Blancpain 6639

The Blancpain Villeret 6639-3637-55B is a 42mm men's automatic watch with a rose gold case and a black analog dial protected by sapphire crystal. It uses a 6639 caliber self-winding mechanical movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). It ticks 6 times per second which gives the second hand a smoother movement than a quartz watch which ticks once per second. The watch should run for up to 8 days when fully wound and will self-wind when moved.
