Key Points from the Discussion

• The Panerai Caliber P.900 is identified as a renamed and improved OP XXXIV, both engineered by ValFleurier. The discussion raises questions about the specific similarities and differences between the P.900 and movements like the Baumatic BM12-1975A, particularly concerning jewel count, power reserve, and overall quality perception.
• Insights from Perezcope.com suggest that the OP XXXIV, powering various Luminor Due and Submersible models, was developed by Manufacture Horlogère ValFleurier for Richemont's entry-level brand Baume & Mercier, later adapted for Panerai.
• A common 'cheap-shot' argument regarding the low production cost of non-precious metal luxury watches (e.g., USD 350 for Panerai, USD 650 for Rolex) is debunked by emphasizing that these figures exclude significant R&D investments, which are crucial for luxury brands and movements developed by entities like ValFleurier.
• Concerns are raised about Panerai's 'steps backwards,' such as the removal of hacking seconds from the 9010 movement and the use of undecorated movements hidden behind closed casebacks, without transparent communication from the brand.
• The eSteel cases for the new Submersibles contain at least 52% by weight of recycled metals, demonstrating Panerai's flexibility with steel grades, a contrast to brands with stricter material purity standards.
• A collector expresses disappointment over Panerai's recent decisions, specifically the unannounced removal of the hacking mechanism from the 9010 movement and the use of undecorated movements in expensive watches, despite still appreciating their existing Panerai collection.
