Slam Dunk: The H. Moser & Cie. Streamliner Pump Will Up Your Wrist Game

One of the most unexpected and fun reveals at Watches and Wonders 2026 in Geneva this month was the inventive collaboration between the creative watchmaking minds at H. Moser & Cie. and famed sneaker innovator Reebok.

I was even more delighted with the Streamliner Pump wristwatch than I expected to be, not just because I happened to have rocked a pair or two of Reebok Pumps back in the day, but because it provides a very rare example of how technology from a completely different, and I mean completely different, industry can find its way onto your wrist.

But first, some late-1980s background.

The Reebok Pump hit the scene (and the courts) in 1989, and along with some rock-solid athletic shoe chops and disruptive styling, its bulbous, orange, half-basketball-shaped pump on the tongue of each shoe allowed you to fill an internal bladder with air to customize fit, stabilize your ankle, and provide some extra bounce to your step (on-demand anytime, but ostensibly for the basketball court). A rubber release button on each tongue deflated the sneakers, returning them to their unpumped state.
 

Marketed for use on the basketball court, NBA pros like Dominique Wilkins, Dennis Rodman, and Shaquille O’Neal wore Pumps, and, hey, who didn’t want to be able to perform more like those court legends at the time?

In ensuing years, the Reebok Pump was still being made, but with a more retro marketing appeal message. All that is about to change, however, with Reebok’s focused revival of the famed trainer for this year, and – don’t ask me how it happened – H. Moser & Cie. is lending a hand, er, wrist.

H. Moser & Cie. CEO Edouard Meylan offered this insight on the collaboration: “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 rigor 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.” Couldn’t have said it better myself.
 

The innovation on this court is an ingenious system that lets you wind the mechanical movement via an iconic orange pump pusher at 8 o’clock, which augments the traditional crown and activates a rod that winds the barrel spring. Furthermore, this “pump-action” winding mechanism “inflates” the orange power reserve indicator at about 8:15 on the dial, with one press providing more than an hour of power reserve to top up the 74-hour gauge.

While the Streamliner Pump doesn’t feature a “deflation” button like the sneakers, its pump-action winding mechanism cannot be “over-inflated.” You can play with your pump as much as you like, and you will.
 

All of this pump-powered technicality, which required a complete re-engineering of Moser’s HMC 500 manual-wind small seconds movement (now dubbed the HMC 103 manufacture calibre), plays out behind the scenes under the dial, but can be viewed through open-worked bridges and a skeletonized construction via an exhibition caseback.
