With a gold filled case and very nice automatic movement, this Girard-Perregaux Gyromatic would have not been a cheap watch.  Model reference B1773.

HOW DO WE DATE THIS WATCH?

Girard-Perregaux first started making watches in 1791.  The movement used in this watch was only in production for four years, between 1950 and 1954, so this watch would have been made during that time.  We have opted for circa 1952, being a mid point year.

CONDITION

The automatic movement used in this watch is signed for Girard-Perregaux, but it is heavily based on the ETA 1256 (which was the first automatic movement made by ETA).  Given it was ETA’s first automatic, there is a chance this was the first Girard-Perregaux automatic too.  It is finished to a higher standard than others we have seen, but Girard-Perregaux are a premium brand so you might expect that.  The case is 10k gold filled, and gold filled cases are much harder wearing than gold plated cases as the gold is thicker.  That said, there is still some wear to the case.  The dial is original and has applied hour markers, as well as a 1/5th second markers on the minute track.  The pointy lugs are a nice design touch.   The strap is new, and could be swapped for a different colour or material if preferred.  The watch is signed on the case, movement and dial.

This watch will be supplied with our branded presentation box and our Certificate of Authenticity.
