Manufactured in the Louis XVI style, both clock and barometer are encased within an ormolu case and flanked on either side by trumpet wielding cherubs, each surmounted with a patinated bronze sphere that is topped with a crown, the bases terminating in a pine cone finial.

The barometer face signed 'E. Mottheau Paris', the clock movement signed 'LEMERLE CHARPENTIER' and 'LESIEUR'.
