Watch Specifications
Elegant Pushers
Here in the silver stainless steel version: The pushers are the direct contact between clockwork and man. The stop function can be started, stopped and reset. The smooth, unscrewed pushers give the watch a fine retro elegance. This is underlined by the high-curved glass, with which the watch slides very gently under cuffs VIEW ON-CHAIN-DPP
The watch is a symbol of innovation and exclusivity — representing eternity. Each purchase includes the certificate of authenticity, two-year standard guarantee, a credential card for the digital product passport (DPP), and the access to a Cardano-based DPP, powered by Tokenance. The lucky buyers will also find, inside the DPP, the opportunity to write an eternal message of love (text-based) to their most loved ones and record it on the Cardano chain. They will also be able to converse with a proprietary AI agent, incarnating Ms. Ada Lovelace.
Caliber C8100
A protective cover shields the anti-reflective sapphire crystal. Once opened, the movement beneath the glass is revealed – the watch comes to life.The C8100 movement is manufactured specially for us by Concepto, according to our high standards of Swiss watchmaking.
It is an automatic movement featuring hours, minutes, and central seconds, a hacking mechanism, Etachron fine adjustment with eccentric regulator, 28,800 vibrations per hour (4 Hz), 25 jewels, and a power reserve of 44 hours.
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. The darker, the brighter
Super-LumiNova is a brand name under which strontium aluminate–based non-radioactive and non-toxic photoluminescent or afterglow pigments for illuminating markings on watch dials, hands and bezels, etc. in the dark are marketed. This technology offers up to ten times higher brightness than previous zinc sulfide-based materials. When the luminescent pigments were stimulated by daylight or artificial light, they give off the light energy in the dark for several hours. This gives the watch extremely good legibility even in the dark. 1

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. 💗
