IWC IW371508 GST Chrono-Rattrapante SS Gray Dial

The IWC GST Chrono‑Rattrapante Ref. IW371508, introduced in 2001, stands as a pinnacle of IWC’s technical prowess within the GST line. Its 43 mm stainless steel case houses the automatic Caliber 79230, a robust split‑seconds chronograph movement with day and date indications, offering approximately 44 hours of power reserve. The rhodium‑plated gray dial is both elegant and legible, featuring luminous indices and hands, and is protected by an anti‑reflective sapphire crystal. With a screw‑down crown and a water resistance rated at 10 ATM (100 m), this model balances sporty durability with refined aesthetics. The integrated stainless steel bracelet underscores the watch’s cohesive design language, while the third pusher at 10 o’clock activates the rattrapante function—an advanced complication that appeals to seasoned collectors. Though not a limited edition, its combination of split-second complexity, early‑2000s production, and the GST heritage makes it a rare and highly sought‑after piece among enthusiasts. Excellent condition with IWC box and undated papers. IWC just fully serviced this Double Chronograph in Q2/2026.
