The Vintage Wrist Watch Company has dated this piece to the 1920s.
In 1901, the two families of the founders of Favre Leuba and Zenith were privately quite close and Henry Auguste Favre (Favre Leuba), who already owned a successful branch in Bombay, took over the distribution for George Favre-Jacot (founder of Zenith) in the region India/Burma. During the long co-operation between the two companies, which lasted until the 1960s, several watches, especially high-class chronometers, were not only designated Zenith but also Favre-Leuba on the dial.
The movement is signed Zenith, and it has the serial number 2,893,811 which dates it back to 1929. The movement is protected by an inner hinged dust cover (which has some unevenness).

The watch measures 34mm diameter excluding the winding crown and the fixed wire lugs. The case is 925 silver and there are Swiss hallmarks inside both of the case backs. The inside of the case back also has the Zenith stamp. The back of the watch has monogrammed initials. There are a couple of small indentations to the back of the watch and some other small marks but overall it is very acceptable for such an early piece. It seems that the hinge and original bezel have been removed and replaced with a later, non hinged bezel.

The watch glass is in good order.
The enamel dial is signed Favre Leuba & Co, Zenith. There are a few hairline cracks towards the perimeter of the dial. Blued steel hands, a subsidiary seconds dial and an outer minute track.
A later vintage leather strap has been fitted.
