We believe in a life lived, not scrolled.

The Koster was born on the Swedish West Coast. A place where granite meets the deep blue, and the weather decides your schedule. It is built for the distinct rhythm of a life in motion.

From the morning plunge to the boardroom focus. From exploring new islands by boat with friends to dinner as the sun sets. Waking up the next day to waves crashing in a new place, clearing the inbox over morning coffee, then taking the scenic route to your lunch meeting.

In a world of constant notifications, the Koster is your analog anchor. A reminder to look up, disconnect from the feed, and reconnect with the rush of real life.

Triwa Koster. Swedish Soul. Ocean Heart. Ready for anything.

Inte så plastig

Förväntade mig en lite mer plastig känsla, men tavlan är matt och ser lite mer dyr ut än väntat.

Swedish style

Clean, functional, and well made. Love the concept.

I really like this watch. The 39mm case is the perfect size, and the recycled plastic dial looks awesome. My favorite feature, however, is the GMT complication. Great stuff!

Nice that they managed to make the watch look and feel high quality IRL. First thought it might look a bit cheap IRL due to the plastic dial, but it dosent.

THE STATEMENT

The dial is crafted from recycled Ocean-bound Plastic, featuring a rich 3D wave texture that captures the deep, restless motion of the sea. It serves as a grounding force, a piece of raw nature on your wrist that brings clarity to high-pressure moments.

Dark, distinct, and sophisticated, it looks as natural on the boat in the archipelago as it does at the business lunch. It’s a reminder that you can lead with style and substance.

THE CONTRAST

True performance is about adaptability. We sculpted the 39mm stainless steel case to bridge the gap between the archipelago and the conference room.

The brushed steel echoes the rugged strength of Swedish granite rocks, while the polished accents provide the sharp elegance required for the street. It is built to endure the elements, but designed to command the room.

THE PRECENSE

Your phone vibrates. The ocean crashes. We know which one we prefer. In a high-speed world, true luxury is focus. With 20 ATM water resistance and a precise GMT movement, the Koster gives you total control over your time.

It is built to handle the pressure whether that’s deep underwater or in a high-stakes meeting. No notifications, no noise, just you, on time and in the moment.
