Is the HydroConquest 41mm 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.

How long does it run without winding?

The Longines Caliber 619/888 has about 72 hours of power reserve, so it keeps running through a weekend off the wrist.

Does it work as an everyday watch?

Yes. The 41 mm case and steel bracelet suit daily wear, though the 11.9 mm thickness makes it sit tall under a tight shirt cuff.

The watch and the manufacturer's packaging.

How does it compare with the Tudor Black Bay 41?

Both are Swiss automatic dive watches with 300 m-class water resistance. The HydroConquest has a slimmer, more classic case profile, while the Black Bay is thicker and more vintage-styled.

Is the crystal scratch resistant?

Yes. It uses sapphire crystal, which resists everyday scratches.
