Girard-Perregaux ref. 99550 “Golden Bridges” Tourbillon, Minute Repeater, Piece Unique

Up for grabs is a Girard-Perregaux “Golden Bridges” Ref. 99550.0.71.1530.

A piece unique executed in platinum, confirmed by the Girard-Perregaux Certificate of Authenticity.

This reference combines a manual-wind tourbillon with a minute repeater complication, housed in a 39mm platinum case measuring approximately 12mm thick.

The watch features a highly attractive blue guilloché dial.

It is fitted on a generic strap with the original Girard-Perregaux folding clasp.

Accompanied by the Girard-Perregaux Certificate of Authenticity. No box.
