Keeps great time
This is actually prettier than I thought it would be and I am tough on everything I wear. Never know what the day will entail, so when I clean it at the end of the day, it’s pretty shine comes right back.
I’m pleased with it.

Very hard to see the HANDS, but pretty
Very pretty and I didn't have to remove links. Hard to see the hands unless you angle it in the light. I'm not sure if I'll keep it. I'll give it some time ..lol and see how it goes before Amazon's 30 day policy.

just makes it around my large wrist - but very pretty
If you also have a large wrist like I do, well ... try it out. Bought it to look delicate and pretty at my son's wedding, to match color of gown. Which it does.
Side note: the hands are cobalt blue, for some reason! But you'd have to look up close to discover that. It doesn't take away from the overall look I wanted.
Edit: !@#$@! - it BROKE halfway through the wedding! During the dancing, I discovered it on the floor.
Downgrading this to one star, of course.
