The ultimate sophistication in diving equipment, both aesthetically and technically, the Tissot Seastar 1000 Chronograph embodies style and performance without compromise. Perfectly reliable up to a pressure of 30 bar (300m), it is proof that an underwater sports watch and a chronograph can be reconciled in one object. The diving theme is omnipresent with elements such as a unidirectional aluminum bezel, luminescent hands and indexes. Finally, the Tissot Seastar 1000 collection offers a multitude of choices of compatible straps.
