The Longines HydroConquest GMT [L3.790.4.66.6] represents a sophisticated blend of diving capability and dual-time functionality — ideal for travellers and sport-watch enthusiasts.

Its sunray brown dial radiates depth and warmth, with applied luminescent indexes and a dedicated GMT hand that intuitively tracks a second time zone. The date window at 3 o’clock enhances everyday usability, while a scratch-resistant sapphire crystal with anti-reflective coating ensures long-term clarity and protection.
