Blue Sea
A symbol of the vigour of youth, this powerful timepiece showcases Ulysse Nardin’s constant advances in watchmaking technology. Its stainless-steel case, 45.8 millimetres in diameter, 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. The non-moving metal parts of the movement have been treated with a stainless blue titanium based alloy (ion sputtering process). Where necessary, the metal parts have been reworked to accommodate the blue coating, the thickness of which is 1 micron with a hardness of 1500 HV.
