Is the Longines HydroConquest a true dive watch?

Yes. It is rated to 300 m (30 bar) with a screw-in crown, screw-down case back and a unidirectional rotating bezel, which covers recreational and light professional diving.

How does the silicon balance-spring help?

Longines says the silicon balance-spring makes the movement up to ten times more resistant to magnetic fields than ISO 764 requires, which matters around phones, laptops and speakers.

How long does it run without winding?

The automatic movement has a power reserve of up to 72 hours, so it keeps running through a weekend off the wrist.

Will the 41 mm case fit a smaller wrist?

The case is 41 mm wide but 49.4 mm lug to lug, so it wears large. Try it on if your wrist is under about 6.5 inches.

What comes in the box?

The watch on its stainless steel bracelet with a double-folding safety clasp and micro-adjustment, along with Longines paperwork and warranty.

How does it compare with the Tudor Black Bay?

Both are Swiss automatic divers with ceramic bezels and around 70 hours of reserve. The HydroConquest is thinner on paper than some Black Bay models and uses a silicon balance-spring, while the Black Bay carries more brand cachet.
