Screw-down pushers
Screw-down pushers confer an additional mechanical aspect to our watches. In order to operate the stopwatch function, you have to first unscrew the collar and, then, close it again after stopping it. Chrono , screw-down pushers, caseback
Our display back case uses a blue anti-reflective sapphire crystal and thus allow for an unobstructed view of the pulsating calibre. One has the feeling that the soul of the mechanical automatic movement can both be felt and seen. The watch is alive. Together with the possibility of the custom labelled rotor, each watch becomes a truly personal gift – even to oneself. ETA 7750 Movement
After the takeover by ETA, the Valjoux 7750 was re-named the calibre ETA 7750. This is quite possibly the most successful automatic chronograph movement of all time. The calibre stands out due to its high degree of accuracy and robustness. It has 25 stones, a ball bearing mounted rotor and a uni-directional winding mechanism. The 7750 has a 1/8-second counter, a 30-minute counter, a 12-hour counter, 28,800 half oscillations per minute and has a power reserve of ca. 44 hours. The loss of accuracy is 1-6 seconds per day. Movement revisions are recommended every 3 to 8 years-TOP Execution

Stainless Steel
Not all steels are created equal. We use 316L stainless steel; one of the hardest premium steels in the world. In addition to its hardness and resistance, this high-quality steel stands out because of its finish as well as it very fine silver hue. 316L steel has a significantly lower nickel emission than, for instance, 904L steel, which is also a high-strength steel alloy. This is, for us, a reason to favour 316L stainless steel. 1

Modern
Every company has the mystique of its first employee, its first premises, its first product. The Chrono Modern is the founding mystique that has become a watch. It was the first "real" Maurice de Mauriac. What was revolutionary at the time was the dial designed by Daniel Dreifuss, which we now call the 0510 dial. The numbers from 0 to 55, rather than 1 to 12, indicated the time. The minutes are more important than the hours. An expression of the agility of its wearers. Since women also love this potent statement of time on their arms.
Something new is coming 👻 31 Ocotober 👻

Is there a better watch review as from Russell Crowe himself?
We don’t think so. Enjoy @russellcrowe talking about our newest Rallymaster Swiss Tennis in collaboration with @swiss_tennis - design by @carltondewoody
Happy Sunday FAM ❤️

Oh my god, moving was a huge step for us! ❤️
Taking over our dad’s legacy has been one of the most beautiful gifts we could have received. And getting to do it together, as siblings, makes it even more special.
Wouldn’t be the same without our young, passionate team. So much love for what we do and for the people we do it with. ❤️

Our ZÜRI-DATE BRONZE PINK is a perfect fit for these autum days. The bronze has the warmth of fall, and the pink has the playfulness of summer. It’s a combination you might not necessarily expect. But as a family, we’ve never been particularly good at doing only what’s expected.
The best thing about bronze, anyway, is that it doesn’t care what it once looked like. It changes—with every day you wear it, in response to your skin, the weather, and your habits. It develops a patina that no one can predict. After a few months, your ZÜRI-DATE will look different from the one in the studio—and different from any other. Because by then, it will have become a part of you.

Indian Summer in Zurich 🍁💗
Sometimes all it takes is a sunny October Sunday to bring back a taste of summer. The family gets together, friends join in, jackets stay unbuttoned, and a short walk turns into an entire afternoon. One of those moments you’d love to hold onto forever.
We spent these last warm hours with our ZÜRI-DATE BRONZE PINK—a watch that tells a little more of your story with each passing day. With bronze that changes over time and a shade of pink that refuses to let summer go.

In pink and ready for a ride 💗🏍️
Our Züri-Date Pink, inspired by Zurich’s tram No. 10, now in full bronze and ready to hit the road.
And while we’re out riding, we ride for a reason. Every October, for every pink watch we sell, we donate to @krebsliga in support of Breast Cancer Awareness Month
Good rides with pink vibes for a good cause. 💗
