Blancpain, Blassus series, model: 0225-3434-53B, pt950 platinum material, 43.5mm in diameter, with a semi-open dial design, allowing a clear view of the Carrousel's operation and the hand-engraved patterns on the movement plates. Equipped with the brand's independently developed Cal.225 automatic winding movement, its core is the one-minute flight Calso mechanism. The Carrousel is similar to the tourbillon in that it is designed to counteract the influence of gravity on the accuracy of timekeeping. However, it has a more complex structure and operation mode, and is also more aesthetically pleasing. The fan-shaped date display at 9 o 'clock and the power reserve display at 6 o 'clock, with a power reserve of up to 120 hours (5 days). Limited to 288 pieces worldwide. Single watch.
