Reasons to Bid

When IWC introduced its second-generation Ingenieur SL models in the early 1980s, the manufacturer responded to evolving tastes by offering a slimmer 34mm case (approximately 8.8mm in thickness), often referred to by collectors as the ‘Skinny Ingenieur’. This version preserves the core elegance and design identity of the original Gérald-Genta-designed integrated bracelet sports watch, but in a size more suited to everyday wear. The stainless-steel case retains the signature five-screw bezel and integrated bracelet architecture, and despite the reduced diameter, the watch maintains notable wrist presence thanks to its solid bracelet construction. Powering this variant are automatic movements from the ETA-based Caliber 375 family, delivering reliable daily performance and reflecting the technical direction of the Ingenieur line during the period. As a result, this extremely well-kept example offers the same recognizable Ingenieur character as the jumbo, but with proportions that are more understated and versatile for regular use.
