The ocean, which covers more than two-thirds of the earth's surface, is a source of precious resources and inspiration.

Swiss luxury watchmaker Blancpain, a long-time supporter of ocean exploration and preservation, launched a 250-piece limited edition in Shanghai in November.

With an entirely blue ceramic case, the Fifty Fathoms Bathyscaphe Flyback Chronograph Blancpain Ocean Commitment II, also known as BOC II, is part of the brand's commitment to the ocean.

For every watch sold, 1,000 euros ($1,052) will go toward scientific expeditions.

A total amount of 250,000 euros will be part of the brand's support of ocean exploration.

Chinese actor Wu Xiubo became the first Chinese buyer of the new watch.

It is the second of a series of limited editions dedicated to the ocean.
