An early ‘oignon’ single handed verge, in good original condition, by a prestigious Paris maker.
MOVEMENT : Gilt verge movement, with a small, engraved and nicely pierced, balance bridge. The regulation is by a steel rack and worm screw, similar to the Barrow type regulators sometimes used in England at this time. The steel mainspring set up is also positioned on the top plate. Four nice baluster pillars. Signed ‘Thuret, Paris’.
There are a few scratches, and wear to the centre on the balance bridge but the movement is complete, in generally good condition and running well.
This is a single handed watch (hour hand only). The hand is driven directly from the fusee arbor (see photo).
DIAL : Nice white enamel in excellent condition, with just 2 tiny chips around the opening catch at 6. Steel hand, in good condition, which appears to be original.
CASE : Gilt brass, engraved with animals and birds around the bezel and on the back. The stem is original. The hinge is fine and the bezel snaps shut nicely. There is a little wear to the engraving on the back.
Good high dome crystal, in fine condition.
Isaac Thuret is recorded in Paris from 1669 until 1700, and was one of the most important Paris clock/watch makers in Paris during the 2nd half of the 17th century.
He was Clockmaker to the King, but of more interest, he assisted Christiaan Huygens with his development of the balance spring.
