I've been a vintage watch collector for over 3 decades and would like to start my first post on this forum by sharing with you my grail watch.
An 18k solid gold Patek cal. 23-300 gifted to me by my dad a few years ago.
This calibre is considered to be one of the best examples of PF's craftsmanship,
being one of the very few movements manufactured by the company to use both, an overcoil hairspring and a free-sprung Gyromax balance.
