Here are the photos

is the first time that the justly famous Janvier clock has been
recreated.
Features;
The Double Pendulum Table
Clock has two independent trains and escapements each with its own
half second pendulum, the clock sits on a mahogany base edged with ebony
and has a brass and glass cover with an opening front door. The blue steel hand
and the gilt hour hand indicate local time from train and Pendulum 1, while
the gilt minute hand is set to indicate time at your home meridian from
train and Pendulum 2.
Two gridiron
pendulums each with Janvier style bobs suspended above the movement
on the brass arch
Two separate trains each
has its own pivoted detent, constant force escapement
Each pendulum is impulsed
below the bob, a platform fitted below the pendulum bob houses the jeweled
pivoted detent and the impulse pallet
The escapement is a
Berthoud pivoted detent type
Each pendulum is fitted
with a fine regulating slide with two of the steel rods
marked as vernier gauges.

indicate the seconds for each train

platforms, all of the bridges and cocks are matt finished in the

Four leveling screws with
locking nuts are to accurately level the clock

frame
