To start the evening Larry Pettinelli, President of Patek Philippe USA, provided the guests with his insights of the Patek brand along with his thoughts on what makes Patek timepieces so special. And as a treat for everyone, he brought along a Patek 5104P Grand Complication. The 5104P is a minute repeater and perpetual calendar with leap year and a retrograde date display.
I'll post more closeup pictures of the 5104 soon.
