IWC Portugieser Constant-Force Tourbillon

steady hands

Not limited but made-to-order, this piece features a top-shelf IWC complication in the form of the constant-force tourbillon — a solution to power balance-related timekeeping inaccuracy 10 years in the making.

Customisations are available for case, dial, strap and engraving, ensuring that no two Portugiesers are alike. A pair of case materials feature, namely red gold (CHF230,000/RM1.01 million onwards) and platinum (CHF255,000/RM1.12 million onwards) from which to begin commission.

A double moon phase indicator shares the dial with an hour-scale power reserve and the one-minute tourbillon, while the deadbeat seconds hand ticks by overhead.
