IWC Ingenieur Chronograph Edition W125 is one of the most distinctive modern Ingenieur releases, blending 1930s racing heritage with IWC’s newest watchmaking technology. This review takes a full look at its titanium construction, Caliber 69370 in-house movement, refined dial layout, and overall wearing experience.
Design Inspired by the Mercedes-Benz W125
The IWC Ingenieur Chronograph Edition W125 draws direct inspiration from the legendary Mercedes-Benz W125 “Silver Arrow”. The lightweight titanium case echoes the aesthetics of pre-war racing machines, offering both robustness and comfort on the wrist. The silver-white dial complements the titanium material, producing a clean, instrument-like appearance.
The dial follows a traditional Ingenieur layout: the date window and small seconds sit at 3 and 6 o’clock, while the chronograph counters are positioned at 9 and 12 o’clock. This balanced design enhances readability for both everyday wear and timing functions. Around the outer edge of the dial is a tachymeter scale rated to 1000 meters, reinforcing the racing theme.

In-House Caliber 69370 Movement
Powering the 42mm case is IWC’s own Caliber 69370, a modern automatic chronograph movement built from 200 components. It features a durable and precise column-wheel mechanism that ensures smooth chronograph operation. When adjusting the time, the small seconds hand automatically resets to zero — a detail that improves accuracy and user experience.
The movement runs at 28,800 vph and delivers a 46-hour power reserve. With 36 jewels and IWC’s modern construction techniques, Cal. 69370 is engineered for reliability, making it suitable for both collectors and everyday use.
Case Size, Wearability & Strap
The watch measures 42mm in diameter and 15mm in thickness, giving it a sporty wrist presence without feeling heavy, thanks to the titanium case. It is paired with a black calfskin strap with diamond-pattern stitching, enhancing both comfort and visual texture.
This limited edition of 750 pieces adds exclusivity and collector appeal, making it a standout among modern IWC special releases.
