I feel that a Rolex Submariner movement would probably still be better in terms of long-term accuracy and durability. But it's not a special movement. The Octo Finissimo's movement is a very special high horology (or haute horlogerie) movement and will probably be more temperamental. But even Ferrari engines are very reliable and relatively low maintenance nowadays. Bulgari has certainly shown me that they're heavily invested in the watch industry. They really are making wonderful creations and spending a lot of time and money to make these record setting creations. Obviously, they're well funded by a very profitable and lucrative jewelry division. Around the 10.000 Euro level, I see that they're probably the strongest contender for someone who wants a great watch. It's one of the few watches at this price level that's a true "high horology" (or haute horlogerie) piece. And made in the Vallée de Joux is definitely a sign of quality. Even the best Geneva based manufacturers (Vacheron Constantin and Patek Philippe) have offices and subsidiaries in the Vallée de Joux. The Vallée de Joux is also home to Le Brassus (home of Blancpain and Audemars Piguet) and Le Sentier (home of Jaeger-LeCoultre, Bulgari, Philippe Dufour), and Breguet calls the Vallée de Joux home as well half a kilometer away from Bulgari although I'm not sure if Breguet is technically in Le Sentier. Definitely go try the Finissimo and see if you like it on your wrist!
