H. Moser & Cie. is arriving at Watches and Wonders 2026 with four releases that, taken together, capture exactly what makes the Neuhausen-based manufacture difficult to categorise. There is high horology of the most demanding kind, a minimalist perpetual calendar in an unusual metal, two compact dress watches that make a quiet argument for restraint, and a collaboration with Reebok that winds a mechanical movement using a sneaker's inflation button.
Endeavour Minute Repeater Cylindrical Tourbillon Skeleton
The most technically ambitious piece of the four is the Endeavour Minute Repeater Cylindrical Tourbillon Skeleton (ref. 1909-0500). The headline combination - a fully skeletonised minute repeater paired with a one-minute flying tourbillon - is demanding enough on its own. What makes this piece distinctive is where Moser has placed the repeater's hammers and chimes: On the dial side, fully visible, rather than concealed within the movement. This required a complete rethinking of the construction, with curved chimes positioned on the same plane and volumes precisely adjusted for acoustic performance.
The 40 mm titanium case has been chosen and engineered with sound in mind. The case middle has been hollowed to function as a resonating chamber, and the sliding bolt runs on a Teflon runner integrated into the main plate to preserve space. Titanium's low damping properties mean vibrational energy is preserved rather than absorbed, producing a chime that is fuller and longer than a steel or gold equivalent would typically allow.
At 6 o'clock, the one-minute flying tourbillon features a cylindrical hairspring - a form inherited from 18th-century marine chronometers, where the spring rises perpendicularly around the upper stem of the balance staff. This geometry improves isochronism and reduces friction, qualities that are further enhanced in combination with a tourbillon. Each cylindrical hairspring is shaped by hand at Precision Engineering AG, Moser's sister company, a process that takes ten times longer than producing a conventional flat spring.
The only non-skeletonised element on the dial side is a small domed sub-dial at 2 o'clock in Moser's Funky Blue fumé, carrying the brand's logo in transparent lacquer and Roman numeral decals as a deliberate counterpoint to the mechanical openwork surrounding it. The fully skeletonised, hand-wound HMC 909 calibre comprises 415 components across a 33 mm diameter, runs at 21,600 vib/h, and offers a 90-hour power reserve. The watch is finished on a hand-stitched grey nubuck alligator strap with a titanium pin buckle.
Endeavour Perpetual Calendar Concept Tantalum
At the opposite end of the visual spectrum is the Endeavour Perpetual Calendar Concept Tantalum (ref. 1800-2004), a piece that strips everything away. Limited to 50 pieces, it takes Moser's already minimalist Perpetual Calendar and pushes the Concept series logic further: No logos, no indices, no graduations.
That material is the dense, hard, and ductile tantalum, with a melting point approaching 3,000°C and exceptional resistance to corrosion. When exposed to air, it naturally forms a thin protective oxide layer without tarnishing, and its dark grey hue shifts with bluish reflections depending on the light. Crucially, tantalum is used here not only for the 42 mm case but also for the dial, machined directly from a tantalum plate and given a brushed sunburst pattern with no lacquer, no surface treatment, and no varnish applied over it. The result is a dial that reads as raw and mineral, its reflections varying with the angle of light.
What remains on the dial is pure Moser Perpetual Calendar: an instantaneous jump big date display, a central month hand, small seconds at 6 o'clock, and a power reserve indicator at 9 o'clock showing the HMC 800 movement's minimum seven-day reserve. All adjustments, forwards and backwards, are made via the crown at any time of day. Leaf-shaped steel hands contrast quietly against the tantalum dial. The movement runs at 18,000 vib/h across 294 components, with a double barrel, gold pallet fork and escapement wheel, and Moser's original double hairspring. It wears on a hand-stitched grey nubuck alligator strap with a steel folding clasp.
Streamliner Two Hands Available in 34 mm and 28 mm
Since its 2020 debut, the Streamliner collection has been one of Moser's most commercially and critically successful lines. At Watches and Wonders 2026, the brand extends it in a direction that the industry rarely takes seriously: smaller diameters, without compromise.
Two new Streamliner Two Hands references are presented: a 34.2 mm (ref. 6400-1200) and a 28.3 mm (ref. 6410-1200). Both are steel cased with integrated bracelets that have been redesigned and refined to sit correctly on slimmer wrists. Both are water-resistant to 12 ATM and are fitted with self-winding movements – the HMC 400 in the larger and the HMC 410 in the smaller, each running at 25,200 vib/h with a minimum 60-hour power reserve and an oscillating weight in solid 18-carat red gold. The choice to equip compact watches with mechanical in-house movements rather than downsizing to quartz is a deliberate one, and a relatively rare commitment at this price point.
The dials are the other talking point. Stripped of indices and the Moser logo entirely, they carry a frosted texture produced by a manual engraving process stamped onto brass before a gradient lacquer finish is applied. The 34 mm is offered in Silver fumé; the 28 mm in Burgundy. Depending on the angle, the surface catches and refracts light in a way that reads almost textile. Super-LumiNova-coated hands are the only concession to practical legibility.
Streamliner Pump × Reebok
The fourth release is the Streamliner Pump, a collaboration with Reebok that emerged from Moser's Exploration LAB. The concept is straightforward: The iconic orange inflation button from Reebok's 1989 Pump sneaker has been transposed into a watch-winding mechanism. Pressing the anodised aluminium pusher, which replaces the traditional crown, transmits energy directly to the barrel spring and simultaneously activates the power reserve indicator. A single press delivers more than one hour of reserve. Once fully wound, the pusher can continue to be pressed with no mechanical consequence.
To accommodate this system, Moser completely re-engineered the automatic HMC 500 movement into a manual-winding calibre, the HMC 103, running at 21,600 vib/h with a minimum 74-hour power reserve across 131 components. The partially skeletonised bridges make the mechanism visible through the sapphire caseback.
The case material is equally unconventional: forged quartz fibre, purer and more UV-resistant than glass fibre and, unlike carbon, capable of being coloured. It is cut into segments, placed in a mould, compressed, and combined with injected resin through two curing cycles. The process produces matte cases with a moiré pattern that is unique to each individual piece. Inside sits a titanium sarcophagus that protects the movement and ensures water resistance to 10 ATM.
The watch measures 40 mm in diameter and 11.4 mm thick, with an integrated rubber strap. The lacquered dial — black on ref. 6103-2200, white on ref. 6103-2201 — carries an orange power reserve disc as a nod to the Pump's signature button. Each reference is limited to 250 pieces. As a companion, Moser and Reebok have produced an exclusive co-branded Pump sneaker reserved for Streamliner Pump owners.
