The new Pelagos Ultra was built for deep-sea diving with a 43mm titanium case to meet a staggering depth rating of 1,000 metres. Luminescence has been thought through to increase visibility with two different colours: blue and green. The bracelet has also been completely redesigned with this deep-diving brief in mind. METAS Master Chronometer certification is comprehensive and covers the main functional characteristics of a watch including precision, resistance to magnetic fields, waterproofness and power reserve. Its standards are incredibly high, starting with precision.
