This article gives a brief description of the restoration process for the Movement clock antique we use with all our clocks.
This pendulum movement was last serviced several decades ago. Its general condition has deteriorated, and we can also see traces of dried oil around the clock pivots as well as clogged gears.
Once the movement has been completely dismantled, it is given a thorough clean, then polished in order to restore its original shine.
Here is one of the springs (there are two for each movement). They drive the hands of the clock and the chime.
Here is the movement after it has been cleaned and polished
There are two pivots on each wheel. These pivots show traces of wear due to use. In order to restore power to the gearing of the whole movement – and thus to ensure it works properly – each pivot is micro-machined.
To increase the strength and quality of the gears, we apply a very important procedure, known as bouchonnage, to correct for wear accumulated over years of operation, consisting in the placing cork of stoppers in any pivot holes that have become deformed by wear.
After the clock has been completely reassembled, it is tested over a long period of time to ensure that the movement, as well as the hour and half-hour strikes, are operating correctly.
