In the late 1980s, Reebok introduced the Pump sneaker, quickly becoming an icon for an entire generation. The reason for its success? The Pump was never just a sneaker. It was an attitude, a statement that performance could go hand in hand with pleasure. And above all, it was a gesture that became cult: a simple press to connect with the shoe, adjust it, personalise it, and feel it come alive.

H. Moser & Cie. shares with Reebok this mindset of elegant outsiders, convinced that luxury is at its best when it does not take itself too seriously. It is this playful sophistication that the two brands set out to celebrate by transposing the Pump gesture into watchmaking. Launched at Watches and Wonders 2026, the Streamliner Pump brings play back to the centre and breathes new life into the industry.

THE PUMP GESTURE, REIMAGINED IN WATCHMAKING

As Reebok prepares the return of the Pump in 2026, H. Moser & Cie. imagined an unexpected bridge: winding a mechanical movement using the iconic orange button. The reference is obvious, but the execution is delightfully precise. Replacing the traditional crown, an anodised aluminium pusher transmits the energy of each press to the barrel spring, simultaneously activating the power reserve indicator. An ingenious mechanical choreography unfolds beneath the surface, visible through openworked bridges and a fully skeletonised rack.

One simple press is enough for more than one hour of power reserve. And once the spring is fully charged, there is no need to stop: the button can still be pressed, purely for pleasure — because some gestures need no justification.

A PUMPED MOVEMENT

To create this calibre, H. Moser & Cie. completely re-engineered the automatic HMC 500 small seconds movement, transforming it into a manual-winding calibre. Compact and remarkably slim, it lent itself naturally to this ambitious technical reinterpretation, in which every component finds its place with precision. The sapphire case-back reveals the result: a sharpened, lightweight engine designed to accommodate the Pump system while preserving the brand’s minimalist DNA.

WHEN QUARTZ BECOMES A NOBLE MATERIAL

The Streamliner Pump is offered in two versions, each limited to 250 pieces. Its case is crafted from a material rarely seen in watchmaking: forged quartz fibre. Purer and whiter than glass fibre and resistant to UV exposure, quartz fibre can be coloured, offering a level of aesthetic freedom that carbon does not allow. Cut into segments, placed in a mould and compressed, it is combined with injected resin before undergoing two successive curing cycles. This process gives rise to matte cases with a unique moiré pattern — no two are alike. Inside, an internal titanium “sarcophagus” acts as a protective exoskeleton: it shields the movement, ensures water resistance to 10 ATM, and secures the integrated rubber strap.

On the wrist, the watch measures 11.4 mm in thickness, a confident presence made surprisingly light thanks to the quartz fibre and to the titanium elements, such as the sarcophagus and the caseback, this one finished with a DLC coating on the darker version. The lacquered dial, available in black or white depending on the reference, unfolds as a perfectly polished surface. The hands, highlighted with anthracite grey or white Globolight® inserts, emit a green glow in low light, while the power reserve is indicated by an orange disc.

PLAYFUL LUXURY, WATCHMAKING WITH BREATH

Since 2013, H. Moser & Cie. has claimed a distinctive altitude, as explained by Edouard Meylan, CEO of the brand: “We take watchmaking very seriously, but we cultivate our image as the ‘cool kid’ of haute horlogerie. The Streamliner Pump illustrates this philosophy: a sophistication that smiles, a rigour that leaves room for insolence, and a mechanism that invites you to touch, press and feel. At a time when watchmaking is multiplying technical feats, this watch reminds us that innovation also means reintroducing play, surprise and breath.”

“Collaboration has always been a big part of how Reebok shows up in culture. The Pump was one of the most innovative shoes of its time, and the fact that it’s still relevant more than 35 years later says a lot about how iconic it is.” said Matt Salter, Executive Vice President, Partnership Marketing at Authentic Brands Group, owner of the Reebok brand. “H. Moser & Cie. has a reputation for incredible craftsmanship and bold design, which makes them a perfect partner for a project like this. Getting dressed starts with the shoes you’re going to wear and the finishes with putting on your watch. This collaboration was a chance to reinterpret the Pump through that lens.”

FROM SNEAKER TO WATCH… AND BACK AGAIN

Like an echo returning after travelling through time, H. Moser & Cie. and Reebok have also jointly created an exclusive Pump sneaker, reserved for Streamliner Pump owners and close friends of the brand. The sneaker becomes the answer to the watch, a mirror of the original gesture: the Pump becomes a timepiece, then returns to its original form. A confidential capsule designed for those who like to walk with the same elegance as their ideas.

The Streamliner Pump is a creation from the Moser Exploration LAB™, a place where unusual ideas are given room to grow.
