Could I please get some advice on this http://www.ebay.com/itm/VINTAGE-OMEGA-BUMPER-CALIBER-354-/221151202518?ru=http://www.ebay.com/itm/VINTAGE-OME...=&orig_cvip=true&rt=nc&_trksid=p2047675.l2557Purchases made through these links may earn this site a commission from the eBay Partner Network Is there a problem with the movement and the case-back, hence the circular marks? Also the seller says the dial is original but would rather hear that from here! Thanks for your time.
