The relatively flat executed movement is driven by a spring barrel in combination with fusee and chain. There is also Harrison’s maintaining power which ensures an auxiliary spring to drive the wheel train while the chronometer is wound. In this way the movement doesn’t loose time because the driving power would fall away when the clock would be wound. The large split bi-metallic balance has ten adjustment screws and has a diamant end stone. The balance spring is of the helical type. The chronometer has fixed winding with fold out arches. This type of winding is often named ‘Barraud’s patent winding’. Although there is no patent known for this device.
The three-part mahogany wooden case has brass fittings and handles. An ivory plate with the number 2/707 is mounted on the front. The old patina of the wood and brass has been beautifully preserved.
