NORDIC MARINE INSTRUMENTS: Østersøen - Blue Mother of Pearl

NORDIC MARINE INSTRUMENTS Østersøen - Blue Mother of Pearl

Østersøen is a Scandinavian automatic dive watch inspired by the Baltic Sea. This version features a natural blue mother-of-pearl dial, giving every watch a subtly individual pattern and play of light.

The clean, date-free layout is complemented by diamond-cut hands and indices and Swiss Super-LumiNova BGW9 for clear legibility in low light. A marine-grade stainless-steel case, sapphire crystal and 200-metre water resistance make Østersøen suitable for both everyday wear and demanding use.
