Portugieser Rattrapante

The IWC Portugieser Rattrapante is prized for reviving the split-seconds chronograph complication in IWC’s lineup during the mid-1990s, blending classic Portugieser design cues with a highly interactive movement. Introduced under reference IW3712, this model brought the rattrapante (split-seconds) function to the brand’s iconic large-dialed dress chronograph, capturing the interest of collectors who value both technical watchmaking and elegant proportions.

Reference IW3712-01 (stainless steel, silver dial) is the archetypal version, while rarer variants like the IW3712-09 (rose gold) and limited editions for cities such as Milan and Paris command premiums due to their scarcity and unique dial details. The manually wound Caliber 76240 powers the rattrapante mechanism, offering tactile engagement via the third pusher at 10 o’clock. Case size is 41mm, with a thin bezel and clean Arabic numerals, making it versatile on the wrist despite its chronograph complication.

Price variation is driven by case material, dial color, and especially by limited edition status—city editions and early production pieces are most sought after. Servicing the rattrapante mechanism requires specialist expertise, so provenance and recent service history add tangible value. This model’s desirability is rooted in its blend of classic Portugieser aesthetics and a complication rarely seen at this price point, making it a standout for collectors focused on both function and heritage.
