Girard-Perregaux, ref. 99500

 

This intriguing 39 mm platinum Minute Repeater, which could be a prototype as it is numbered 0, and which is powered by cal. 9890, was sold as lot 60 last March, during Phillips' Watches Online Auction: The Geneva Sessions Spring 2025.


A truly good-looking piece, with its silver guilloché dial and blued leaf hands.

Best, Emmanuel

PS: if you're interested, I've posted more ref. 99500 and some ref. 99550 here.
