Doubts about the crown and the price of this moderately worn Geneve cal. 603

Hello everyone,

I am thinking of grabbing another vintage Omega Geneve, only this time a gold plated cal. 603 (since I can get it very cheaply). But I have a few doubts.

Firstly, is the crown on this one fake since it does not have an omega logo on it.

I saw this post online with the same model (although it says cal. 601 which I believe to be a mistake) and this watch does not have the logo on the crown either. https://watches83.com/en/603-omega-...watch-hand-winding-cal-601.html#other-views-9

Secondly, what might the price of the watch be, especially taking into considerstion the engraving on it? It runs well, but needs a full service of course.

Thank you very much

It's not "fake" so much as a generic replacement. I would pay no more than about $300 for this and in fact sold one a hell of a lot nicer with a 565 movement for about that amount.
