IWC’s collaboration with Porsche Design began in the 1970s, bringing together Swiss watchmaking and automotive-inspired design. Founded by Ferdinand Alexander Porsche, Porsche Design introduced a minimalist, functional aesthetic that aligned perfectly with IWC’s technical expertise. Together, they created groundbreaking pieces, including the first all-black PVD-coated watch in 1972. The partnership produced highly innovative, utilitarian timepieces that remain influential and collectable in modern watch design today.

What's on Offer

A proper slice of late 20th century design thinking, this IWC Porsche Design Reference 3504.1 captures everything that made this ‘Ocean 2000’ collaboration so compelling. The full titanium construction—case and bracelet—gives it that unmistakable stealthy presence on the wrist: lightweight, functional and quietly confident.

The original black dial with Tritium markings is clean and highly legible, framed by a smooth, understated bezel that keeps the overall look sharp and balanced. The Tritium lume has aged beautifully, taking on a soft, buttery tone that adds warmth to the otherwise monochrome aesthetic. A very subtle date aperture is neatly integrated into the dial, offering practicality without interrupting the minimalist design.

The titanium bracelet is signed ‘Ocean’, linking it to IWC’s Porsche Design Ocean line—known for its focus on durability and sport functionality, and also used by military personnel as dive watches—adding an extra layer of interest.

Inside, the IWC Calibre 37521 automatic movement, adjusted to five positions, delivers reliable and precise performance with a 42-hour power reserve.

At 42mm, it wears with modern presence, yet remains incredibly comfortable thanks to the lightweight titanium. In excellent overall condition, with only light signs of wear consistent with age.

A refined, design-led IWC that remains as relevant today as it was in the 1990s. You can see why the ‘Ocean 2000’ models were also issued and used by certain military units around the globe!
