DIVE-WATCH HERITAGE WITH MODERN VERSATILITY

Purpose-built for both adventure and everyday wear, the Baleine blends classic dive-watch heritage with modern versatility and design precision. From open waters to city streets, its 40mm case and 12.1mm slim profile — including a double-domed sapphire crystal — embodies durability, timeless character, and understated confidence. Created for those who value refined engineering with a utilitarian edge.

Automatic movement

This latest generation of the Baleine is powered by the Japanese Miyota Cal. 9039 automatic movement, operating at 28,800 vibrations per hour (vph) with up to 42-hours of power reserve. A robust, no-date caliber chosen for its precision, reliability, and slim construction.

GREAT LEGIBILITY IN ALL SITUATIONS

The Baleine ensures exceptional legibility in any situation. Hands, applied dial indices—together with the 60-minute bezel scale—are filled with Swiss Grade X1 Super-LumiNova®, providing a powerful and enduring glow for night or underwater visibility.

DESIGNED AND ENGINEERED IN STOCKHOLM, ASSEMBLED IN GERMANY

Each Nezumi watch is designed and engineered from the ground up by David Campo at our Stockholm headquarters. Aside from the movement, every component, from the case, dial, hands and more, are purposefully crafted with precision. Assembly, testing, and final inspection take place in Germany, adhering to the same rigorous standards required for “Made in Germany” certification. The result is a timepiece built to last.
