Isotope Watches have been a unique icon of the British watch industry resurgence. Creating some of the most original designs at a high level of quality and precision.
Founding Isotope in 2016, the hsuband and wife team of José and Joana set out to create compelling designs at affordable prices that push the boundaries of watchmaking. Almost a decade later and Isotope is an integral part of the British watch industry and an invaluable member of the Alliance of British Watch and Clock Makers.
As is customary for Founders' Friday, I gave José the same set of 15 questions to answer. So, let's hear from one of Britain's most well-loved creative watch designers.
15 Questions with José Miranda
Q1. What was the first watch you ever loved, and did it influence your taste or design philosophy?
The Breitling Jupiter Pilot Réveil. It was the first watch I bought with my first salary. I loved it 30 years ago and I still love it today.
Q2. How did you begin you career in the watch industry?
By curiosity rather than strategy. I wanted a Gérald Genta jumping hour but it was far too expensive. My wife asked, “Why don’t you make your own?” So I did. It was meant to be a one-off. People asked for more. Ten years later, here we are.
Q3. Do you remember the exact moment you decided to turn your idea into a real brand? What tipped you over the edge?
Once people connected with our vision through the Rider Jumping Hour, it became obvious we had to continue. Then came a diver. Then another watch. And it kept going.
Q4. Which other founders or designers have inspired you most in your career?
Too many. I’m obsessed with design, architecture, and art. Gérald Genta and Max Bill are essential references. One introduced me to my favourite complication, the jumping hour. The other connects deeply to my history through his kitchen clock.
Q5. What’s something unexpected that you learned about the manufacturing of watches?
How fragile the supply chain is. Precision doesn’t guarantee simplicity.
Q6. What makes a watch feel “right” the moment you put it on?
Balance. If it disappears on the wrist and others respond to it instinctively, the design worked.
Q7. Where does a new watch design usually begin for you?
With a name, a motif, an artwork, or a moment. Not a sketch. The sketch comes later, once the idea deserves to become a watch.
Q8. What’s a design detail on your watches that people might miss but you’re most proud of?
How light and curvature are controlled. We don’t chase ultra-thinness, but memorability depends on those details.
Q9. What has been the biggest challenge you have faced as you grow your brand?
Scaling without losing freedom or personality.
Q10. What excites you most about the future of the watch industry?
Small brands being bold again, without asking for permission.
Rapid Fire!
Q11. One watch brand (past or present) you deeply respect?
Urwerk.
Q12. One non-watch brand that inspires you?
Porsche.
Q13. Mechanical, quartz, or both — and why?
Both. The right movement depends on the idea, not ideology.
Q14. Favourite complication (even if you rarely use it)?
Jumping hour. Pure mechanical theatre.
Q15. Best piece of advice you ever received in the watch industry?
From Yvan Arpa: “When you think the watch is ready, think again.”
