The IWC for Prada GST: When Schaffhausen Met Milan on the Open Water

Long before watch-and-fashion collaborations became an industry reflex — before every brand with a marketing budget was partnering with a streetwear label or a celebrity chef — IWC and Prada quietly did something genuinely interesting. In 2002, they made a chronograph together, and then mostly forgot to talk about it.

The backstory matters here. Prada CEO Patrizio Bertelli wasn’t dabbling in sailing — he was obsessed with it. Luna Rossa, Prada’s America’s Cup challenger, had been competing seriously since 2000, and the ref. 3708 was produced in a limited run of 2,000 pieces to mark their campaign for the 2003 America’s Cup. This wasn’t a logo-swap exercise. It came from an actual relationship between a fashion house and competitive sailing, which happened to produce a watch.

And what a watch. The GST platform — IWC’s integrated-bracelet sports chronograph from the late ’90s — was already a quietly confident design, the same architecture that would eventually evolve into IWC’s Aquatimer line. At 40mm in steel, it wears like a modern watch despite being over two decades old. Under the hood sits a modified Valjoux 7750 with the running seconds removed, giving the dial a cleaner bi-compax layout instead of the typical three-register arrangement. That editorial decision — removing a complication to make something feel more intentional — is very Prada, if you think about it. Reduction as a design statement.

The dial is where the collaboration really lives. Silver and black in a way that feels considered rather than busy, with steel baton indices and just enough contrast between the registers and the main dial to give the eye somewhere to travel. There’s a day-date window that manages not to clutter things up, which is harder to pull off than it sounds on a chronograph. It’s restrained in the way that Italian design often is at its best — nothing shouting, everything in its right place.

What makes these fascinating now is the context. Most early 2000s fashion-watch collaborations have aged terribly. The IWC for Prada hasn’t, partly because both parties brought real competence to the table — IWC wasn’t lending its name to a fashion accessory, and Prada wasn’t just slapping a triangle logo on a dial. It remains the only collaboration between Prada and IWC Schaffhausen Bachmann-scher, which only adds to the appeal. They did it once, got it right, and moved on.

This particular example — reference 370802, one of those 2,000 pieces, in excellent condition — is currently listed at WatcheSmiles for $25,000. Drop us a line if it catches your eye.
