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.

Long-time Triwa user here, and I am always impressed by how the brand blends timeless design with modern details. The Koster Rubber feels genuinely high quality from the moment you pick it up. It is comfortable, well made and has that clean, confident look that works for both everyday wear and more dressed occasions.

Just received my green Koster on green rubber. Watch feels great in shape and size and the dial is awesome. The rubber strap is extremely soft and comfortable and the clasp feels really solid. 10/10

Just received it, looks and feels nice. The dial pattern is subtle which I think gives it a clean look IRL.
