Few days ago I was surprised by my grandfather when he showed me this Omega Gneve model. I've been looking for the case and dial model but I haven't found anything except from the caliber. The Cal. 267 looks good because my grandpa wasn't keen on automatic watches and changed it for quartz few months after purchasing it (new). I should take it to a watchman to a revision?? I think that the strap is not original. even not know if it could be gold. The main reason is to find information about case and dial! Thanks!
