The IWC Schaffhausen GST Split-Seconds Chronograph reference IW371523 is a highly sophisticated and technically impressive timepiece, featuring one of the most prestigious complications in horology: the rattrapante, or split-seconds chronograph. Designed for precision timing, this model stands out as a true collector’s piece within IWC’s professional watchmaking heritage.
Crafted in stainless steel, the 43 mm case and integrated bracelet offer a robust and cohesive design, combining durability with a refined industrial aesthetic typical of the GST line. The white dial provides a clean and highly legible display, enhanced by contrasting sub-dials, applied hour markers, and luminous hands for optimal readability. The chronograph layout includes both standard and split-seconds functionality, allowing the measurement of intermediate times with exceptional precision.
At the heart of this pre-owned luxury watch is the IWC calibre 79230 automatic movement, based on the robust Valjoux 7750 architecture and extensively modified by IWC to incorporate the rattrapante mechanism. This complex movement delivers reliable chronograph performance with a power reserve of approximately 44 hours, showcasing IWC’s engineering expertise.
Protected by a sapphire crystal and built for performance, the GST Rattrapante Chronograph combines technical mastery with everyday usability.
This certified pre-owned IWC GST Split-Seconds Chronograph is presented in new condition, preserving its excellent overall appearance. It is delivered as watch only, without original box or papers.
A rare and highly desirable complication, the IWC GST Rattrapante IW371523 is a remarkable addition to any serious luxury watch collection.
