Pocket Watch Meaning

Is ce''Fullmetal Alchemist poche''travaillent actually watch?

Hello, I was browsing for a pocket watch Fullmetal Alchemist to buy and found one that I would buy here: http://www.milanoo.com/Fullmetal-Alchemist-Cosplay-Pocket-Watch-p23567.html now to the question I do not really know if it works or not.By I mean … Is this just an accessory or does it really show the time?. Everyone can meet and even those who bought watch from different site.Thank you.

I have a pocket watch, it was not purchased from there, but I know gives the correct time (and mine) without fault!
