Official description

Combining performance and style, HydroConquest watches are designed for those who love pushing back boundaries and exploring new horizons.

This 43 mm-diameter model houses the exclusive Longines GMT calibre L844.5, equipped with a silicon balance-spring and innovative components in non-magnetic materials. This movement's resistance to magnetic fields is more than ten times greater than the ISO 764 reference standard. It boasts extreme precision and a power reserve of up to 72 hours.

A black sunray dial, unidirectional rotating bezel in black ceramic, water resistance to 30 bar (300metres) and screw-in crown and screw- down case back are the signature features of this watch inspired by the world of water sports. The model comes with a stainless steel or black rubber strap with double-safety folding clasp with micro-adjustment.
