Is this watch good for swimming and diving?

Yes. It is rated to 300 m with a screw-down crown and solid case back, which covers swimming, snorkeling and recreational diving. Have the crown screwed down and the seals checked periodically.

Quartz. It uses the Longines L157 movement with a battery end-of-life indicator. That means better timekeeping and no winding, but a battery change every few years instead of automatic winding.

How does it compare with the automatic HydroConquest?

The automatic versions bring mechanical winding, a sweeping seconds hand and no battery, usually at a higher price and with servicing costs. This quartz version is thinner, more accurate day to day and cheaper to own.

What size is it and how does it wear?

The case is 41 mm across and 10.2 mm thick, with a 20 mm band width. That is a mid-size diver that fits most wrists, and the slim case slips under a shirt cuff.

The watch on its two-tone bracelet, with Longines paperwork and warranty. Box contents can vary by seller, so confirm with the store before ordering.

Does the gold PVD scratch off?

PVD is a coating, not solid gold, so deep scratches can expose the steel underneath. Normal wear holds up well, but avoid knocking it against hard surfaces.
