This
burgundy dial
variant of the regular
Patek Philippe Weekly Calendar Calatrava was made in
2024 to celebrate
50 years of
partnership with Austria-based
Juwelier Heldwein.
The ref. number is 5212A-010 as opposed to the 5212A-001 of the regular version.
The sapphire case back says “Patek Philippe & Juwelier Heldwein – 1974-2024 – 50 years of collaboration”, but I have been unable to find some photos of it.
Only 20 pieces were made.
Do you like it?
Best, Emmanuel
