Blancpain Ladies Tourbillion Grande Date watch, round 18kt white gold case (40mm diameter, 12.77mm thick) set with blue sapphires and transparent caseback, white alligator leather strap lined with alzavel, bezel set with two rows of blue sapphires, brushed white gold dial set with blue sapphires and with steel hands, large date indication window at 6 o'clock, exposed tourbillon carriage at 12 o'clock, 35 jewel Calibre #6925 self-winding automatic mechanical movement, scratch resistant sapphire crystal, 168 hour power reserve, water resistant to 100 meters.
Blancpain has perfected and miniaturized this masterpiece of the watchmaking art. Its power reserve eliminates the necessity of daily winding and guarantees optimum precision due to the slower more regular detent of its barrel spring. Today, as in 1801, the Tourbillon represents one of traditional watchmaking?s masterpieces. Paying tribute to this exceptional invention, Blancpain presents Tourbillon watches water-resistant to 30-100 meters.
