Portugieser Perpetual Calendar Tourbillon

Portugieser Perpetual Calendar Tourbillon

The Portugieser Perpetual Calendar Tourbillon combines two horological complications on the dial.

Portugieser Perpetual Calendar Tourbillon

The Portugieser Perpetual Calendar Tourbillon combines two horological complications on the dial.

Portugieser Perpetual Calendar Tourbillon

The Portugieser Perpetual Calendar Tourbillon unites two sophisticated Haute Horlogerie complications. The tourbillon, made of 82 individual parts, weighs only 0.635 grams. The "whirlwind" causes the balance wheel to rotate around its own axis, compensating for the effect of gravity on the oscillating system and increasing accuracy. Requiring no correction until 2100, the perpetual calendar automatically recognizes the different lengths of the months and leap years. The moon phase display is so precise that it will deviate by one day only after 577.5 years. The self-winding IWC-manufactured 51950 calibre boasts a power reserve of 7 days. The case is made of 18-carat Armor Gold®. Thanks to a modified microstructure, this material is significantly harder than traditional gold alloys. The blue dial, gold-plated hands and the 18-carat gold appliqués underscore the maritime character of this special edition, which is limited to 50 pieces and sold exclusively in IWC boutiques. The timepiece is fitted with a blue alligator leather strap.
