Keeping up with time: IWC Portugieser Constant-Force Tourbillon

IWC Constant-Force Tourbillon

steady hands

Not limited but made-to-order, this IWC model features a top-shelf 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 watches are alike. A pair of case materials feature, namely red gold (from CHF230,000, S$330,000) and platinum (from CHF255,000, S$366,000) 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.
