In this comprehensive guide, quattro meticulously details three often-overlooked Patek Philippe references: the 5009, 5010, and 5024. His original post serves as an invaluable resource for collectors seeking to understand the subtle yet significant distinctions between these rectangular timepieces, all united by the reliable Caliber 215. This article illuminates the nuances of case dimensions, dial configurations, and metal variations, making these vintage-inspired models discoverable for a new generation of enthusiasts.
TeutonicCarFan's thread from yesterday concerning the ref. 5024J gave me the idea to make a thread regrouping three very close Patek Philippe references, all powered by
caliber 215: ref.
5009,
5010 &
5024.
I could have included the ref. 5124, but it's powered by a different shaped caliber (25.21 REC PS) and I've already included it in a
thread concerning three Gondolos.
Enjoy!
