Hi J L,

Thank you for contacting Mearto with your appraisal inquiry.

The "Medaille d'Or" mark on the back is that of Samuel Marti, who was a prominent French clockmaker active during the 19th century. He is best known for crafting high-quality mantel clocks and other timepieces. His clocks frequently featured intricate designs and incorporated high-grade materials.

His movements survive in a variety of different cases - which may or may not have been made by him as there were clockmakers in his time who just made the works - but most sell for between $600-900.

Based on the photos and information provided, and subject to examination, this is:
