Become one with the ocean.


The original meaning of CREST is the top of the mountain, which is also the peak of the wave. We want to level up the industry and arouse everyone’s enthusiasm for the sea just like the power of the wave.​

We boldly break the past product design thinking and develop innovative precision structure.  We focus on high performance, lightweight and aesthetic style for product design. All the product are based on high quality and high specifications from design, manufacturing, and testing to shipping. Each product is subjected to strict CE certification, requiring detailed inspection and a complete record of the whole process involved.​

Our core team has many years of professional experience and has participated in the development design of the world’s top brand of diving regulators. We create each product with care to ensure the best performance, and hope to bring new experiences to the divers.

We believe that if more people love the ocean, the future of the ocean will be clearer.
