Introducing the Deco Moon
A watch that recalls the glamour of the golden age—where dress and daring merged in the skies. The Deco Moon is Riley’s first moonphase complication, a square-Roman inspired piece through which elegance meets aviation’s vintage edge. It’s made for those who want a dress watch with a story.
A Statement in Every Detail
Ultra-slim, elegantly curved, and square in form, the Deco Moon is made to sit beautifully on the wrist. Its Moonphase display dominates the dial with grace, framed by bold Roman numerals and a case that bridges classic refinement and modern presence. Designed and hand-built in our Manchester workshop, this is watchmaking with both passion and precision.

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

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:

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.
