Introducing: The Unexpected H. Moser & Cie. x Reebok Streamliner "Pump"

What We Know

Leave it to watches to inform me that Reebok is bringing back one of the two coolest sneakers I never got to own as a kid (yes, Heelys were the other ones). The Pump sneaker is returning in 2026, and to celebrate, the shoe brand is partnering with H. Moser on a weird and fun collaboration centred on its integrated bracelet watch, the Streamliner.

One quick look at the watch and the idea is pretty self-explanatory. There's an orange power reserve indicator at 8 o'clock on the black or white polished dial. Nearby, on the same 8 o'clock segment of the case, is the recognizable "pump" button as you'd find on the tongue of Reebok's sneaker. For each press of the "pump" pusher (literally), you get about 1 hour of power reserve as the internal mechanism winds the watch. If you hit the max power (74 hours or 74 pumps), you can keep pressing that button just to get the enjoyment out of the fidget of it all.

The cases, measuring 40mm by 11.4mm (with the crystal), are made in the futuristic choice of black or white forged quartz fibre, with colour-matched straps as well. The quartz is wrapped around a titanium inner case (or a "sarcophagus" as the brand calls it) with a titanium caseback ring for the sapphire caseback. There's still a big metal crown at 3 o'clock for setting the time, and the entire watch is water resistant to 100m. The dials feature applied indices while the hands have anthracite grey or white Globolight inserts, emitting a green glow in low light.

You can't just look at a watch and say, "Sure, we can just pump up the jam here." The HMC 500 small seconds movement was modified into a manually-wound calibre. Or rather, a manually pumped calibre. The anthricite-finished bridges with Moser double strips are now partially skeletonised as well. You get 74 hours of power reserve with 31 jewels on a movement running at 21,600 bph.

If you want to be one of the kids with the pumped up kicks—er, well, watch—then you should know that this really rad (they were still saying that in the 1980s, right) watch is limited to 250 pieces per style. Both come in at 31,360 CHF.

What We Think

If we're ranking my favourite shoes I never got to own, judging by my advancing age and general coordination, getting Pumps (with the internal inflation mechanism to cushion my ailing joints and ankles) seems like the safer bet than Heelys, and, to my knowledge, no one is making a Heelys-themed watch. This is fun and creative, which is exactly what Moser does.

They do serious watchmaking but don't take themselves too seriously. And gimmick aside, there's some really cool horology behind the new release. I'm actually curious if it's possible to get a closer look at the winding mechanism. It sort of reminds me of a "trip" repeater that chimes when you press a button, rather than sliding a case slider.
