Seestern S406 — Precision Crafted for the Deep

Born from the legacy of Sugess Watch Company, the Seestern S406 Sub300T is a masterclass in mechanical watchmaking. Whether you're exploring the ocean's depths or commanding a boardroom, this timepiece carries the quiet confidence of a watch built without compromise.

With 200m water resistance and a secure screw crown, this watch is ready for every adventure you are.

Available in a curated palette of bold and understated tones — from classic Black and Silver to vibrant Army, Dark Blue, Light Blue, Yellow, Orange, and Aventurine — the S406 lets you express your style without saying a word.
