H. Moser & Cie. arrives at Watches & Wonders 2026 with one of the most versatile lineups of the week — from a Reebok collaboration that's genuinely funny and technically brilliant, to one of the most complicated watches the brand has ever made. Tim Mosso goes hands-on with the full collection.

The Streamliner Pump is the headline. Built in collaboration with Reebok to mark the return of the Pump sneaker, it replaces the traditional crown with an anodized orange pusher at 8 o'clock. Each press winds the movement and adds roughly one hour of power reserve, tracked live on the dial. The HMC 500 has been fully re-engineered into a manual-winding HMC 103 caliber to make it work. The 40mm case is built from forged quartz fiber — lighter than carbon, with a unique moiré pattern on every piece. Limited to 250 pieces per colorway. Every purchase comes with a Reebok Pump sneaker made for the collaboration.

H. Moser & Cie. brings the Streamliner's integrated case-and-bracelet design down to 34mm and 28mm for the first time — both in steel, with frosted fumé dials in silver and burgundy respectively, and fully mechanical movements.

The Streamliner Tourbillon Concept Ceramic — released earlier this year — pushes one of Moser's signature complications into ceramic for the first time, combining the Streamliner's fluid integrated design with the Concept's stripped-back dial philosophy and the brand's flying tourbillon.

The Endeavour Minute Repeater Cylindrical Tourbillon Skeleton is the technical crown jewel — uniting three of watchmaking's most demanding complications in a single skeletonized watch: a minute repeater brought to the dial side, a flying tourbillon, and Moser's in-house cylindrical hairspring.

The Endeavour Tourbillon Skeleton, also released earlier this year, is a fully skeletonized take on the Endeavour that makes the flying tourbillon the undeniable focal point, with open architecture that rewards extended wear and close inspection.
