Is my arduino ok? SUPER NOOB ON THIS NEED HELP

I bought an Arduino UNO from Amazon Marketplace. It came with some stickers and a paper on a nice sealed (with a Made in Italy Quality Tested sticker) box. The thing is that right below and a little to right of the USB HUB, on WEBPAGE there is a cylinder thing that I think it is the Crystal Oscillator but I really don't know. My Arduino in the other hand doesn't have that instead it has a tiny one, Is it ok? Thanx in advance and happy holidays :)

Yes, the latest batch of boards have seemed they have substituted 16mhz resonators for the 16mhz crystals.
