Is the Marc Jacobs MJ3509 a good everyday watch?

Yes, if you want a simple designer watch. It is a basic quartz piece with a clean dial, so it suits daily wear, but it is not built for rough use or water sports.

Can I swim or shower with it?

Treat it as splash-resistant at most. Fashion watches like this are not meant for swimming or prolonged water contact, so take it off first.

Does it need winding or a battery?

It runs on a quartz movement, so it uses a battery. Expect a battery replacement every couple of years rather than daily winding.

How does it compare with other Marc Jacobs watches?

It sits in the same fashion-watch range as the rest of the line. Pick between them on case shape, dial and bracelet style, since the movement and build are comparable.

It works well as a gift for someone who likes Marc Jacobs and wants a dressier watch. The brand name carries the appeal more than the specifications do.
