The Ingenieur IW3808-CI (aka: IW3808CI), seen from the bench
The IWC Ingenieur IW3808-CI chronograph features a 42.30mm stainless steel case with integrated crown and antimagnetic protection of 80,000 A/m, tracing its design lineage to Gérald Genta's 1976 vision. The Swiss IWC caliber 69375 movement incorporates a column wheel chronograph mechanism, hour and minute counters with small seconds sub-dial, and date window at 3 o'clock. The 20mm lug width is structurally critical, derived directly from case proportions and ensuring proper spring bar fit without gaps or overhang.
