David Walter’s Double Pendulum Table Clock is an emulation of the Janvier clock currently on display at the Patek Philippe Museum, Geneva and is the first time that the justly famous Janvier clock has been recreated.
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.
