Chronoswiss Goes Stone: The Small Second Jasper and Serpentine Are the Brand's Most Tactile Dials Yet

Chronoswiss just dropped two new references in its Small Second collection, and they're worth your attention. The Small Second Jasper and Small Second Serpentine are the first watches in the brand's Modern Mechanical era to use natural stone dials. That's not a marketing footnote - it's a genuine first for this chapter of the brand's story.

Each variant is a limited edition of 50 pieces. The case is the same 40 x 50 x 11.5mm tonneau shape introduced in 2025, so the proportions are already familiar if you've been watching the Small Second line develop. What's new is entirely on the dial side.

What's Actually New Here

Stone dials aren't a novelty in watchmaking broadly, but they're a debut for Chronoswiss. The Jasper reference uses red jasper, a naturally opaque stone with the kind of earthy, mottled character that photographs well but looks even better in hand. The Serpentine uses - you guessed it - serpentine, a green-toned stone that has a slightly more muted, mineral quality to it.

Both dials keep the layout simple. The small seconds sits at 6 o'clock, which is a nod to the regulator DNA the brand has carried since Gerd Lang put the first serially produced regulator wristwatch on the market in 1987. No clutter, no extra complications. Just the stone doing its thing.

The Case and Movement

The 40 x 50mm case size is on the larger side for a dress-adjacent piece, but the tonneau shape distributes that footprint well on the wrist. At 11.5mm thick, it's not going to disappear under a shirt cuff, but it's not a chunky sport watch either. It sits somewhere in the dressed-up-casual territory that Chronoswiss has been pushing under Oliver Ebstein's direction.

Inside is the caliber C.6000. Chronoswiss hasn't changed the movement for these stone editions - they're dial-forward releases, and the brand is honest about that. The C.6000 is a solid, in-house-finished movement that suits the character of the watch without needing to be the headline act.

Who This Is For

If you're already a Chronoswiss follower who appreciates the brand's shift toward bold, material-led dial work, this is a natural next step. The stone dials are a more grounded, earthy direction compared to some of the vivid lacquer and enamel work the brand has done recently - so in a way, this might actually appeal to collectors who found the earlier Modern Mechanical pieces a bit loud.

You're also buying into scarcity. Fifty pieces per reference is genuinely limited. This isn't one of those "limited editions" that runs to 500 or 1,000. If you want one, you'll need to move relatively quickly.

• Jasper: Red-toned, opaque, earthy character - the warmer of the two options
• Serpentine: Green-toned, slightly more muted and mineral in appearance
• Both: 50-piece limited runs, small seconds at 6 o'clock, caliber C.6000
• Case: Same tonneau introduced in 2025 - proven fit and proportions
• Significance: First stone dials in Chronoswiss's Modern Mechanical era

How It Compares

Stone dials exist across price brackets right now, from entry-level fashion brands to high horology maisons charging five figures for a sliver of malachite. Chronoswiss is positioning these somewhere in the mid-luxury space, which is where the brand has planted its flag under Ebstein. The honest competition isn't a Piaget Lapis - it's other independent and semi-independent brands doing material-first limited editions at a similar price point.

The tonneau case is a differentiator. Most stone-dial watches default to round cases because they're easier to produce. The shaped case here adds visual interest without being gimmicky, and it connects the Small Second to the brand's broader aesthetic language.

Chronoswiss is building a consistent visual identity one limited edition at a time, and the Small Second Stone Collection fits that strategy cleanly. Whether you're drawn to the Jasper or the Serpentine will come down to personal taste in color - but either way, 50 pieces means the decision shouldn't wait too long.
