First introduced in 1989, the Reebok Pump redefined performance footwear with a bold idea: a shoe you could inflate for the perfect fit. Instantly recognisable by its signature orange pump button, it became a cultural icon, worn by elite athletes and embraced by street culture. More than a technical innovation, the Pump embodied a spirit of playful experimentation, where interaction was part of the experience.

That same spirit now transcends disciplines, from the foot to the wrist. Each watch is paired with a limited edition of the new shoe, extending this iconic concept into a new dimension of interaction and design.

The case is crafted from forged quartz fibre, a material rarely seen in watchmaking. Lighter than it looks yet remarkably resistant, it offers a unique aesthetic freedom, forming a matte surface with a distinctive moiré pattern: no two cases are alike. Inside, a titanium “sarcophagus” protects the movement, ensures water resistance to 10 ATM, and anchors the integrated rubber strap. A bold construction, engineered for both performance and comfort.

At its heart beats the hand-wound manufacture calibre HMC 103, integrating the Pump system. Compact and precise, it delivers a minimum 74-hour power reserve and features an original Straumann® hairspring. Visible through the caseback, the movement reveals a refined architecture adapted to this unconventional winding mechanism. Technical ingenuity, driven by playful interaction.
