The IWC Ingenieur Chronograph Silver Arrow Steel Silver Dial 45mm Ref. IW378505 pays homage to the legendary Mercedes-Benz Silver Arrow W25 with its 45mm stainless steel case and uniquely textured circular-grain silver dial, mirroring the car’s historic dashboard design. Powered by the robust selfwinding Calibre 89361, this chronograph delivers a 68-hour power reserve and features a tachymeter scale, flyback chronograph, date, and small seconds functions, ensuring precision and versatility. Luminescent index markers enhance readability against the silver backdrop, while the brown calfskin leather strap and stainless steel pin buckle provide both comfort and a vintage racing aesthetic. The watch offers water resistance to 100 meters and is finished with a scratch-resistant sapphire crystal, making it a fitting tribute to racing heritage paired with IWC’s advanced horological engineering.
