IW516501 Replica Watch IWC Portofino Hand-Wound Tourbillon Retrograde On Sale
The IWC Portofino series of manual winding tourbillon retrograde watches (IW516501) is the first Portofino timepiece with a tourbillon. The balance wheel, the pawl lever and the escape wheel are assembled in the same tourbillon frame, which rotates once a minute around the axis. The newly developed "stop tourbillon" makes the time setting of the watch accurate to the second. IWC has also improved the geometry of the pawl lever and the escape wheel, combined with diamond-coated silicon to reduce the friction, allowing the Model 59900 manual winding movement to provide up to 8 days of power reserve after full string.New Luxury Replica Hublot Classic Fusion Watches for you to choose.
