This Patek Philippe wristwatch from 1960 was likely a special order for a privileged client. It features a 23 x 33 mm 18k yellow gold case signed Guillermin and a matching 18k gold bracelet stamped “Breveté SGDG,” sized for wrists up to 19 cm. The gold dial is set with diamond hour markers and decorated with a guilloché pattern that matches the bracelet. The watch is powered by the ultra-thin manual-winding caliber 10-200, bearing the double Geneva Seal.
