Note: All of our watches are built and shipped from the UK, and so are subject to a tariff of 10% on shipments to the USA. We pay this tariff as we ship, so US customers won’t receive any unexpected fees on delivery. In other words, the price you see and pay at checkout is the price you pay for the watch, nothing more.
Jerrie Cobb Solar ‒ JC01
A tribute to courage, a companion powered by light. The JC01 honours Jerrie Cobb — pioneer aviator, record-breaker, and one of the original Gemini astronaut trainees — with a watch that is as forward-looking as her legacy.
Powered by the Stars
Harnessing the sun’s energy, the JC01 uses a Seiko AS01 solar movement, converting daylight into precision, with a power reserve of approximately four months once fully charged. No battery changes, just perpetual motion.

Why the JC01 Resonates
-
Honouring a Pioneer — Jerrie Cobb’s achievements in aviation and space-flight broke barriers. This watch captures that spirit: bold, uncompromised, visionary.

Light-Powered Precision — No winding, no battery changes. Just let it see daylight and it keeps going — a timepiece that works in harmony with nature.
-
Wearable Grace — At 38 mm by 9 mm, it combines presence with subtlety — equally at home under a shirt cuff or out during the day.
-
Personality Through Colour — With a dozen striking colourways, the JC01 isn’t just about telling time — it’s about expressing identity.
The Riley Promise
Hand-built in the UK, the JC01 arrives with fast shipping and a 30-day return policy. Price shown covers global delivery (including the U.S.), so what you see is what you pay — no surprises.
Own a Part of the Skies
Our JC01 offers a rare union: heritage, sustainability, design. More than a watch — it’s a beacon of inspiration, proof that a legacy can shine as bright as the stars.
SHIPPING + RETURNS
THE RATHER IMPORTANT BITS
This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.
SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.
Some are brilliant at international shipping, others prefer to keep things closer to home.
At checkout, you'll see exactly where this particular brand can send your goodies.
We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!
RETURNS
You have 14 days to return items.
Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!
🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.
Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!
The brands we work with all have a chat option, and they love to chat!
PAYMENT
We're frightfully modern and accept all the usual suspects:
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay
SECURE AS HOUSES
Everything's properly encrypted and secure - your details are safer than the Crown Jewels!
All prices in lovely British pounds £ GBP, though international chaps will see converted prices.
Any payment pickle? We're here to help sort things out! Contact us

We are Sostter
Sostter began, as all good ideas do, with a lively conversation and a shared sense of frustration. Why had the world of independent design become so serious, so samey, so… beige? Where was the spark, the imagination, the sheer joy of discovering something that made you stop and stare?
We dreamt of a marketplace that celebrated difference — where curious minds could explore a world of independent brands, design-led makers, and thoughtful artisans. A space that felt exciting, human, and beautifully imperfect.
Today, Sostter brings together remarkable people and their creations — from London to Lausanne, Brooklyn to Berlin — uniting makers and discoverers through craftsmanship, creativity, and conscience. Every object tells a story, and every purchase supports an independent brand doing things differently.
This is just the beginning. But enough about us — step inside, explore our world, and see what catches your imagination.
Giving Back
We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.
