A true benchmark among sports watches. The Longines HydroConquest GMT 43mm enriches the HydroConquest collection with a second time zone function. Inspired by the world of boating, it combines robustness, legibility, and precision.
Water-resistant to 300m, this automatic GMT watch is designed to accompany both trips and aquatic activities. It features an exclusive caliber equipped with a silicon balance spring and offers high resistance to magnetic fields.

The round 43mm case is made from stainless steel and paired with a uni-directional ceramic bezel. The scratch-resistant sapphire crystal with anti-reflective treatment on both sides ensures optimal legibility.
The screwed case back and screwed crown guarantee water resistance up to 30 bar. Applied indices and rhodium-plated or gold-plated hands depending on the version are coated with Swiss Super-LumiNova® for clear reading in low-light conditions.
The stainless steel bracelet provides strength and comfort for everyday wear.
