Stone dials pushed their way into the watchmaking zeitgeist in 2025 and their momentum hasn’t dropped off in 2026. One of the reasons for that is there’s such a huge variety of minerals in the world that there’s an almost inexhaustible well of inspiration for watchmakers. While there are staples like tiger’s eye or malachite, there are also significantly nicher stones that create a heightened sense of individuality when watchmakers use them. Case in point, the new Chronoswiss Small Second Jasper and Small Second Serpentine.
Jumping straight to the dials, they are each produced from their eponymous semi-precious stone. The Jasper edition is made from a golden brown jasper sourced from Idar-Oberstein, Germany that has a subtly shifting gradient across its surface punctuated by darker veins. In contrast, the Serpentine edition is a vivid and vibrant green with all manner of hues and shades on display that together create a scale-like appearance, which is what gives the stone its name.
For timekeeping, they feature feuille (leaf shaped) hour and minute hands filled with Super-LumiNova for low light legibility. The seconds are displayed by a small seconds subdial at 9 o’clock finished with a radial, fluted guilloché. They also use stylised Arabic numerals across the timing scales that are like exaggerated Breguet numerals.
Both versions of the watch measure 40mm in diameter with an 11.5mm thickness that puts them on the larger end of the dress watch spectrum. That sizing makes sense because you want to show off the intricate textures of the natural stone dials. However, while the two watches are the same size, they’re made from different materials. The Small Second Jasper is full stainless steel while the Serpentine is bi-metallic, featuring a steel case body and lugs but a red gold bezel and crown.
Inside, they both use the Chronoswiss calibre C.6000 with 55-hour power reserve and 4 Hz frequency. It’s visible through the exhibition caseback where you can see its openworked tungsten rotor and immaculate finishing. The Côtes de Genève in arabesque are particularly attractive – arabesque meaning they radiate or curve outwards from a central point rather than the normal parallel stripes.
For pricing, the Chronoswiss Small Second Jasper is £12,200 and the Serpentine is £17,900 due to the gold elements across the case. Each is limited to 50 pieces, making for a total edition of 100 watches. This is a case where although the name tells you everything you need to know about the watch, it rewards careful study to appreciate every detail from the coin-edge bezel to the stone dial, the movement and timing scales. It’s also cool to see one of Chronoswiss’ smaller collections expand with new versions that embrace stone dials for the first time.
