Important Clocks and
Scientific Instruments from
the Collection of the late
Professor E.T.Hall C.B.E
Professor Hall purchaced this clock at the
NAWCC national convention in 1996,
where he was lecturing on his super precision high vacuum pendulum
regulator.
This is a side view of the fully jeweled movement
This was the first of the Munro regulators to feature the extremely thin steel 'scape wheel, with synthetic ruby pallets.
This is a view of the silvered astronomical dial with sunken subsidiaries, and blue steel hands
This was an early use of my massive brass risers in a half seconds pendulum.
I'd like to hear from you if you were the purchacer of this clock!
