earth. Harrison did not need to know the dynamics behind the inequality in natural noon nor the framework which gauges orbital cycles using full rotations within the confines of 4 annual circuits, he did however take into account the necessity of the February 29th leap day by assigning an Equation of Time value for that day.

It is utterly despicable on the part of contemporaries that they cannot stitch together the two parts of timekeeping into a continuous narrative even though that narrative has been offered many time and supported by so much historical and technical evidence.

Harrison's treatment at the hands of academics makes awful reading but that is not possible nowadays when readers can easily pick up where that narrative left off and simply enjoy the principles without having to wait for the academics to catch up nor wait for a sanction that isn't going to come.

Not true. He was a legendary clock maker and his clocks are kept and
revered in national museums. They presently reside at Greenwich. I know
a local master clockmaker who has been commissioned to make a replica
for another museum fairly recently.

His tomb was even restored by the Worshipful Order of Clockmakers in
1879 despite the fact that he never bothered to join them. He was held
in that high esteem. There is a blue plaque on his last house in London.

Mainly he had bother with the longitude commission about getting paid
when it was obvious to everyone except the new Astronomer Royal,
Neville Maskelyne that he had clearly won the competition. Eventually he
appealed over their heads directly to George III and they paid up.

The modern Chronophage clock in Cambridge deigned by the cordless kettle
magnate John Taylor also has a grasshopper escapement (a Harrison
invention).

I understand there is another in the works or awaiting shipment to China
that will feature a dragon shaped grasshopper escapement.

You come from a cult which still tries to subvert the principles which tie the 24 hour system to daily rotation via the Lat/Long system by trying to alter the references to circumpolar motion -

http://hypertextbook.com/facts/1999/JennyChen.shtml

The system of references on which Harrison's work is based originates in the most inviolate proportion is all astronomy linking the number of days with 4 years and its dynamical equivalent of the number of rotations within the confines of 4 annual circuits.

Harrison could check the accuracy of his watch using any foreground reference and the daily return of a star however that is only accomplished within the calendar framework which departs from the annual cycle of 365 1/4 rotations per circuit and formats observations into the familiar calendar framework of 365/366 rotations. Shame you can't understand the importance of the distinction between pure planetary dynamics and the timekeeping format but unfortunately haven't seen anyone who can manage to correlate even the 24 hour day with a single rotation nor its extension of 365 1/4 rotations per orbital circuit.

Like the worthless wandering Sun analemma, using a watch and stellar circumpolar motion is equally worthless for extrapolating the daily and annual motions of the Earth.
