Excellent timepiece.  Solid, heavy, stylish.  Well made.  Easy to set, and use.  Comes large.  Must be sized.  Wear with caution when working.  It's bulky, but fits well once sized.

Invicta uses the sapphire competing "Flare Fusion Crystal" on this piece I believe, which makes it extremely strong and scratch resistant, but I wouldn't test it.

Instead, wear it like it's made of glass, and rub it with a soft cloth REGULARLY to clean it.

You'll be glad you did.

It's a great piece, and has received numerous compliments while on my wrist!
