For over 170 years, Ulysse Nardin has been creating some of the most reliable marine chronometers in existence. With this latest addition to the Marine Diver collection, the Manufacture in Le Locle firmly establishes its reputation as a cutting-edge watchmaker.

Resolutely anchored in aquatic sports, the brand new Blue Ocean is designed to tackle extreme conditions. It perfectly combines its dual function as a diving instrument and beautiful watchmaking piece.

Its stainless-steel case has been specially treated with a sophisticated vulcanisation process giving it a blue rubber coating with a remarkable appearance and a truly comfortable feel.  Its exhibition case-back reveals the self-winding movement also blued.

Fitted with a unidirectional rotating bezel and screwed crown, its individually-numbered case is water-resistant to 200 metres. This edition is limited to 1846 pieces, each individually numbered on the side of the case.
