Is the HydroConquest a true dive watch?

Yes. It is rated to 300 m, has a screw-down crown and a unidirectional rotating bezel, which are the core dive-watch features.

Does it have an automatic or quartz movement?

This reference uses a self-winding automatic movement, so it winds from wrist motion and does not need a battery.

How does it compare with the Tissot Seastar?

Both are Swiss automatic divers with 300 m ratings. The Longines adds brand heritage and finishing, while the Tissot typically offers similar specs at a lower tier.

What is the case size?

The case is 41 mm across with 21 mm lugs, a mid-size diver that suits most wrists but wears large on slim ones.

Is the crystal sapphire?

Yes, the dial is covered by a sapphire crystal, which is highly scratch resistant.

The watch on its two-tone stainless steel bracelet with a double safety folding clasp and diving extension, plus Longines paperwork.

Our take on the Longines Men's HydroConquest Black Dial Automatic L3.742.3.56.7

The Longines HydroConquest L3.742.3.56.7 is a 41 mm dive watch with a stainless steel case, a two-tone silver and gold bracelet, and a black dial. It runs on a self-winding automatic movement and is rated to 300 m, with a unidirectional rotating bezel, screw-down crown, date window and luminous hands and markers under a sapphire crystal. It suits buyers who want a Swiss automatic diver that works with a suit or a wetsuit. Against rivals like the Tissot Seastar and Oris Aquis, it leans on Longines' finishing and heritage rather than on a ceramic bezel or an in-house movement.
