There are few genuinely new innovations in watchmaking and few that genuinely change how we interact with a watch. New escapements and materials might push chronometric performance ever further, but they don’t fundamentally alter the watch wearing experience. The Moser & Cie. Streamliner Pump however does just that by drawing from an unusual well of inspiration: 90s sneakers.

In the 1980s, Nikes Air technology was the benchmark for athletic footwear, a cushioned, lightweight sole filled with air. It provided a lightweight, responsive step and ever since it launched in the legendary Nike Air Tailwind, set the standard for what proper sports shoes could do. Reebok however wanted their own version.

Reebok’s Advanced Concepts team and designer Paul Litchfield came up with a different idea. Rather than using pre-trapped air cushions, Reebok would mount a miniature pump to a hidden airbag. The idea wasn’t just to rival the comfort and lightness of Nike’s Air system, but to allow the wearer to customise the fit to their needs – and in 1989, the Reebok Pump was launched.

However, it was in 1991 that the advanced shoe became an icon, during the NBA Slam Dunk contest, a small, intense competition where four players perform dunking acrobatics in front of a panel of judges. Before Boston Celtics guard Dee Brown stepped up to take his turn on live television, he kneeled down to pump up his sneakers – using the shoe’s signature orange button – and won the contest. Thus was a legend born.

The Reebok Pump dominated the 90s and did what it set out to do: outsell Nike. As footwear technology moved on however, the miniaturised pump and air cushion system couldn’t keep up. There were just better options out there. But the iconic shoe remained a touchstone of sportswear and a grail for sneakerheads the world over. It’s also the inspiration behind, of all things, Moser & Cie.’s 2026 Streamliner Pump.

There have been a lot of crossovers between sports and watchmaking in history, from reversible watches designed for polo to golf-centric G-force complications. None however have taken an idea quite as literally as Moser.

The idea is relatively simple. In addition to being able to wind your watch as usual with a classic crown, you can put energy into the mainspring by pushing a big orange button at 8 o’clock – modelled, of course, after Reebok’s iconic orange pump. This button transfers the energy from your push directly into the mainspring for an efficient, tactile interaction with the movement. One press of the button provides one hour of power reserve.

Due to the nature of the new winding system, the movement is necessarily manual wind, specifically a re-engineered version of Moser’s own HMC 500, transformed into the in-house, hand-wound HMC 103 with a 74-hour power reserve and 21,600 vph frequency. A single push adds around one hour of power reserve. Pumping it up is far from a chore though; given how satisfying the feel of that big orange button actually is, 20-odd pushes a day just isn’t enough. Fortunately, the movement is protected from overwinding, so there’s less danger of ‘over-pumping’ the watch than there is in your vintage Reeboks.

The end result is a slim movement with a genuinely new way to interact with the movement. But what case suits a sports-inspired advanced calibre like this? The Moser Streamliner of course, one whose pebble smooth case is made from matte forged quartz fibre.

This advanced material is made by cutting quartz fibre into segments and placed into a mould before being compressed and injected with resin to create a strong, light material with a unique mottled, moiré texture.  In many ways it’s similar to forged carbon but for one thing: it can be coloured. That’s why the Moser Streamliner Pump is available in two versions: deep black or crisp white.

The combination of monochrome colourways and mineral texture of the forged quartz emphasises the stone-like shape of the Streamliner like no other material. With 100m water resistance thanks to a screw-down crown with a rubber gasket and an inner titanium ‘sarcophagus’ to protect the movement from shocks, the Moster Streamliner Pump isn’t just inspired by sport – it’s built for it.

The ergonomic, 40mm x 1.4mm case (9.7mm thick if your don’t count the sapphire crystal) is paired with a matching black or white polished lacquer dial, completely unadorned except for two things: slim, unobtrusive baton indexes and the bright orange arch of the movement’s power reserve. Unlike the Moser Concept line, their logo is here, just nearly invisible in transparent lacquer. More importantly, the emphasis is placed squarely on the eye-catching power reserve, letting you watch it climb to full as you pump the watch.

While the dial is all minimalist essentialism, the caseback is the opposite. The wide, exhibition caseback gives a satisfyingly unobstructed view of the novel HMC 103. A masterclass in elegant contrast, the bridges have been given an anthracite coating, allowing the golden brass wheels and synthetic rubies to visually pop. Finished with Moser double stripes and hand-bevelled edges, this is the hand-crafted expression of Moser’s more traditional haute horology credentials. And it’s a movement made even more appealing to look at thanks to the partially skeletonised bridges revealing the pump mechanism underneath. No matter whether you’re watching from the front or the back, you can both see and feel that direct interaction with the mainspring.

To round off the Streamliner Pump’s sports credentials, both watches are fit on integrated textured rubber straps rather than the collection’s usual metal bracelet. Not only do these provide a comfortable fit, but they’re resistant to sweat – useful even if you’re more likely to be overheating courtside than shooting a three-pointer.

The Moser & Cie. Streamliner Pump is available in either black or white, with both versions limited to 250 pieces each and priced at CHF 31,360 (excluding taxes). Sneakerheads should take note that each watch comes paired with a limited edition of Reebok’s latest Pump sneaker. Finally, you can perfectly match your watch to your shoes.

Since Dee Brown made sneaker history in 1991, the Reebok Pump has been an icon of sports footwear, a system that was highly innovative and fun to use. It’s taken 35 years for the watch industry to catch up to the same idea, but in the Moser Streamliner Pump we get something that’s not only incredibly efficient, not only an impressive mechanical novelty, but something that has the kind of playfulness that haute horology often lacks. This is serious watchmaking that doesn’t take itself too seriously – and that’s a slam-dunk for Moser.
