Our take on the Longines Hydroconquest Automatic Grey Dial Men's Watch L3.782.4.76.9

The Longines HydroConquest L3.782.4.76.9 is a 43mm Swiss dive watch with a grey dial, ceramic bezel and rubber strap. Its L619/888 automatic movement runs at 25,200 vph and holds a 72-hour power reserve, which beats the 38-40 hour reserves of many entry Swiss divers. It is rated to 300m with a screw-down crown and sapphire crystal, matching the Seiko Prospex and Tissot Seastar on water resistance while offering a ceramic bezel and Longines' finishing. It suits buyers who want a serious dive watch that still looks at home with a shirt, though at 43mm and 11.9mm thick it wears large on slim wrists.

About the Longines Hydroconquest Automatic Grey Dial Men's Watch L3.782.4.76.9

The Longines HydroConquest L3.782.4.76.9 is a men's automatic dive watch with a grey dial. It has a round, brushed and polished stainless steel case, a ceramic uni-directional rotating bezel and a black rubber strap.

The dial has luminous silver-tone hands, Arabic numerals and circle hour markers, with minute markers around the outer rim. The date is at 3 o'clock. A scratch-resistant sapphire crystal covers the dial, and the case back is engraved.

A Swiss automatic movement, the L619/888 engine, powers the watch with a 72-hour power reserve. The crown screws down, and the watch is water resistant to 300 meters (990 feet). The strap closes with a brushed stainless steel deployment clasp with a foldover design.
