Is the Invicta Angel Pixie good for everyday wear?

It works as a dress watch, but the small dial and gold-tone finish suit occasional wear better than daily rough use. The 30 m rating means you should take it off for swimming or showering.

The case is 19.5mm across, which is small even for a women's watch. That keeps it delicate on the wrist but makes the dial harder to read.

No. It is rated for 30 m, which covers splashes and brief hand washing, not swimming or diving.

What movement does it use?

It uses a quartz movement, so it runs on a battery and does not need winding. Quartz also tends to keep good time with little upkeep.

What is the crystal made of?

It uses Invicta's mineral crystal. Mineral glass resists knocks reasonably well but scratches more easily than sapphire.

The gold-tone bracelet look makes it a reasonable gift for someone who likes small, dressy watches. Check that the recipient prefers a 19.5mm case before buying.
