I don`t want to buy it is from my grandfather. I just want to know the model to know about it because also my father loved it and for my is important because it remember to them.
It looks like an Omega Goliath/Crystal Ball from 1904 which I believe was designed to hang from a stand. This page has a picture on the right. http://www.omegamuseum.com/first-100-years As to originality and/or value, I have no idea.

Picture posted here: (thanks) The caption reads: The OMEGA Crystal Ball 1904, an eight-day going desk timepiece. This "Goliath" watch was produced in three generations, first in 1904 then again in 1910 and finally in 1917.

Because you were finished posting photos that provided little to no useful information. Read the link the @CanberraOmega posted.
There are many popular fakes of the crystal watch around but I feel that this is genuine, however I would beed to see the back of the watch to be sure.
