With the Longines HydroConquest you truly are prepared to venture into the deep. This watch delivers many useful and practical features, including a 300 m / 30 atm water resistance, a protected screw down winding crown, a closed case back, and a uni-directionally rotating stainless steel with black-colored ceramic insert bezel.

The stainless steel case measures 41 mm in diameter, 15.8 mm in height, and rests upon a stainless steel bracelet with a double locking fold-over clasp.

Beneath the scratch-resistant sapphire crystal you will encounter a black dial that sports a large Arabic 12, a date window between 4 and 5, and a small seconds counter at 9. Chronograph functions include a center seconds hand, a 30-minute counter at 3, and a 12-hour counter at 6. Luminescent hands and markers make telling the time quick and easy in low-light situations.

This is a self-winding automatic watch driven by the Longines Caliber L688 with column-wheel architecture. From its magnificent dive capabilities to its stellar construction, we are confident that the Longines HydroConquest will make an excellent addition to your collection.
