A person wants to sell me this omega seamaster cal. 420, but I do not see any "swiss made", and the crown does not seem original to me ... what is your opinyon and how much should it be worth? I guess no more than € 50.

 

I'd save up for something better, looks like a money pit to me. At €50 you'd probably ending up putting a couple of hundred more into it to get it up to 'presentable' ... but one's things for certain, it will never be a show stopper!

 

Too much work to do with uncertain results, I'd pass on this.

 

Does it keep time?

 

Hard to say without seing the movement.
