Is the Tissot Carson automatic worth it?

It is a solid entry into Swiss automatics, with a chronograph and a scratch-resistant crystal in a dressy 30mm case. Buy it for the movement and looks, not for sports use.

How small is the 30mm case?

30mm is compact by modern standards and reads as a classic ladies' dress watch. It suits wrists under about 6.5 inches best; larger wrists may find it dainty.

Does an automatic watch need winding?

Yes. The rotor winds it while you wear it, but if it sits unworn for a couple of days it will stop. Wind it by hand or use a watch winder to keep it running.

Can I wear it swimming?

It is water resistant, but the rating is not stated. Treat it as safe for handwashing and rain, not for swimming or diving unless the caseback gives a specific depth rating.

What comes in the box?

Expect the watch, a Tissot presentation box and paperwork. A metal bracelet or leather strap depends on the version you buy, so check the listing for the strap type.
