There is a delicious paradox in the story IWC Schaffhausen tells as it celebrates 50 years of the Ingenieur SL: the house pays tribute to a watch that, when it was launched, did not find the commercial success expected.
In 1976, IWC introduced the Ingenieur SL, reference 1832, created by designer Gérald Genta at the height of his creative period in the 1970s, a decade in which steel sports watches with integrated bracelets were establishing themselves as a category in their own right in Swiss watchmaking. Despite an aesthetic ahead of its time, the Ingenieur SL did not immediately find its audience: between 1976 and 1983, only 598 examples were produced. It would take several decades for collectors to rediscover the piece, now regarded as one of the most sought-after models in the house’s history.
It is this reference 1832 that served as the blueprint for the modern Ingenieur, relaunched in 2023. Its bezel held by five functional screws, its grid-patterned dial and its integrated bracelet take up the visual codes of the Ingenieur SL, while adding more refined ergonomics and finishing. To mark this half-century, IWC unveils two limited editions of the Ingenieur Automatic, available in 40 and 35 millimetres, each limited to 1,150 pieces.
Both watches stand out with a brushed silver dial, inspired by a rare variant of the 1970s Ingenieur SL: while reference 1832 is best known for its grid-patterned dial, IWC also produced a version with a silver dial and a brushed finish, which remained more confidential. One further detail marks the anniversary: the small lightning bolt that usually appears beneath the name “Ingenieur” has been replaced by the number “50”. “Fifty years have passed since my father created the Ingenieur SL, and I am still amazed to see how much his work continues to inspire so many people decades later,” says Alexia Genta, daughter of Gérald Genta and co-founder of the Gérald Genta Heritage Association.
On the technical side, the 40 mm model is fitted with the manufacture calibre 32111, equipped with a double-pawl winding system that provides a 120-hour power reserve, protected by a soft-iron inner cage as on the original Ingenieur SL. The 35 mm model reveals, through a sapphire case back, the calibre 47110, adorned with Geneva stripes and a gold-plated rotor. “With its distinctive and bold design, the Ingenieur SL shaped both Gérald Genta’s career and the history of IWC Schaffhausen,” sums up Christian Knoop, the house’s creative director.
The gesture sums up fairly well what contemporary watchmaking does best with its own archives: turning a commercial failure into an aesthetic matrix, provided it is given the time to find, several decades later, the audience able to read it.
