The watch is a prototype of Jaeger-LeCoultre automatic watches fitted with a calibre 906 movement. What stands out here is the hacking mechanism made of green molded plastic, which stops the balance wheel when the crown is pulled out.
The automatic calibre 906 with chronometer standards was produced for a very short time only; Vacheron Constantin ordered it as an ébauche and used it for their Chronomètre Royal models.
