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 stainless steel Milanese. Each strap is crafted with the utmost care and makes a stylish statement on your wrist. 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 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.
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

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. 💗

ZFF Award Night 2026 — it’s a wrap. 🎬✨🪩
Dancing with family. Laughing with friends. Watching great movies. Meeting old friends and new faces.
And then — seeing the legend Andy Garcia, both in real life and on the big screen. ✨
A night full of films, laughter, music, good people and a little bit of magic.
What more could you wish for in one night?
Until next year, ZFF. 👀👋🏻

3…2…1… ACTION! - On the court 🎬🎾
We were proud to sponsor Tennis tournament of the Zurich Summit 2026 and celebrate the winners with 2x Swiss Tennis Rallymaster.
This year, the tournament was part of the vibrant atmosphere surrounding the Zurich Summit, a prestigious two-day boutique conference bringing together leading filmmakers, executives, agents, entrepreneurs and investors from film, entertainment and technology.
With a unique focus on connecting the European and US markets, the Zurich Summit creates opportunities for cross-border collaboration, inspiring conversations and new ideas.
From the tennis court to the world of film, creativity and technology — we love seeing different worlds come together in Zurich. I

Can’t wait for all the amazing movies, people and moments over the next two weeks.
See you there or in the shop?
Now even closer to the main venue! #mauricedemauriac #ZFF #russellcrowe #rallymaster #zurich
Homo Faber — An Island of Light. ✨
An entire island celebrating the people who make things by hand.
One of the most beautiful exhibitions we have seen , because at its heart is an idea we deeply believe in: craftsmanship matters.
Every room is another universe. Different materials, different traditions, different hands, but always the same obsession with detail, precision and creating something that lasts.
It felt very close to what we believe:
Our watches are not made to simply tell time. They are objects shaped by people, attention and countless small details. From the first sketch to the final hand finishing, it is the human touch that makes a watch feel like more than an object.
Homo Faber celebrates the makers.
We celebrate them too.
Because in a world of mass production, there is something quietly powerful about making fewer things — and making them well.
If you are in Venice, go. If you’re not — perhaps this is a good reason to come. 🇮🇹

72 hours in Venice 🇮🇹
Couldn’t fit more food or drinks into these 3 days…
We were just talking about how lucky we are that we get to travel together as siblings, and all three of us couldn’t be more grateful for everything we get to experience together. Sharing it makes everything so much more fun and meaningful. Wouldn’t be the same otherwise. ❤️
If you need some Venice inspiration, hit us up haha - we got you!!
Walked 15k, ate and drank like kings & queens all day long!
See you soon again, Venice! 🤍 #mauricedemauriac #venice #homofaber #italy #watches
When Russell invites you to the Venice Film Festival, you arrive in style. ✨
What an honor and privilege to be part of the chosen small crew witnessing the premiere of Russell’s heart project: WHAT LOVE BUILDS ❤️
His biography, documenting 47 years of making music and the incredible journey behind it, was brought to life on the big screen in the sold-out Sala Grande at the Venice Film Festival — and honestly, it was simply out of this world.
From Zurich, to Australia, and now to Venice… we couldn’t be more proud to have been a small part of Russell’s journey over the past year.
What a year it has been for us. ❤️
Thank you so much, Russell. We truly appreciate it all and never take any of these incredible moments for granted.
Here’s to music, friendship, unforgettable experiences, and a year we will never forget. 🥂✨
