Is the DKNY Broadway Maxi watch good for everyday wear?

Yes, if you accept mineral glass and plated two-tone steel. It is rated 5 ATM, so splashes and handwashing are fine, but take it off for swimming and showers to protect the plating.

Can I swim with a 5 ATM watch?

5 ATM means it resists splashes, rain and brief immersion. It is not rated for swimming or diving, and the water resistance depends on the caseback seal staying intact.

What size wrist does the 38mm case suit?

A 38mm case sits mid-size on most women's wrists and reads slightly large. The bracelet usually ships with extra links, so a jeweler can size it down for smaller wrists.

Does it have a date and is it easy to set?

Yes, there is a date window. Set the date with the crown in its first position and avoid changing it between about 9 pm and 3 am, when the date mechanism is engaged.

How does it compare with a Seiko or Citizen at the same level?

Those brands typically offer better movements and sometimes sapphire glass, but plainer designs. The DKNY wins on the two-tone look and the blue dial; the others win on long-term durability.
