STRAP SELECTION
Discover our exclusive selection of watch straps that combine maximum comfort and individual design. Choose between a handcrafted Barenia leather strap - available in the finest blue, warm cognac, elegant black or seductive dark chocolate brown - and an elegant gold-plated stainless steel Milanese. Each strap is crafted with the utmost care and makes a stylish statement on your wrist. Elegant Pushers
Here in the gold-plated 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 Engraving

It is a automatic movement with hours, minutes and sweep second. Second stop device, eccentric fine adjustment Etachron, 28,800 vibrations per hour, 4 Hz, 25 jewels.
Gold-plated 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. The golden keys of Les Clefs d'Or

Christmas came early! 🌟
We had the pleasure of customising a Züri-Date for the 10th anniversary of a Zurich-based company(and let us tell you, it was a success!)
The whole team put their creativity and dedication into it, and together with the CEOs, we created something very special to celebrate this milestone.
We couldn’t be happier to have made this evening memorable and to be part of their journey.
Maybe you’re next? 😉

Some watches tell the time. Others make it shine.
Perhaps that is precisely why the DJ duo Doppelgänger love the Pillow Ghost so much. Amid the beats, movement and people who want to lose track of time for a few hours, this watch feels remarkably at home. It dances along. On a wrist that plays music, follows rhythms and shapes the night. And while the lights flicker around it, its own glow gives time both clarity and meaning.
There is something lovely about that thought. A watch that comes most vividly to life in the very place where people would rather forget what time it is.
Pillow Ghost 👻
Because the Ghost has a special relationship with darkness. As daylight fades, its luminous dial comes to the fore. What is an exceptional piece of design by day becomes a small spectacle of light and time at night. The watch changes its appearance without losing its character. It becomes visible as so much around it disappears from view.

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. ❤️
