Pelagos UltraThe new Pelagos Ultra was built for deep sea diving with a 43mm titanium case to meet a staggering depth rating of 1,000 meters. Luminescence has been thought through to increase visibility with two different colors: blue and green. The bracelet has also been completely redesigned with this deep diving brief in mind. The newly redesigned case makes use of both grade 2 and grade 5 titanium and includes a compact helium escape valve for fluid egress
