H. Moser & Cie. has never been one to shy away from a bold idea, but its new Pop collection might be the most vibrant expression of the brand since many years. This series of limited edition watches takes the minimal Endeavour platform and completely reimagines it using natural gemstones, turning each piece into a wearable, and highly technical, work of art.
The Pop collection is made up of various Endeavour Small Seconds Concept, Endeavour Tourbillon Concept, and Minute Repeater Tourbillon Concept models, all distinguished by vivid, two-tone dials crafted from precious stones such as Burmese jade, pink opal, lapis lazuli, lemon chrysoprase, turquoise, and coral. The result is a dramatic contrast between Moser’s typically minimalist aesthetic and an unapologetically colourful, maximalist material palette.
There are no indices or logos on the dials, just the natural texture and hue of the stones, and the brand’s signature leaf-shaped hands. The Small Seconds Concept models are housed in 38mm steel cases and run on the automatic HMC 202 calibre with hacking seconds, a bi-directional pawl winding system, and a solid gold rotor. These models are limited to 28 pieces per dial combination.
The Tourbillon Concept editions take things a step further, introducing a one-minute flying tourbillon into a 40mm steel case, powered by the automatic HMC 805 calibre with a skeletonised red gold rotor. Each dial variation is limited to just five pieces. At the top of the series, the Minute Repeater Tourbillon Concept comes in a red gold case and combines both complications, minute repeater and flying tourbillon, on a dial adorned with hand-lacquered and gemstone surfaces. Each of these is a unique piece.
Beyond the technical specs and finishing, what stands out most is how confidently these watches break away from traditional high horology watch design. The dials are vivid and unusual, but thoughtfully paired: jade with pink opal, lapis with lemon chrysoprase, and turquoise with coral. Each pairing balances softness and saturation, structure and chaos. The use of ostrich and alligator leather straps in muted grey tones helps ground the otherwise eye-catching compositions.
This is not the first time Moser has played with colour, but it’s the first time they’ve combined natural stones in this way. It’s also another reminder that for all of its mechanical sophistication, the brand continues to value creativity, humour, and surprise, making the Pop collection less of a gimmick and more of a genuine contribution to modern independent watchmaking.
