The Portugieser Chrono-Rattrapante in 18k white gold is one of the rarest versions of IWC Schaffhausen’s historic Portugieser collection. It combines the family’s essential design, with a highly legible dial, large Arabic numerals and leaf hands, with one of the most refined chronograph complications: the rattrapante, or split-seconds.
The model
Two references are known in white gold, each produced in a limited edition of 100 pieces: the IW3712-08 with black dial and the IW3712-09 with silver dial. The case measures approximately 40.9 mm in diameter and 12.3 mm in thickness, with an anti-reflective sapphire crystal and a solid caseback; water resistance is approximately 30 metres.
The movement
The self-winding IWC calibre 76240 drives hours, minutes and a central-seconds chronograph with a rattrapante function. The two chronograph seconds hands start together, one above the other: one can be stopped to read an intermediate time while the other continues to run, and the two are then rejoined. It is a complication that is complex to build and to adjust, and for this reason it remains relatively rare.
A small production run, a precious-metal case and a significant complication make this Portugieser a piece sought after by IWC collectors.
