This watch was designed in partnership with a leading Swiss design studio especially for researchers and people who delight in the wonders of the deep blue sea. The soft silicone watch strap has a comfortable fit. The durable case is protected by sapphire crystal, the entire structure is resistant to damage and scratches, large luminous hands are visible underwater and in the dark, and the unidirectional bezel is designed so that you can easily time the dive, even with gloves on. The watch case comes in steel or black with an ion coating, which offers resistance to damage and scratches. The dial is available in blue, gray or deep blue — this design is inspired by the play of iridescent colours in the depths of Lake Baikal.
