In 2006, Blancpain came out with their Léman Tourbillon Semainier Grande Date watch. It's got a self-winding movement and a cool tourbillon escapement, plus a unique week number display. On top of that, it also shows the date, day, and power reserve like most watches do.The model number for this particular watch is 2925-3630-53B. It's got a fancy red gold case and a pretty opaline dial. Plus, it comes with a stylish alligator strap that's lined with rubber. But be quick, it's a limited edition of only 188 pieces.
