Is the Marc Jacobs MBM3443 a good everyday watch?

Yes, for style-led daily wear. It is a simple quartz watch with a clean dial, so it reads easily and needs little upkeep beyond a battery change every few years.

Does it have a date window or chronograph?

No. The MBM3443 is a time-only design, so it has no date, stopwatch or other complications.

Can I swim or shower with it?

Treat it as splash-resistant at most. Marc Jacobs fashion watches are not built for swimming or diving, so take it off before water activities.

How does it compare with Michael Kors or Kate Spade watches?

They sit in the same fashion-watch tier with quartz movements and designer branding. Choose on case shape and dial style; none of them offers the specs of a dedicated watchmaker.

It works well as a gift because of the brand name and classic round case. Check the recipient's wrist size and whether they prefer a metal bracelet or a leather strap.
