The Longines HydroConquest collection represents a perfect marriage of high-performance engineering and sophisticated style. Since 1974, we have admired how this series balances the demands of professional diving with a refined aesthetic that suits any occasion. This 41mm model features a striking sunray black dial protected by anti-reflective sapphire crystal and a durable ceramic bezel. Powered by the precise L888 automatic movement, it offers 30 bar water resistance and Swiss Super-LumiNova® for exceptional clarity.
