The concept of the “jump hour” and “wandering hour” has been used in horology since the 18th century, however it was not until the early twentieth century watch makers brought them to the forefront and made some of the most classic and timeless watches known today. The mechanism allows for a clean dial with an aperture for the hour and the minutes recorded either through a secondary aperture or like the present Vacheron Constantin Saltarello, the use of retrograde hands. The watch is reduced to a modern simplicity that transcends time.

This example number 123 out of 200 is in excellent original condition. The case remains unpolished with only very slight wear. Complete with its original presentation box and certificates, the Saltarello is a stunning example of the jump hour mechanism.
