How big is the Invicta 12821 on the wrist?

The case is 40mm across, which is modest for a Pro Diver and fits most wrists without overhang. It suits buyers who find 43mm and larger divers too bulky.

Does the 12821 need a battery?

Yes. It uses a quartz movement, so it runs on a battery that needs replacing every few years. There is no automatic winding.

Can I swim with the Invicta 12821?

It is water resistant, which covers hand washing and rain. Treat it as a casual watch rather than a dive watch and avoid deep water.

Is the crystal scratch resistant?

Yes, Invicta lists the crystal as scratch resistant. It handles daily knocks, though heavy abrasion can still mark it.

What comes in the box?

Expect the watch, its bracelet or strap, and Invicta's paperwork. Check the listing for the exact packaging before ordering.

Is the Invicta 12821 good value?

Yes. It packs a chronograph, a scratch-resistant crystal and water resistance into a 40mm case, which is more than most quartz watches at its level offer. Compare it with plain three-hand Pro Divers if you do not need the subdials.
