Bulgari Octo Finissimo: New Movement Change?

Key Points from the Discussion

• The changes to the BVL138 movement, particularly the larger winding rotor and altered bridge layout, might be driven by Bulgari's strategy to standardize the movement for future complications, such as the perpetual calendar, by adapting all versions whether they drive secondary complications or not.
• The original BVL138 movement, like many micro-rotor automatics, was known to have winding efficiency issues, with some owners reporting watches stopping even after active wear. The new movement could be Bulgari's attempt to address these reliability concerns.
• Introducing a revised movement into existing lines without official announcement or a change in caliber number is highly unusual and raises questions about brand transparency, especially if the changes are substantial and potentially affect performance or perceived quality.
• While the visual changes are dramatic, the exact functional implications are not yet clear. One theory suggests the modifications could be a cost-cutting measure, similar to how other brands have made subtle changes to components over time.
• Despite potential winding issues with the older movement, some owners report excellent durability and timekeeping, even under active use, suggesting individual experiences can vary widely.
• The lack of a new caliber number for a visibly different movement is inconsistent with practices seen in other high horology brands, such as Patek Philippe, who would typically assign a new reference even for relatively minor modifications.
