TISSOT RockWatch: Would you dare wear a watch with a stone case?

Tissot RockWatch
Tissot brings back the RockWatch, a bold design from the ’80s, in a collector’s edition limited to just 999 pieces.

Tissot is a historic watchmaker that has never shied away from challenges. From the plastic-cased watches of the ’70s (Astrolon) to the first touch-screen models in 1999 (T-Touch), the brand has always loved to experiment where others play it safe. Perhaps its most audacious creation came in 1985: the Tissot RockWatch, a timepiece with a case carved from Swiss granite. Four decades later, Tissot revisits that daring idea, this time with a limited run of 999 units, breathing new life into one of the most unexpected ideas in watchmaking history.

The new Tissot RockWatch is made from granite sourced from the Jungfrau, one of the Alps’ most emblematic peaks. After centuries buried deep in the mountain, this rock has been transformed into 38mm cases that feel as much like sculptural objects as wristwatches. As I’ve noted before, watch sizes are trending smaller, with both men and women gravitating toward the 38–40mm range. In this case, 38 mm hits the sweet spot for those who want a watch with character yet one that remains highly wearable.

What we love

The black leather strap brings both contrast and comfort, while the anti-reflective sapphire crystal is a welcome upgrade over the mineral glass of the original model. The crystal flows smoothly into the case’s pebble-like curves, giving it a natural organic feel. The slim nickel-plated hands are a thoughtful choice too, lending a more refined, timeless look compared to the colorful, playful colorful hands of the first RockWatch.

Above all, though, what makes this watch stand out is its identity. In a sea of safe design choices and lookalike models, Tissot has created something genuinely different. There’s something almost romantic about strapping a piece of raw, natural stone to your wrist. Even the presentation box—shaped like a solid granite block—underscores this connection to nature and to the Swiss roots of the watch.

What we would change

The RockWatch houses a quartz movement. It’s practical and reliable, yes, but some collectors will no doubt wish it had a mechanical caliber to match the exclusivity of a 999-piece limited edition. An automatic movement might have felt more in tune with the spirit of the watch, but given the weight of the case, I suspect Tissot opted for quartz to keep it wearable.

Another point worth mentioning is the strict monochrome aesthetic. It is minimalism taken to the extreme—an elegant restraint for some, but perhaps too austere for others. The original RockWatch, after all, had colorful hands inspired by Swiss hiking trails: a yellow hour hand and red seconds hand that popped against the grey stone.

The original Tissot RockWatch boasted two colorful hands set against its stone dial.

The modern version plays it neutral and subdued. Since I haven’t handled it in person, I can’t yet say how the hands perform on the wrist.

Why it’s worth considering

The Tissot RockWatch is back, and it’s every bit as daring as it was 40 years ago. It’s not a watch for everyone—and that’s precisely the point. This is for the eclectic crowd, for those who value history, originality, and the authenticity of wearing a fragment of Swiss granite on the wrist. For all its quirks, the RockWatch remains a fascinating proposition: bold design infused with genuine Alpine heritage. Price: €1,095.

And as you’ll see in the video below, the process of shaping that granite case is just as captivating as the finished product.
