The first collection we launched was to celebrate the extreme sport of Freediving. With bold designs, this collection was a hit with watch enthusiasts, and we subsequently added more designs to this collection with more in the pipeline.All RATIO watches are made with 316L stainless steel, feature extremely reliable Japanese movements (Seiko or Miyota), have sapphire crystals, strong Japanese lume and are at least 200m water resistant. Instead of spending big amounts on marketing we decided to make a quality product and pass the savings on to our customers by pricing our watches reasonably.
