The firm of Girod was founded in 1865 by the brothers Leon and Auguste Girod in the Morbier Jura region of France where they manufactured a range of mechanical clocks including wall mounted Westminster chime clocks and floor standing long case clocks

Later models dating from 1950; have small battery powered movements utilizing a mechanically switched magnetically driven balance wheel with an inverted form of the Sully escapement. ODO was also big in domestic clocks and also made battery operated clocks based on Girod patents.

Although many of these clocks appear similar, there are many minor differences between movements. The trademark for Girod has a large letter G around 'irod' that is not immediately obvious as part of the name.  This sometimes causes confusion and these clocks may be described as Irod rather than Girod.

Clock 2 has images of dismantling and a microset trace. The spike in the 17 hour trace is acoustic interference at the sensor, not a change in rate of the clock. 

The Brillie Delvinotti movement is superficially similar in concept with a reverse Sully escapement but a smaller simpler worm drive train. Images are in the Brillie folder.
