Bulle Nº 342201
Photos by kind permission of the owner.

This clock sits on a thin polished aluminium base under a glass dome. The s/n shows it to be a very late model probably into the 1940’s. The pendulum is some sort of flat fibre rod with large decorative aluminium disks at the end. The regulation weight is hidden at the back of the clock. The suspension consists of a pivoted arbour completely unlike the early versions. The clock looks complete but is quite dirty.
The large magnets on earlier clocks have now been replaced with these much smaller cobalt magnets which are only fixed on one side leaving a large gap on the other. Some clocks have the arc of swing completely closed with a dummy magnet of brass of other non magnetic material secured to the other side of the frame. This example could allow the coil on the pendulum to be completely disengaged from the magnet and swing free. But the suspension does tend to hold the pendulum in a rigid arc. For travel the pendulum is secured by a simple hook and eye as seen in the first photo above. The photo at left shows some damage to the thin aluminium dial These dials being so thin are very prone to damage at the slightest knock. I should be able to straighten it better than what it is now though.
