The unidirectional bezel with domed black ceramic insert is angled towards the dial, making it easy to use even with diving gloves. Absorbing up to 97% of light, the absolute black dial ensures optimal readability underwater, not to mention the hour-markers formed by luminescent block-shaped appliques.

Since 2020, Blancpain has supported this programme by the Sulubaaï Environmental Foundation, a collaborative initiative aimed at the sustainable management of marine resources. The programme focuses on creating a network of marine protected areas (MPAs) in partnership with local communities around Pangatalan Island and in Shark Fin Bay, Palawan, Philippines. The key principles of the Sea Academy are protection, restoration, education, and replication.

Since 2023, Blancpain has funded the construction of the Blancpain x Sulubaaï Marine Research Center in the village of Sandoval. This centre, strategically located near the main research areas and the five MPAs established in Shark Fin Bay with Blancpain's support, aims to enhance the study, restoration, and protection of these marine ecosystems.

The operations and activities of the Blancpain x Sulubaaï Marine Research Center will be supported by the sales of the limited edition BOC IV.

More Than Just a Timepiece

Each of the 100 timepieces comes with its Pelicase™ box, a donation certificate, and a special edition photograph in a series of 100 prints, numbered to match the watch's serial number.

Signed by photographer Laurent Ballesta, the image is part of his award-winning series from the 2023 Wildlife Photographer of the Year grand prize. It depicts a horseshoe crab in its natural habitat around Pangatalan Island in Shark Fin Bay. This prehistoric animal, whose morphology has remained virtually unchanged for 150 million years, is now threatened with extinction. The marine protected areas created by the Sea Academy programme offer it a safe haven.
