SL1832 — 1976, Gérald Genta, 50 years on

SL1832: that reference from 1976 frames the new release. Gérald Genta designed the original, and IWC now marks the 50th anniversary with a new Ingenieur Automatic available in two sizes.

What we know

Details published so far are sparse but specific. The link to the 1976 Ingenieur SL1832 is explicit in IWC’s announcement. The new model comes in two case sizes and is presented as a celebration of that Genta-derived design.

As Fratello Watches – The Magazine Dedicated To Luxury Watches first reported, IWC has revisited the Ingenieur SL’s design for this anniversary release.

• Original reference: IWC Ingenieur SL (SL1832), introduced in 1976.
• Anniversary release: a new IWC Ingenieur Automatic issued to mark 50 years.
• Offerings: two case sizes (IWC is positioning size choice as a key decision).

Stylistically, the new Ingenieur is explicitly tethered to the SL1832’s lineage. The announcement frames the release as part heritage nod, part modern reinterpretation. IWC’s message puts design continuity front and center rather than radical technical reinvention.

For buyers and collectors: this is a size play. Expect conversations to split between those who prefer a close-to-original, vintage-proportioned option and buyers who want a contemporary wrist presence. The market response will tell whether the Ingenieur’s Genta association rekindles strong secondary-market interest for both sizes.
