IWC Ingenieur IW3508

IWC Ingenieur 500,000 A/m Steel Ref. IW3508

The IWC Ingenieur Ref. IW3508 embodies a milestone in the history of anti-magnetic watchmaking. In the late 1980s, IWC Schaffhausen set a world record with this model that still stands today: the automatic caliber 37590 withstands magnetic fields of up to 500,000 amperes per meter – a technical achievement made possible only by the use of specially developed anti-magnetic components. What particularly distinguishes this Ingenieur is its innovative approach to magnetic protection. While earlier Ingenieur models relied on a soft iron cage that covered the dial, IWC revolutionized the concept with the Ref. IW3508: the balance spring and escapement were made from anti-magnetic materials, rendering the soft iron cage unnecessary. In our modern world, mechanical watches are constantly exposed to invisible dangers. Smartphone speakers, magnetic closures, induction chargers, and handbag clasps generate magnetic fields that can affect conventional movements. The Ingenieur 500,000 A/m offers a practical advantage for everyday use: it maintains its accuracy even in magnetically charged environments where other mechanical timepieces would long lose their rhythm. The design follows the puristic Ingenieur line of the late 1980s. The 34-millimeter stainless steel case displays clear proportions and a flat profile. The side engraving '500,000 A/m' makes the technical competence visible from the outside. The integrated stainless steel bracelet with folding clasp emphasizes the coherent overall impression. Today, the IWC Ingenieur Ref. IW3508 is considered a sought-after collector's item from IWC's Neo-Vintage period due to its short production run and correspondingly small series. Highlights at a glance: - Stainless steel case with integrated bracelet - Automatic caliber 37590 - Guaranteed magnetic field resistance up to 500,000 A/m - Short production period approximately 1989 – 1992 - Diameter approximately 34 mm - Reference: IW3508
