nown by the Latin name Oceanus Procellarum, this is actually a lunar mare located on the western edge of the near side of the moon. Meaning Ocean of Storms, it is the biggest mare or “sea” on the moon, spanning more than 2,500 kilometres from north to south and covering around 2 million square kilometres. The new Bioceramic Scuba Fifty Fathoms Ocean of Storms, however, is nowhere near that big. In fact, it has exactly the same dimensions and features as Arctic Ocean, Pacific Ocean, Atlantic Ocean, Indian Ocean, and Antarctic Ocean.

A non-limited model, Ocean of Storms, comes in a black color inspired by the new moon (also known as the Black Moon). Just like the other five Bioceramic Scuba Fifty Fathoms, Ocean of Storms has a Swatch mechanical movement, Sistem51, the first and only mechanical movement whose production is entirely automated. This mechanism, made up of just 51 parts - including one central screw, is anti-magnetic, thanks to its Nivachron^TM hairspring and has a 90-hour power reserve. In 2013, Sistem51 revolutionised the world of automatic watches with its visible movement: the front tells the time, the back tells the story.

Ocean of Storms has been given its own nudibranch (scientific name: Nudibranchia), Okenia Luna. It is featured in a digital print on the movement’s rotor, the part that allows the watch to recharge automatically with a simple movement of the wrist. The full moon zoomed in on the Ocean of Storms is also digitally imprinted on the oscillating weight.

Ocean of Storms, like Arctic Ocean, Pacific Ocean, Atlantic Ocean, Indian Ocean, and Antarctic Ocean, is water resistant in deep waters, down to 91 meters. This is another nod to Blancpain: the name Fifty Fathoms refers to the fathom – historically the maritime measure of depth in the English-speaking world – fifty fathoms equaling 91 meters (or 300 feet).

In the same spirit as the other five models in the collection, Ocean of Storms is made of Bioceramic. This unique material is patented by Swatch and made of two-thirds ceramic and one-third biosourced material derived from castor oil. As an expression of commitment to ocean preservation, the NATO straps are made from recycled fishing nets.

The shared Blancpain X Swatch logos can be found on the black sunray-finish dial and the crown. The word “Swatch” is also inscribed on the case, just as “Blancpain” is inscribed on the original Fifty Fathoms watches. The back of the watch features inspirational inscriptions like Passion for Diving – Licence to Explore – Ocean Breath – Protect What You Love – Immerse Yourself.

Ocean of Storms will be available worldwide, as with the five watches in the Bioceramic Scuba Fifty Fathoms Collection, and are limited to one watch per person, per store and per day.
