Is the Invicta Specialty 47419 a good everyday watch?

It works for office and evening wear and handles handwashing at 50m. The mineral glass and plated finish will show wear faster than a sapphire watch, so treat it as a dress watch rather than a beater.

50m water resistance covers splashes, rain and handwashing, but it is not rated for swimming or showering. Keep it away from hot water and diving.

What size wrists does the 36mm case suit?

36mm is a moderate women's size that suits most wrists, and the 18mm bracelet can be shortened by removing links. It wears slightly larger because of the all-metal bracelet.

Does it need a battery?

Yes. It runs on a quartz movement with a battery that typically lasts a couple of years and is replaced by a jeweller.

How does it compare with an automatic or sapphire watch?

It gives you the gold-tone steel look at a low cost, but you give up sapphire scratch resistance, luminous hands and mechanical movement. Rivals at higher levels offer those, at a higher outlay.
