  • Ratio watches started in 2017 in Singapore. The premise was simple – to make quality watches with exceptional craftsmanship, materials, and attention to detail rivaling the big watch brands. At a price point that is accessible. The name we chose – RATIO – signifies not just an exceptional price-to-quality ratio but also the fact that different ratios are ubiquitous in horology. Our logo celebrates the most famous of all ratios – pi. At Ratio Watches, we’re passionate about creating timepieces that embody the adventurous spirit of extreme sports enthusiasts. Our journey began with the launch of our first collection, which celebrated the thrilling sport of Freediving. The bold designs of this collection immediately caught the attention of watch enthusiasts worldwide, inspiring us to continue to add more designs to the range. But we’re not content with simply resting on our laurels. At Ratio Watches, we’re constantly pushing the boundaries of watch design, seeking to create innovative and exciting timepieces that capture the essence of the extreme sports we love. See More
