Is the MK3979 a good everyday watch?

It works for daily office wear, but it is a dress piece. The steel bracelet and polished case show scratches with hard use, so many owners keep it for work and evenings.

Does it need a battery?

Yes. It runs on a quartz movement powered by a battery, which a jeweler replaces every couple of years. There is no automatic winding.

How does it compare with other Michael Kors watches?

It follows the same formula as the rest of the line: steel case, quartz movement, designer styling. Pick between models on case shape and bracelet style rather than on features.

Can I swim or shower with it?

Treat it as splash-resistant at most. Take it off for swimming, showers and washing dishes to protect the case and movement.

It is a common gift choice because of the brand name and bracelet look. Check the wrist size first, since steel bracelets often need links removed to fit.
